The latency of each panel type was determined by averaging the results of two panels of the same type. Geometric correction was achieved by computing leaf positions with respect to the projected isocenter position as a function of gantry angle. This was determined by averaging the central axis position of fields at two collimator positions of 90° and 270°. The radiological to physical leaf end position was determined by comparison of the measured gap with that determined using a feeler gauge. The radiological to physical leaf position difference was found to be 0.1 mm. With geometric and latency correction, the proposed method was found to be improve the ability to detect dynamic MLC positions from 1.0 to 0.2 mm for all leaves. Latency and panel residual geometric error correction improve EPID-based MLC position measurement. These improvements provide for the first time a trajectory log QA procedure.]]> Tue 15 Nov 2022 10:14:54 AEDT ]]> Beam focal spot intrafraction motion and gantry angle dependence: A study of Varian linac focal spot alignment. https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:48311 Tue 14 Mar 2023 14:48:42 AEDT ]]> Clinical target volume delineation quality assurance for MRI-guided prostate radiotherapy using deep learning with uncertainty estimation https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:51626 Tue 12 Sep 2023 15:40:55 AEST ]]> Beam focal spot position: the forgotten linac QA parameter.

Sampling patients for generating the control limits were limited to 100 patients. Whilst the quantitative results are specific to the clinical techniques and equipment used, the described method is generally applicable to IMRT and VMAT treatment QA. Whilst more work is required to determine the level of clinical significance, the authors have demonstrated the capability of the method for both treatment specific QA and continuing quality improvement. Practical implications: The proposed method is a valuable tool for assessing the accuracy of treatment delivery whilst also improving treatment quality and patient safety. Originality/value: Assessing in vivo EPID dosimetry with SPC can be used to improve the quality of radiation treatment for cancer patients.]]> Thu 28 Oct 2021 12:37:07 AEDT ]]> VMAT linear accelerator commissioning and quality assurance: dose control and gantry speed tests https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:27239 Thu 24 Sep 2020 12:32:14 AEST ]]> Co-operative education, standards and accreditation frameworks in Australia: an overview of gaps and opportunities https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:37766 Thu 06 May 2021 13:43:00 AEST ]]> SEAFARER – A new concept for validating radiotherapy patient specific QA for clinical trials and clinical practice: SEAFARER - sensitivity of patient specific quality assurance, PSQA https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:52206 5% increase in spinal cord dose relative to the original plans.
