EPID‐guided 3D dose verification of lung SBRT

Medical Physics, 2010
Purpose:To investigate the feasibility of utilizing tumor tracks from electronic portal imaging device (EPID) images taken during treatment to verify the delivered dose.Methods:The proposed method is based on a computation of the delivered fluence by utilizing the planned fluence and the tumor motion track for each field.

Characterization of EPID software for VMAT transit dosimetry

Australasian Physical & Engineering Sciences in Medicine, 2018
Dosimetry check (DC) is a commercial software that allows reconstruction of 3D dose distributions using transit electronic portal imaging device (EPID) images. In this work, we evaluated the suitability of DC software for volumetric modulated arc therapy (VMAT) transit dosimetry.

Dose‐response characteristics of an amorphous silicon EPID

Medical Physics, 2005
Electronic portal imaging devices (EPIDs) were originally developed for the purpose of patient setup verification. Nowadays, they are increasingly used as dosimeters (e.g., for IMRT verification and linac‐specific QA). A prerequisite for any clinical dosimetric application is a detailed understanding of the detector's dose‐response behavior. The aim of

TU‐A‐BRA‐01: EPID, MVCT

Medical Physics, 2007
The Mega‐Voltage Cone‐Beam CT (MVCBCT) system provides a 3D image of the patient anatomy in the actual treatment position that can be tightly aligned to the planning CT, allowing daily verification and correction of the patient position moments before the dose delivery.
