CT Image Noise (Dependence on Technical parameters)

CT Image Noise depends on the technical parameters used in the imaging and in this video we cover the dependence of the image noise on the technical parameters including:
The dependence of CT image noise on mA.
The dependence of CT image noise on kVp.
The dependence of CT image noise on the slice thickness.
The dependence of CT image noise on the plane spatial resolution.
The dependence of CT image noise on the helical pitch.
The dependence of CT image noise on the rotation time.

This is true in general. But do you know what is the impact of deep learning on noise and those technical parameters? A DL algorithm can give equivalent images at low dose and high dose and those mAs relationship may fail?

Thanks John, yes you are right as I mentioned these relationships are for guidance and were derived for standard kernels and FBP. I agree that denoising operations do modify this behavior.

It's a bit funny that you talk about image noise and upload a jerky low-res video with bad sound :)
