Evaluation of two automated treatment planning techniques for multiple brain metastases using a single isocenter.

Journal Article J Radiosurg SBRT · 2022 Two automated treatment planning techniques were evaluated for multiple brain metastases using a single isocenter. One technique is knowledge-based planning (KBP) using a stereotactic radiosurgery (SRS) model in Eclipse treatment planning system (TPS); and ... Link to item Cite

Technical Note: Investigation of the dosimetric impact of stray radiation on the Common Control Unit of the IBA Blue Phantom2.

Journal Article J Appl Clin Med Phys · January 2020 PURPOSE: This technical note aims to investigate the dosimetric impact of stray radiation on the Common Control Unit (CCU) of the IBA Blue Phantom2 and the measured beam data. METHODS: Three CCUs of the same model were used for the study. The primary test ... Full text Link to item Cite

TU‐E‐108‐03: Optimization of the Beam‐On Latency of An Elekta Linac in the Delivery of Gated VMAT

Conference Medical Physics · January 1, 2013 Purpose: To optimize the beam‐on latency of an Elekta linac in delivering gated VMAT. Methods: Step‐wise optimization was performed using a pre‐clinical gating interface developed by Elekta. Phantom studies were performed where surface motion was simulated ... Full text Cite

An automated method for comparing motion artifacts in cine four-dimensional computed tomography images.

Journal Article J Appl Clin Med Phys · November 8, 2012 The aim of this study is to develop an automated method to objectively compare motion artifacts in two four-dimensional computed tomography (4D CT) image sets, and identify the one that would appear to human observers with fewer or smaller artifacts. Our p ... Full text Open Access Link to item Cite

SU‐E‐T‐343: Respiratory‐Gated Volumetric Modulated Arc Therapy for Lung SBRT with an Elekta Digital Accelerator: A Pre‐Clinical Evaluation

Conference Medical Physics · January 1, 2012 Purpose: To evaluate the machine‐delivery capabilities and dosimetric accuracy of respiratory‐gated VMAT delivered with an Elekta digital accelerator. Method and Materials: Three lung patients previously treated with SBRT using un‐gated 6 MV VMAT were used ... Full text Cite

TU‐E‐BRC‐09: An Automated Scoring Method for Motion Artifacts in Cine Four‐Dimensional Computed Tomography Images

Conference Medical Physics · January 1, 2011 Purpose: The aim of this work is to develop an automated method to objectively score the severity of image artifacts in four‐dimensional (4D) computed tomography (CT).

Method and Materials: Imaging artifacts in 4D CT have been ... Full text Cite

Dose verification of 2 targets simultaneously for single-isocenter stereotactic radiation therapy and radiosurgery plans.

Journal Article Med Dosim Most of conventional 2-dimensional (2D) methods verify dose of multiple targets separately one-by-one for Single-isocenter Multiple-target (SIMT) brain plans, which are inefficient and sub-optimal. This study presented a practical method to verify the dose ... Full text Link to item Cite
