Fig. 3From: Implementation and experimental evaluation of Mega-voltage fan-beam CT using a linear acceleratorThe example profiles of mean attenuation (a) and detector anomalies (b) from the sinogram shown in the inset. The mean attenuation was calculated by averaging the measured attenuation along the view direction. The magnitude of detector anomalies was the difference between the mean attenuation and the smoothed mean attenuationBack to article page
