A simulation of tumor removal was performed, followed by irradiation of the bed and measurement of absorbed doses with radiochromic films. Materials and Methods: Low-energy X-ray intraoperative radiotherapy (IORT) was used for irradiation. A computed tomography study was performed at each site and the absorbed doses calculated by the treatment planning system, as well as absorbed doses with radiochromic films, were studied. Results: The absorbed doses in the organs at risk (OAR) were evaluated in each case, obtaining maximum doses within the tolerance limits. The absorbed doses in the target were verified and the deviations were <1%. Conclusions: These tests demonstrated that this comprehensive procedure is a reproducible quality assurance tool which allows continuous assessment of the dosimetric and geometric accuracy of clinical brain IORT treatments. Furthermore, the absorbed doses measured in both target and OAR are optimal for these treatments. info:eu-repo/semantics/openAccess by-nc-sa https://creativecommons.org/licenses/by-nc-sa/4.0/deed.es 0.22 2023 Radiology, Nuclear Medicine and Imaging 2023 Q4 Biophysics 2023 Q4 1.1 2023 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Ibáñez-Carreras, Reyes García-Barrios, Alberto Universidad de Zaragoza (orcid)0000-0001-5560-3771 Castro-Moreno, Raquel González-Rodríguez, Andrea Sánchez-Casi, Marta Campos-Boned, Arantxa Gandía-Martínez, Almudena Font-Gómez, José Antonio Universidad de Zaragoza (orcid)0000-0003-4732-7409 Jiménez-Puertas, Sara Villa-Gazulla, David Díez-Chamarro, Javier Hernández-Hernández, Mónica González-Pérez, Víctor Cisneros-Gimeno, Ana Isabel Universidad de Zaragoza (orcid)0000-0002-5494-343X 1011 770 Universidad de Zaragoza Dpto.
