Process for improving the tomographic reconstruction of images or volumes from a limited number of measurement projections

摘要

Process for tomographic reconstruction of images or volumes from a limited number of measurement projections computed from wave beams. According to the invention, a reconstruction computed from interpolated projections is added to the tomographic reconstruction computed from the measurement projections alone, so as to improve the quality of the resulting tomography. This added reconstruction is obtained solely from the negative contribution of the interpolated projections. Application to medical imaging and to the non-destructive testing of materials. <IMAGE>
