Technical Note: Iterative megavoltage CT (MVCT) reconstruction using block‐matching 3D‐transform (BM3D) regularization

PURPOSE: Megavoltage CT (MVCT) images are noisier than kilovoltage CT (KVCT) due to low detector efficiency to high‐energy x rays. Conventional denoising methods compromise edge resolution and low‐contrast object visibility. In this work, we incorporated block‐matching 3D‐transform shrinkage (BM3D)...
