Phantom evaluation of small‐pixel effect in ultra‐high‐resolution photon‐counting CT: Noise texture and high‐contrast spatial resolution
Abstract Background Ultra‐high‐resolution (UHR) photon‐counting CT (PCCT) with small‐pixel detectors improves resolution and noise, but its dependence on diverse imaging conditions remains insufficiently characterized. Purpose To systematically evaluate the small‐pixel effect in UHR PCCT by assessing noise properties a...
