Patent ID: 8666137

Claim:
A projection values processing apparatus for processing acquired projection values, the projection values processing apparatus comprising: an acquired projection values providing unit for providing acquired projection values, a reconstruction unit for reconstructing a first image from the acquired projection values under consideration of a reconstruction assumption, a simulated projection values determining unit for determining simulated projection values by simulating a projection through the reconstructed first image under consideration of the reconstruction assumption, a difference determining unit for determining differences between the acquired projection values and simulated projection values by subtracting the respective acquired projection value and the simulated projection value corresponding to the respective acquired projection value from each other for generating subtraction result, reconstructing a subtraction image from the subtraction results determined for the acquired projection values, and simulating a projection through the reconstructed subtraction image, an inconsistency determining unit for determining inconsistency values for the acquired projection values, wherein an inconsistency value is indicative of a degree of inconsistency of a respective acquired projection value with the reconstruction assumption based on the determined differences.
