Over the past three decades several randomized trials have enabled evidence-based
practice for patients presenting with limited brain metastases. These trials have focused on …

Task Group 101 of the AAPM has prepared this report for medical physicists, clinicians, and
therapists in order to outline the best practice guidelines for the external‐beam radiation …

Stereotactic body radiotherapy (SBRT) involves the treatment of extracranial primary tumors
or metastases with a few, high doses of ionizing radiation. In SBRT, tumor kill is maximized …

The American Association of Physicists in Medicine (AAPM) is a nonprofit professional
society whose primary purposes are to advance the science, education, and professional …

Purpose To identify an optimal margin about the gross target volume (GTV) for stereotactic
radiosurgery (SRS) of brain metastases, minimizing toxicity and local recurrence. Methods …

Objectives This study compares the dosimetry and efficiency of two modern radiosurgery
[stereotactic radiosurgery (SRS)] modalities for multiple brain metastases [Gamma Knife …

radiosurgery for multiple intracranial targets (SIRMIT) including increased sensitivity to …

PURPOSE: Flattening filter–free (FFF) beams with higher dose rates and faster delivery are
now clinically available. The purpose of this planning study was to compare optimized non …

Purpose: Spine SBRT requires treatment plans with steep dose gradients and tight limits to
the cord maximal dose. A new dual-layer staggered 1-cm MLC in Halcyon™ treatment …

Previous work demonstrated improved dosimetry of single isocenter volumetric modulated
arc therapy (VMAT) of multiple intracranial targets when they are located≤ 4 cm from …
