Abstract:
A method for reconstructing at least one image representative of an object with a scanning imaging system having a multislice detector array and a radiation source configured to emit a radiation beam through the object and towards the multislice detector array, the multislice detector array having a plurality of detector elements arranged in a plurality of detector rows, said method comprising:helically scanning the object with the scanning imaging system to acquire a plurality of projection views of the object, including projection views acquired at different cone angles of the radiation beam; selecting a region of reconstruction (ROR) to define sets of conjugate samples in the projection views; and reconstructing at least one image of the object, said reconstruction including weighting the sets of conjugate samples using a cone-angle dependent weighting function, and filtering and backprojecting the weighted samples.
