Method for reconstructing computer tomographic image data of patient, involves straightening projections under utilization of variable and/or weighting complementary projections under utilization of variable

摘要

The method involves detecting measuring data (P) during relative rotation movement between two radiation sources (C2, C4) of a computer tomography system (C1) and a monitoring object as projections by detectors (C3, C5). The detectors are attached to the radiation sources, and a variable is determined per projection, where the variable represents existence of scattered radiation from the radiation sources. The projections are straightened under utilization of the variable and/or complementary projections are weighted under utilization of the variable. Independent claims are also included for the following: (1) a control- and processing unit for reconstructing image data of a monitoring object (2) a computer program comprising instructions to perform a method for reconstructing image data of a monitoring object (3) a computer program product comprising instructions to perform a method for reconstructing image data of a monitoring object.
