EMPIRICAL BEAM HARDENING CORRECTION FOR DIFFERENTIAL PHASE CONTRAST CT |
摘要 |
A beam hardening correction method, a related calibration method for tomographic image data and a related apparatus. The tomographic image data includes attenuation data (f) and phase gradient data (g) and/or small angle scattering data (h). A correction value is computed from the attenuation data (f) by applying a function (q) to the attenuation data (f). The correction value is combined (S445) with the phase gradient data (g) or with the small angle scattering data (h). |
