DYNAMIC SELECTION OF PROJECTION ANGLES FOR TOMOGRAPHIC RECONSTRUCTION

摘要

A method (10) for determining a projection angle for use in tomographic imaging, the method (10) comprising obtaining (11) projection data comprising at least one projection view from at least one projection angle, the at least one projection view being generated by scanning of a test object (3) with a tomographic imaging device (5), each projection view comprising at least one observation value obtained at at least one detection location, providing (12) a plurality of candidate projection angles, for each (20) candidate projection angle, calculating (13) a function value indicative of an amount of information that may be gained by adding to said projection data a further projection view generated by scanning of the test object (3) with the tomographic imaging device (5) from said candidate projection angle, and selecting (14) a candidate projection angle from the plurality of candidate projection angles taking into account said function values. A corresponding system and computer program product also is provided.
