Indirect Thin Film Transistor Array (Flat Panel) | X-ray Physics | Radiology Physics Course #35

Hi! Quick question - you refer to the sensitive region in the DEL as the 'photosensitive' region, but from my understanding it is essentially detecting electrons? Is there a reason it is photosensitive specifically (and doesn't this create implications for noise from any penetrating unconverted photons?). Let me know if I am misunderstanding here - thank you for the great explanation, it is very clear and useful!

Always wait for your videos, they are superb. Very nicely explained n presented

[@radiologytutorials]

Thanks a lot Fazal 🙂

[@lohith4493]

All your videos are so good and very well explained, thank you very much 🙏

[@radiologytutorials]

Thank you Lohith. I’m so glad they’re helpful 🙂

SO HELPFUL!

[@DocRad3]

Sir , In TFT - More pixel more signal better resolution?? It should be less resolution ??

[@lydiabasimbe2617]

I appreciate your dedication.you teach me so well. God bless you

[@radiologytutorials]

You are so welcome. Thank you for watching 🙂

[@IkramToubal-x7d]

Thank you so much, this is helped me so much I have exam in 2 days and I started now studying , this is saved My time thanks again

[@radiologytutorials]

I hope your exam went well!

I have seen this video recently.it is good but i have gotten some confusion.is the sensitive area of DEL is( a -Si) or onlt part of thin film transistor.some sources say it a -Si?

[@josebonilla4544]

very nice done. You can repair this array tft?

[@EoinFurbank]

Just so there is no confusion. The symbol used for a capacitor should be -| |- the one used in the video is for "ground". unless I am missing something of course!

[@radiologytutorials]

Yes! You’re right. I wasn’t trying to make a specific symbol 😅 just a diagrammatic representation! Ground would have one less line. In hindsight should have used the actual electrical symbol 🤷🏻‍♂️ well picked up
