In intensity modulated radiotherapy (IMRT), the optimal plan for each patient is specific due to unique patient anatomy. To achieve such a plan, patient-specific dosimetric goals reflecting each patient's unique anatomy should be defined and adopted

Purpose: To calibrate an algorithm for digitally reconstructed radiographs(DRRs) such that synthetic projections cast through an object in a fan‐beam CT (FBCT) optimally match cone‐beam CT projections of the same object. Methods: Our DRR algorith

Background In regularized iterative reconstruction algorithms, the selection of regularization parameter depends on the noise level of cone beam projection data. Objective Our aim is to propose an algorithm to estimate the noise level of cone beam pr
