Please do videos in mri .This way of teaching is good.please try to do it for mri as well

Thanks for your vote of confidence. I’m trying to round out the videos on X-ray first then I’ll see what I can do about MRI. I’m not as knowledgeable on mri but I can see.

Thanks for the nice video. Doesn't the tube current need some time to settle once modulated to a new value? Wouldn't this cause image artifacts?
@HowRadiologyWorks 9 ай бұрын
The tube current modulations are typically smooth and continuous functions so they do not cause artifacts

Thank you, great video. Is there any way to calculate the power of the x-ray (in Watts) when the mA is modulated? I know the formula only for the constant mA (w*kVp*mA).Thanks

At any time point that formula is correct and if you want an average over time you can replace the mA in your formula with the average mA of the acquisition

@@HowRadiologyWorks don't you know if I can find this average current somewhere in acquisition parameters on Siemens?

So if humans were perfect cylinders with equal distribution of bone and other anatomy, mA modulation would not be needed 😮

Yeah as long as we were centered and circularly symmetric we wouldn’t need angular modulation. Thanks Amy for leaving your first comment.
