Can I please clarify - increasing pitch will increase noise? Therefore increasing pitch will decrease signal noise ratio, leading to poorer contrast resolution

Hi Diana, thanks for the question. Signal to noise ratio is essentially a function of how much information you are collecting. Anything that decreases your radiation dose from the source is going to decrease the total amount of radiation hitting the detector, and decrease our overall signal. Less signal means more noise. Regarding pitch - if the pitch is higher, that means the patient is moving through the scanner faster relative to the speed of gantry rotation. There is less exposure time per volume of body tissue, and for pitch >1, there "gaps" in between helical rotation in which information is not acquired from all sides at all levels in the Z-axis. All of this combines to mean less radiation dose to the patient, less radiation to the detector, less signal, and thus lower signal to noise ratio (= more noise!) Hope this makes sense :)

One of the best lecture I have ever seen on these topics they are very confusing but u make it simplee need more and more vidoes
