Improve cooling in ct scanner
Witryna23 mar 2024 · Computed tomography (CT), also known as, especially in the older literature and textbooks, computerized axial tomography (CAT), is an imaging modality that uses x -rays to build cross-sectional images ("slices") of the body. Cross-sections are reconstructed from measurements of attenuation coefficients of x-ray beams passing … Witryna3 kwi 2024 · The mAs or the dose of a CT scan has a direct relationship with the number of photons utilized in the examination. A useful relationship to keep in mind is: 2 x mAs = 40% increase SNR. Increasing the dose of the scan will decrease the amount of noise and hence improve the contrast resolution of the image. However it comes at a cost, …
