Measurements of multidetector CT surface dose distributions using a film dosimeter and chest phantom

Purpose: This paper uses film dosimetry to investigate the relationship between multiple scan parameters of multidetector CT with automatic exposure control (AEC) and the surface dose distribution produced on a chest phantom.Methods: The characteristics of the film used in the film dosimeter were ev...
