TWO-DIMENSIONAL TOMOGRAPHIC RECONSTRUCTION FROM PROJECTIONS WITH UNKNOWN ANGLES AND UNKNOWN SPATIAL SHIFTS
ICASSP 2026poster
In parallel beam computed tomography (CT), an object is reconstructed from a series of projections taken at different angles. However, in some industrial and biomedical imaging applications, the projection geometry is unknown, completely or partially. In this paper, we present a technique for two-di…
