Filtered backprojection algorithm for Compton telescopes
Abstract
A method for the conversion of Compton camera data into a 2D image of the incidentradiation flux on the celestial sphere includes detecting coincident gamma radiation flux arriving from various directions of a 2sphere. These events are mapped by backprojection onto the 2sphere to produce a convolution integral that is subsequently stereographically projected onto a 2plane to produce a second convolution integral which is deconvolved by the Fourier method to produce an image that is then projected onto the 2sphere.
