CT Detectors (Computed Tomography Detectors)

- CT Detectors are the most important component in a CT system in determining the image quality in the system.
CT Detectors were previously made of ionization chambers which required high pressure gases.
Modern CT Detectors use scintillators and have a photodiode to read-out the electrical signal.
It is even possible to have a dual layer approach with scintillation based detectors to gain some spectral capabilities.

Thank you, interesting content. Video about photon-counting detectors will be great!
Thanks Anna
We added that video too now
Just came across your channel and this video has been of great help. Thank you for the value shared
Glad it was helpful! Thanks for leaving the comment.
Definitely a video on PCCT
Great overview! Love these videos.
Thanks
Thank you very much! Greetings from Switzerland!
You’re welcome, thanks for dropping your location. Fun to see these videos spreading around the globe.
thanks a lot for the explanation, i was struggling with finding understandable explanations for the different detectors used in CT's in spanish. Glad i found you !
Great. Are there okay Spanish subtitles?
there are none, but i can understand you just fine. Keep up the good work :)@@HowRadiologyWorks
Congratulations Brian, magnificent video, like all the ones you do.
I don't know if it would be possible to see real detectors and their minute components, we always see the schematic detector, but it would be very interesting to be able to visualize them in a real way.
Come on you can! New challenge!
Regarding the PCD, looking forward to seeing your video.
Kind regards!
Thanks for the comments. Yeah for a later video we can consider showing some parts. Is this something others would like to see too?
@@HowRadiologyWorks without a doubt, we always see schematics and rarely real photos.
@@HowRadiologyWorks yea i also would like to, i was thinking that the detector raw is (like an arch) composing of multiple slices then the raws arranged one by one next to each other😂
I was suffering understanding it, but with concentration of your real pics here you brought i discovered that they are like rectangles arranged side by side.
can you took about photon counting detector
Well explained.
Pass it on and thanks for the like and comment 😉
Thank you so much
You’re welcome
Excellent
Thank you! Cheers!
Thank you Brian for such a nice and simple illustrations of CT detector it really helps me in my studying.
Physics is pretty hard to be remembered
You're very welcome! Thanks for the comments.
brilliant 👏
Thanks for the high praise. I don’t get that everyday
How big were detectors in a single array ct scan machines ?? Anyone ?
10-20mm so a very thick slice was generated
good job...
Thank you! Cheers!
Can you explain in ct increase collimation or thinner slices?😊
Sure I have one video on multi row CT, what questions do you have specifically?
I am studying from Farr’s physics and I don’t remember I have read that word (photon count detector).
It might be a subject for a question in the FRCR EXAMS
I haven't read Farr's physics but photon counting detectors will take several years to hit the exams since they are just coming on the market now.
@@HowRadiologyWorks unlike what you think they aways pick up the new events and make it a question
Thanks a lot for updating our information 👏
I haven’t checked out Farr’s physics. I’ll take a look but photon counting is very new so maybe not in there yet and hopefully won’t be on the exams
@@abdovitamins6331 good to know thanks
Sir i got 22/25 marks in my MID Semister exams of my College.
Now i have my End Semister Exam let's how much will i got this time.
Thank You for Making these wonderful Videos ❤️❤️.
Good luck. I hope that these are helpful.
Can ct scan find out swallon fiber shard I have swallow optical fiber glass core core is as small as human hair can it be detect by ct scan
Hi Kapil I try not to discuss individual medical questions in the comments. A CT scanner can detect objects smaller than a human hair if they are very attenuating to X-rays. Most material that is similar to the background attenuation will not be detected if it is as small as a human hair.
@@HowRadiologyWorks first of all thanks for your reply sir but sir which fiber I have swallowed how to find out it it can be pain full I want to remove it what should I do can any ct scanner available to find out fiber in my body
Give me an answer sir
@@kapilkamble982 I’m sorry but as I mentioned we do not provide personal medical related advice on this channel. If you have an educational question on X-ray or CT technology please let me know
@@HowRadiologyWorks ok sir but i just want to know can CT scan find out micro glass fiber in the body please give me answer I'm in so much tention please tell me sir i request you
