Abstract
The present invention provides a method and an apparatus for reconstructing images from data acquired during radiotherapy. The approach is based on summing the imaging data acquired while both therapeutic and imaging source are active, with that acquired when only the therapeutic source is active. Further correction of the summed data can lead to reconstructed images of excellent quality.
