Verification of In-Treatment Tumor Position Using Kilovoltage Cone-Beam Computed Tomography: A Preliminary Study

Three-dimensional tumor position during rotational dose delivery was evaluated by acquiring in-treatment kilovoltage (kV) cone-beam CT (CBCT) to ensure treatment quality. The CBCT projection data of a phantom were acquired during rotational megavoltage (MV) dose delivery up to 6 Gy to evaluate image...
