Dose calculation methods for photon beams are reviewed in the context of radiation therapy
treatment planning. Following introductory summaries on photon beam characteristics and …

Electronic portal imaging devices (EPIDs) have been the preferred tools for verification of
patient positioning for radiotherapy in recent decades. Since EPID images contain dose …

Purpose: To evaluate the heart and lung sparing effects of moderate deep inspiration breath
hold (mDIBH) achieved using an active breathing control (ABC) device, compared with free …

A study of the performance of five commercial radiotherapy treatment planning systems
(TPSs) for common treatment sites regarding their ability to model heterogeneities and …

AAPM Task Group 58 was created to provide materials to help the medical physicist and
colleagues succeed in the clinical implementation of electronic portal imaging devices …

BACKGROUND AND PURPOSE: In parallel with the increased use of intensity modulated
radiation treatment (IMRT) fields in radiation therapy, flat panel amorphous silicon (aSi) …

Tomotherapy is the delivery of intensity modulated radiation therapy using rotational delivery
of a fan beam in the manner of a CT scanner. In helical tomotherapy the couch and gantry …

Purpose: We present a new technique to improve dose uniformity and potentially reduce
acute toxicity with tangential whole-breast radiotherapy (RT) using intensity-modulated …

A comparative study was performed to reveal differences and relative figures of merit of
seven different calculation algorithms for photon beams when applied to inhomogeneous …

A megavoltage computed tomography (MVCT) system was developed on the University of
Wisconsin tomotherapy benchtop. This system can operate either axially or helically, and …
