Image NPS for the mobile CT (Airo) in comparison to diagnostic CT (Philips Big Bore). (a) Transverse plane NPS in helical mode, each with “standard” reconstruction filter and comparable dose (10.1 and 9.9 mGy, respectively), illustrating a factor of ~2 in spatial‐frequency cutoff between the two systems. (b) Transverse (f_x,f_y) and (c) coronal (f_x,f_z) plane NPS for the Airo (top) and Big Bore CT (bottom), each with “standard” reconstruction filter and comparable dose. NPS, noise power spectrum.
