Rotation Errors of Breast Cancer on 3D-CRT in TomoDirect

Progress in Medical Physics, 2015
‡The purpose of this study was to analyze the rotational errors of roll, pitch, and yaw in the whole breast cancer treated by the three-dimensional radiation therapy (3D-CRT) using TomoDirect (TD). Twenty-patient previously treated with TD 3D-CRT was selected.

Dose gradient based algorithm for beam weights selection in 3D-CRT plans [PDF]

Reports of Practical Oncology & Radiotherapy, 2014
In this work we test the usage of dose gradient based algorithm for the selection of beam weights in 3D-CRT plans for different cancer locations. Our algorithm is easy to implement for three fields technique with wedges defined by planner.3D-CRT is usually realized with forward planning which is quite time consuming.

Doses in organs at risk during head and neck radiotherapy using IMRT and 3D-CRT [PDF]

Radiology and Oncology, 2012
BACKGROUND.: Treatment planning for head and neck (H&N) cancer is complex due to the number of organs at risk (OAR) located near the planning treatment volume (PTV). Distant OAR must also be taken into consideration. Intensity-modulated radiotherapy (IMRT) and three-dimensional conformal radiotherapy (3D-CRT) are both common H&N treatment techniques ...
