IMAGING SYSTEM, IMAGING METHOD AND COMPUTER PROGRAM FOR IMAGING A REGION OF INTEREST |
摘要 |
The present invention relates to an imaging system for imaging a region of interest comprising an illumination unit and a detection unit. The imaging system further comprises a grouping unit for grouping the detection values, wherein each group comprises at least one alpha detection value and at least one beta detection value (103). At least one alpha aperture weighting value for the at least one alpha detection value of a group is determined by using at least one position of at least one ray within the aperture (104). Furthermore, at least one beta aperture weighting value for the at least one beta detection value of a group is approximately determined using the at least one alpha aperture weighting value of the group (105). The detection values are than aperture weighted using aperture weighting values (106). The region of interest is reconstructed by backprojecting the weighted detection values (107). |
