摘要：
A method of reconstructing a volume image of an object includes receiving circle projection data collected by a detector along a circular path with respect to the object receiving line projection data collected by the detector along a linear path with respect to the object producing a reconstructed circle path volume image of the object from the pre-processed circle projection data using a reconstruction algorithm that includes a ramp filter producing a reconstructed line path volume image of the object from pre-processed line projection data using a reconstruction algorithm that includes a Hubert filter and combining the reconstructed circle path volume image and the reconstructed line path volume image to produce the volume image of the object. An apparatus and computer program product are also described.
