Abstract
A radiation delivery system includes a multi-leaf collimator (MLC) that includes a housing, a plurality of leaves disposed within the housing, and an image sensor disposed within the housing at a position that is offset from a beam axis. The plurality of leaves are movable to define an aperture for the MLC, and the image sensor is directed toward the plurality of leaves. The image sensor is to generate an oblique-view image of the aperture. The radiation delivery system additionally includes a processing device to receive the oblique-view image, transform the oblique-view image into a top-view image having a reference coordinate space, and determine whether the aperture for the MLC corresponds to a specified aperture based on the top-view image.
