Love the analogy with Google translate!

Great Lecture

Great lecture. Thank you very much.

more enlightening i enjoyed the lecture

Outstanding.

Interesting. Thank you for the tutorial. However, @ 16:07 I do not see any difference in noise but the Filtered Back Projection does seem to be a slightly sharper image than the Iterative Reconstruction. Given that the FBP requires less computer power, why is the IR method preferred?

You're welcome! The subtle difference in image noise may be partly obscured because of the compression involved in serving video over KZread. I'll post a PNG image of this slide in the "Community" tab which may be able to show the subtle difference a little better. Creating a CT image with fewer x-ray photons (i.e. lower radiation dose) is generally associated with slightly lower signal-to-noise on your CT image (i.e. more image noise). Since iterative reconstruction images tend to be less noisy than filtered back projection images, using IR may permit us to get images of similar diagnostic quality as FBP while using slightly less radiation on our patients than if we had used FBP.

Perfect 🎉

how does the CT slice affect the resolution of the image, 16 slice vs 128 or 256 slice

Thank you

Thank you 😊

Sir I am huge fan of your lectures. Will it be possible for you to make a lecture dedicated to chest CT technical aspects? I am a pulmonologist

Thanks! What particular technical topics did you have in mind?

particularly for contrast and CT pulmonary angiography.. time sequence for injecting the dye so as to visualise the vessel@@radiologyframeworks

Thank you so much for this!

Can I have the presentation?

You can find a link to a PDF of all of these slides, just by going to the video and expanding the “Description” section underneath. You’ll find links of this type for almost every one of my talks in the Description area of each video.
