Photoacoustic imaging is an emerging imaging technique that shoots micro-pulses of laser light at a specimen or body part, which selectively heats up parts of the tissue causing them to expand, and generate waves of pressure -- a.k.a. sound waves.
Ultrasonic sensors are situated to capture these microscopic changes, and a processing software then reconstructs the image based on what the sensors “hear.” The speed of the laser can be adjusted depending on what type of tissue one would like to visualize.
The photoacoustic imaging technique is beginning to take off in both the medical and scientific worlds, as it provides us with super clear, incredibly detailed images of the human body and the structures inside it.
Not to mention, the imaging technique causes no discomfort and there is no dangerous ionizing radiation involved, making it a desirable alternative to more traditional imaging, like a CT scan, ultrasound, or a PET scan.
Not only can this new imaging technology be used to image tissues at extremely high resolution, you can also introduce a foreign material, like a contrast dye or a specially designed nanoparticle, to see things you might not be able to otherwise.
Although the technique has been around for more than a century, photoacoustic imaging is just starting to be clinically explored as an alternative and prototype clinical machinery is in development.

Photoacoustic Imaging
www.ncbi.nlm.nih.gov/pmc/arti...
"Possessing many attractive characteristics such as the use of non-ionizing electromagnetic waves, good resolution/contrast, portable instrumention, as well as the ability to quantitate the signal to a certain extent, photoacoustic techniques have been applied for the imaging of cancer, wound healing, disorders in the brain, gene expression, among others."
Photoacoustic imaging enables scientists to step up war on cancer
www.ft.com/content/c023c7a2-f...
"Photoacoustic imaging delivers exquisitely detailed images of biological tissue purely by listening to the sound that light makes. Ultrashort pulses of laser light of a few billionths of a second are directed at the tissue and selectively absorbed, depending on the colour of different constituents of the tissue."
The Eclectic History of Medical Imaging
www.itnonline.com/article/ecl...
"In the 1940s and early 1950s, shoe salesmen flipped a switch and shoppers could see their toes wiggling on fluoroscopes. At their height, some 10,000 of these devices were in use at shoe stores across the United States. X-rays, emitted by a tube mounted near the floor, penetrated the shoes and feet, then struck a fluorescent screen on the other side."

This sounds like a major medical breakthrough.
AvangionQ we have a lot of cool technology today, and this does seem like brand-new cutting edge tech, however I would caution you not take everything on this channel at face value. I have stopped watching Seeker a while ago because a lot of their videos have clickbait titles where they bullshit about the science and make it seem like a major breakthrough, when in reality it isn’t. I think they had a video talking about the effects of particles under observation, and they completely misinformed the viewer with their “explanation”, choosing to omit the fact the equipment used to observe the particles actually interferes with them, and making it seem as if they were somehow sentient. They do all they can to maximise the amount of views they get, which is a shame because a lot of the stuff they talk about is really interesting, however they inflate, exaggerate, and twist it to make it seem more than it actually is, if you get what I mean.
Yep
@@ousarlxsfjsbvbg8588 well, from the image produced by the technology, it looks much better than the currently existing technologies, and it may replace many invasive exams, in fact, this image looks more clear than the invasive ones.
By the sound of it, I think you're right.
If it's legit, then absolutely.
Nice! Finally a viable improvement to Human diagnostics. Our scanning tech is in dire need of a serious upgrade.

: "Bell! that damn copycat"
I'm concerned this won't become widespread in the US because of the rampant price-gouging
Isn't that almost always the issue? Greedy people slow down the progress of our society significantly!
@@jaycamacho2021 , yep. The great science bottleneck. Even cool breakthroughs get tabled and never picked back up due to low immediate profitability/high investment risk. Long-term progress takes a back seat to immediate monetary gains nowadays.
Just to play devil's advocate here, but it is this very thing that drives innovation and research and is why it will be widespread in the US compared to other places around the world. The truth is you won't see it widespread in places like Canida or the UK because of the minimal and limited care. On a similar note I understand why some Americans might like the idea of a socialized government-operated healthcare system but why on earth would a Canadian ever want America to go that route. What would Canadians do when they need rapid high-quality care, they can't get it in their own country. Obviously, if you have the sniffles in Canada their healthcare system is amazing but if you have anything even kinda serious then you can't deny that universal healthcare systems just can't handle it on any large population scale and is why so many people have to travel to America to get treatment. The US healthcare system is constantly being bombarded by people from other countries needing medical treatment they can not get in their own country and that includes Canida and the UK. Why do you think that is? It not because the American healthcare system is perfect, it's absolutely horrible in some areas and has major room for improvement. But at the end of the day, it allows for competition and monetary gain that drives cutting edge research and innovation. Whereas socialized medicine has shown to be a dagger in the heart of innovation. The healthcare field in many of these countries has gone stagnant, Canida had to learn the hard way with an influx of patient deaths before they gave their people a private option. I think they call them super hospitals, where as America just calls them hospitals.

This is groundbreaking and is a great development for women's health as well.

Thanks to you..
Thanks for the video seeker..🙏👍😊
WoW, that's amazing. We're getting closer to the *star trek tricorder*

I guess Doctors can check my heart now since I have a pacemaker installed which doesn't allow MRI.
Fintan Damn straight it takes a long time just as it should. You don’t want to use something on the average healthy person without knowing its long term effects.
Jamilul Huq you can get a 2D echo or chest CT scan
Echo, NM cardio stress tests will not harm a pacemaker.
@@Sr89hot They did echo a couple of times within a gap of two years but they think I should rather have to undergo angiogram.
I’ve had an mri and have a pm
How amazing are those images? Seriously. As a clinician, I can barely imagine how transformative this could be - definitive imaging in real time, by the patient's side, just like an ultrasound, but on steroids.
As a medic, I think it would be nice to have something like this on an ambulance. Imagine being able to determine a closed fracture in the field, instead of doing the whole spiel about how you should probably go to the hospital to get checked out because I don't have x ray vision. Now we could, and we could be saving people thousands of dollars in wasted hospital visits. This is just thinking about something simple like fractures. Imagine this as a diagnostic tool to rule out pulmonary embolism are being able to get exact information about a myocardial infarction. Something like this in the field could save lives. An interesting future.
Extraordinary research.
Extraordinary episode by Seeker.
Love
I congratulate the amazing and wonderful scientists that made this amazing technology possible.
*Finally!! The person behind all the voice over Videos of Seek on CZcams is in person*
She's been "in person" in numerous videos.
Are you telling me that every time a sci-fi tried to tell me the character was looking through walls with x-ray visors it was actually laser acoustic imaging?
*YES*
Around 1994, when I was an industrial engineer, we got some sample CCD array chips that worked on passive xrays from Motorola. You could see through walls and stuff with them, just like in the movies. We were writing software to scan produce for internal defects. About a month into the project, we were ordered to return all of them. All technical information on them just disappeared. It was like they never existed at all, but am sure that they are in some military stuff now.
Kind of explains how Superman can see through walls, he has laser eyes 😁
We've known that sound waves are multi-talented, so it's very exciting to hear that lasers that "hear" sound are finally being put to use in the medical field. I'm very excited to see how accurate this new technology is going to be.
Imagine what will happen in 50 years crazy how fast our humanity is growing
The future looks promising
This is legitimately one of the coolest things I've ever seen.
With a technological advancement like this, the Star Trek Medical Tricorder feels just around the corner.
I love how you love your subject matter. Keep up the good work, your excitement rubs off.
Great can't wait to get a loan pay off the medical bills.
In part what you are saying it to prevent the use of drugs that is good and useful, I’m white and surely you are white too, the only thing I have to say that whites can seduce and have strong sexuality too, and today there is some kind of problems between whites that if you have a strong sexuality is to have a pathology, perhaps that kind of white sexual represion women start looking blacks, surely if this song was of a black person you surely wouldn’t say anything about this song.

I spent 8 daily hours watching youtube daily, and is the first time this channel is recommended to me
Finally! This is revolutionary because using Quantum Entanglement, we could create teleportation. Using the lasers to detect specific atomic structures, we could calculate every particle in an object and recreate the exact structure in a different location. Teleportation wasn’t an issue, so much as how to teleport a massive item with tons of individual atoms/particles. They’ve already teleported particles across some remote islands somewhere; I’ve forgotten the exact details already.
This'll be a feature on a smartphone soon I bet!
nice idea...
Maybe

It is amazing that with filming you can study with medicine, it would be amazing that this together with the microscopy video you can explain how to digitize it to create simulations, audiovisual art with simulations digitized in 3D.
Could they combine this technology with key hole surgery to completely remove cancer more effectively than before?
@Yen Tao really hope someone tries this

This makes me happy that i am soon finished with my radiographer degree. Hoping to be working with this amazing technology in the future!
Just imagine, we have been pumping our bodies with x-rays, and then this comes out too late. Feels bad to be on the wrong side of history lol!
Yes but I can read at night now with the light off
That’s really awesome for sure! Will be great for detecting any anomalies in the body.
Could you use this technology for something like a detection device that could sense people from a distance? This is huge as far as medical technology goes, but what about military applications?

This is similar to Two Minute Papers’ video on seeing humans through walls using WiFi. Amazing that this is also a demonstration of vibration over and above wave function. What a time to be alive.
Any theoretical limit to the spatial resolution of this method? I'm thinking about the connectome, here.
This looks very promising for diagnosis and research
This should however only be able to make one type of structure visible at one time.
Which limits the applications, somewhat.
Still quite interesting.
Not really, they can do multiple scans (tuning the laser to highlight different organs/systems each time ) or use other methods to get a more thorough image.
you can go from specific to generic, but not the other way around.
@@remliqa
As I said, "at one time".
You can't just overlay different Scans, you'll lose a lot of details.
@@Pyriphlegeton
As I said, this is mainly a software (both is overlaying the scans and separating them o display different detail) challenge rather than a hardware based one.
@@Pyriphlegeton ever heard of superresolution microscopy? They had the same problem of how they were going to separate different fluorescent signals and solved it with a wandering laser illumination that scans the surface of your sample not all at once, but one piece at a time, allowing - together with photoquenching - for more detailed scans before the fluorophores got bleached.
The same could be applied here, having a rapid succession of scans with different wavelengths of laser light to image multiple organ systems practically at once. We're only limited by the speed of sound and computer power, so I guess you could image all relevant tissues in an area in almost-realtime, with no major downsides in quality exept that the picture only refreshes every 0.05-0.1 seconds...
Amazing! thank you. I hope to learn more
Grand idea, only 3 or 4 decades before something like this is approved for use.
Could this be developed in the future to identify cancer??
Coming soon to a CCTV near you.
Exactly
Fascinating ! I certainly could benefit from this technology.
It would be awesome to see this used for when people are getting acupuncture done, we would have a better understanding of how acupuncture works.
Actually Antonio Meucci invented the telephone. Fun fact that I learned from QI.
Not necessarily true and not necessarily untrue. Both versions had mechanical differences

I’m all for it. I had an M.R.I. done on me not to long ago. And one of my main concern was about the radiation affecting my body. But, this Ladies and Gentlemen is the beginning of a better future with out the crazy harmful radiation.
You have to hand it to the Japanese tho..
Terrific job in making new useful technologies.
Is this japanese tech?
I wish they could make an imaging test that objectively detects pain and show where in the body it's coming from and how bad it is, so they could prove that chronic pain disorders are real and people aren't just drug seekers.
Agree its a shame what has happened in that field. People who need pain medication cannot get it, because abuse is so out of control. I get it that people lie, but when you have medical reasons to be in pain, and still cant get pain medication is sux
You always have the coolest stories Maren.
Technology like this is a sign that mankind is advancing into the next phase. Every decade or so we get closer to being space-faring... I hope I live to see the first steps of inter-system travel.
I'm guessing this requires enormous amounts of computing power to pull off, which means it likely has only become feasible recently. This is really nifty. :-)
Perhaps combining A.I. neutral networks with cloud based peer to peer type systems could overcome the need for monster rigs?
@@johnswanger8474 - Well, even the idea to do that and the capability to do that are relatively new things.
@@Omnifarious0 Yeah, true. Well, consider the SETI@home project at UC Berkley. Something like that perhaps? I figured since medical imaging falls into HIPAA restrictions, perhaps using an A.I. network proprietary to the project could work as a gatekeeper to parse cpu cycles and bandwidth from the public cloud so that only processing power is harnessed with no client input/output possible.
I think quantum computing would be the answer but that's (as far as I know) not feasible any time soon.
@@johnswanger8474 - I get the impression that part of the appeal here is the near-real-time of the images. They contrast it with how long it takes to get an image out of an MRI scanner.

This sounds amazing! One thing I was wondering, however, is how do the lasers penetrate deeper under the the skin? I mean I get how you could image things near the surface, but what kind of laser can safely penetrate through our whole bodies (just curious, not critical)?
Do they have to? I thought it was the sound waves that were penetrating deep.
I probably just tore my ACL a couple days ago and now I’m waiting to get an MRI in a week and a half. This would be so cool to see if they could use this new technology to look at my ACL and find out if it is really torn so I can go ahead and get surgery.
That was really interesting.
My bathroom scale uses "body impedance" measure lot's of "quantities" in my body. Things like water quantity, fat weigh, muscle weight, bone weight, etc. I'd like to know what the science is behind this technology and how accurate it is.
"MRIs take _many minutes_ to produce an image"... Aren't we so technologically spoiled... Lol.
MRIs are a pain in the ass to the patient, even more when needs to be regular. Also, the metal implants thing is really a issue of the technology, and the machinery cost a LOT o money
Lucas Rodmo yeah but when you think about it, and compare it to the history of medicine-we do sound very spoiled
@@angelmonroy3012 It is not a bad thing that our generation has it better. What was and wasn't possible in the past doesn't concern me and probably doesn't concern a lot of other people. We aren't spoiled, we're just living in the future. Stop ruining it with your pointless arguments.

Wow, seems very promising! Reminded me of those Med-Bays' on that movie 'Elysium' (2013) where the system would scan and automatically identify the problems in the body! In the movie the device would go on and cure the decease, but I'm sure we'll get there someday. Hopefully it will be available for everyone and not only the ones 'up there'!
So 2019 is lights and 3D Printers
Didn’t Bob Lazar mention the government was using a similar technology to this years ago?

There are many inventions out there that are not feasable for mass production with current technology. Why there are no cheap electric cars? Because batteries are not that simple and they are still expensive to manufacture.
