PHOTON Counting CT, How PCT works.

[@trippinluv]

Great recap! Interesting to see the 2 different approaches to PCCT detector design. Thanks!

Wow , advanced very informative comprehensive lecture. Thanks a lot 👏👏

[@HowRadiologyWorks]

Thanks Ardo Vitamins. Glad you enjoyed it. PCDs are definitely more complex. Glad you made it through the presentation 👍

This is amazingly informative and really broken down in an easy to interpret fashion. I was wondering if you had any cited sources for continued reading and research?

you help me in my career as service engineer for ct and xray machines

Thanks Yousef. Glad to help

Should the X-axis of the plot starts at 8:41 be incident counts and the Y-axis be the measured counts since I believe you are going to talk about the effect of the deadtime

It’s very interesting. I wonder what is usefulness of photon counting detector in single energy imaging apart from electronic noise?

[@HowRadiologyWorks]

John did you watch till the end? The main advantages additionally are spatial resolution and the ability to more optimally weigh the photons in making a combined single energy image

[@johnal3358]

@@HowRadiologyWorks great point about the equal weighting. However I’m not sure about the improvement in resolution as the CT detector pixel size is ~1mm and there is no more 150 um optical spread of light, hence not a large difference. I can definitely imagine the resolution improvement with photon counting detectors in small pixelated chips. Keep the great work. It helps retirees like us to get in touch with the technology.

I’ve got a couple votes for Kermit on another video. Not sure if Manny or Kermit is more flattering
