Commissioning of a motion management system for a 1.5T Elekta Unity MR-Linac: A single institution experience.

ABSTRACT:

Purpose

This work describes a single institution experience of commissioning a real-time target tracking and beam control system, known as comprehensive motion management, for a 1.5 T Elekta MR-Linac.

Methods

Anatomical tracking and radiation beam control were tested using the MRI^4D Quasar motion phantom. Multiple respiratory breathing traces were modeled across a range of realistic regular and irregular breathing patterns ranging between 10 and 18 breaths per minute. Each of the breathing traces was used to characterize the anatomical position monitoring (APM) accuracy, and beam latency, and to quantify the dosimetric impact of both parameters during a respiratory-gated delivery using EBT3 film dosimetry. Additional commissioning tasks were performed to verify th
