Time-resolved dosimetric verification of respiratory-gated radiotherapy exposures using a high-resolution 2D ionisation chamber array
The aim of this work was to track and verify the delivery of respiratorygated irradiations, performed with three versions of TrueBeam linac, using a novel phantom arrangement that combined the OCTAVIUS® SRS 1000 array with a moving platform. The platform was programmed to generate sinusoidal motion of the array. This motion was tracked using the real-time position management (RPM) system and fo...

متن کاملHigh resolution ion chamber array delivery quality assurance for robotic radiosurgery: Commissioning and validation.
PURPOSE High precision radiosurgery demands comprehensive delivery-quality-assurance techniques. The use of a liquid-filled ion-chamber-array for robotic-radiosurgery delivery-quality-assurance was investigated and validated using several test scenarios and routine patient plans. METHODS AND MATERIAL Preliminary evaluation consisted of beam profile validation and analysis of source-detector-d...
متن کاملSU-E-T-415: An Ionization Chamber Array with High Spatial Resolution for External Beam Radiotherapy.
PURPOSE To characterize an ionization chamber array technology with high spatial resolution and high charge collection efficiency for external beam radiotherapy. METHODS The prototype under test is a linear array of air vented ionization chambers developed by IBA Dosimetry, consisting of 80 pixels with 3.5mm spatial resolution and 4mm3 sensitive volume. The detector was characterized in a pla...
