Very useful, and interesting explanation. I have an appointment for one of these scans tomorrow and was curious to understand how photon-counting technology works. I'm a little apprehensive now!
Glad to hear that!! May I ask where are you where do you live? I was researching this topic and I learned there were only 3 of these in the world as of January 2022
@@eduardorojas881 I had my scan on 20 May 2024 at the John Radcliffe Hospital in Oxford, England. I was told that this scanner was the only one in the UK and that there are only four in the whole of Europe. I guess there are more in the US and, maybe, elsewhere. It was an incredible machine and I was lucky enough to be shown some of the images - like 3D, HD colour images of the inside of my chest! Quite amazing!
The technology used is slow. Takes too long to convert the Xray energy into light then finally the electrical signal….conventional detector New technology is able to skip the conversion of photons to light then to electrical signal.. and is able to directly get an electrical signal from detecting the photon. This is much faster and able to reconstruct more useful and more detailed image. If you think of conventional detector like me taking 5 months to reply to you,,,, and let’s say I still have hundreds of comments to reply to… vs new technology I reply right away 😀🤣 and able to keep up with the speed of it all.
