Prior Frequency Guided Diffusion Model for Limited Angle (LA)-CBCT Reconstruction
Jiacheng Xie, Hua-Chieh Shao, Yunxiang Li +1
Cone-beam computed tomography (CBCT) is widely used in image-guided radiotherapy. Reconstructing CBCTs from limited-angle acquisitions (LA-CBCT) is highly desired for improved imag…
