Ultrafast Cone-Beam Computed Tomography: A Comparative Study of Imaging Protocols during Image-Guided Therapy Procedure

Table 3

Details of patient tumor characteristics determined using gold standard MR-image data. The determined tumor characteristics using MRI displayed separately for UF-CBCT imaging protocols 1 (P1) and 2 (P2) patient groups.
