摘要:
A method for scattered radiation correction acquires radiographic projection image data for a first portion of a subject that lies within a field of view of an imaging apparatus and characterizes the surface contour of the subject that includes at least a second portion of the subject that lies outside the field of view of the imaging apparatus. The surface contour of the subject is characterized according to the reflectance images. The surface contour characterization is registered to the field of view. Scattered radiation is estimated according to the projection image data and the surface contour characterization. The acquired radiographic projection image data is updated according to the estimated scattered radiation. An image of the field of view is displayed according to the conditioned acquired radiographic projection image data.
