RSC: Gel dosimetry as a tool for clinical implementation of image-guided radiotherapy

Abstract: The implementation of new image-guided radiotherapy (IGRT) treatment techniques requires the development of new quality assurance (QA) methods including geometric and dosimetric validation of the applied dose in 3D. Polymer gels (PG) provide a promising tool to perform such tests. However, to be used in a large variety of clinical applications, the PG must be flexibly applicable. In this work, we present a variety of phantoms used in clinical routine to perform both hardware and workflow tests in IGRT. This in… Show more

“…In another study, Elter et al (2022) used (i) a cylindrical motion phantom and (ii) a porcine lung phantom equipped with PG dosimeters to test IFMM by an MR-Linac system. Dose was delivered while the phantoms were simulating a breathing pattern and the PG container was tracked by the MR Imaging system.…”

“…[98]). Some specific developments and applications for E2E QA to evaluate specific clinical treatment protocols are referenced in Table 1 below (which presents a list of vendors that supply various commercial tools and services to aid in-house E2E testing) and in the most recent IC3Ddose proceedings from the virtual meeting in 2021 [99][100][101][102][103]. These and other [21,53,96,[104][105][106][107][108][109][110][111][112] clinical reports span a range of investigations into the feasibility of RT E2E testing, nonetheless they do make some common observations.…”

“…Irradiation-induced polymerization of BANG gels affects the mobility of surrounding water molecules and, hence, the spin-spin relaxation (R2) rate of NMR. Polymer dosimeters are suitable for quality assurance in radiotherapy [37][38][39]. Recently, Kudrevicius et al used modified PAG dosimeters for quality assurance in stereotactic radiosurgery treatments.…”
