The low-contrast and high-contrast resolution of the 320-detector-row CT does not differ from the conventional 64-detector-row CT scan from the same manufacturer. Phantom measurements demonstrated a low-contrast resolution of 2 mm at 0.3% Hounsfield unit (HU) difference and a high-contrast resolution of 0.35 mm. [Pg.29]

LP/mm as depicted in Fig. 3.4. The smallest high contrast object that can be resolved at 2.0 LP/mm has a size of about 250 pm or 0.25 mm. At native detector resolution (154 pm pixel pitch), the spatial resolution encountered in phantom measurements reaches almost... [Pg.42]
