Investigation of contrast-enhanced subtracted breast CT images with MAP-EM based on projection-based weighting imaging

Contrast-enhanced subtracted breast computer tomography (CESBCT) images acquired using energy-resolved photon counting detector can be helpful to enhance the visibility of breast tumors. In such technology, one challenge is the limited number of photons in each energy bin, thereby possibly leading to high noise in separate images from each energy bin, the… CONTINUE READING
