Introduction: The aim of this study was to assess the results of the local pre-treatment verifications of online adaptive prostate SBRT plans performed by dosimetrists METHODS AND MATERIALS: Prostate SBRT treatments are planned in our department using an online adaptive method developed and validated by our group. The adaptive plans were computed on the daily CBCT scan using the Acuros XB v. 16.

Materials And Methods: Twenty clinical of intensity-modulated (IMRT) SIMT SRS plans were reviewed. A total of 88 brain metastases were included.
Purpose: To investigate the feasibility of using the free PRIMO Monte Carlo software for independent dose check of cranial SRS plans designed with the Varian HyperArc (HA) technique.
Materials And Methods: In this study, the PRIMO Monte Carlo software v. 0.
Purpose: This study aimed to describe the feasibility of the online adaptive radiation therapy (oART) method developed at the Hospital Quirónsalud Barcelona for prostate cancer, using a standard C-arm linear accelerator (linac) and without the support of artificial intelligence.
Methods And Materials: The first 18 patients treated at the Hospital Quirónsalud Barcelona with the developed oART method were included. An ultrahypofractionated radiation therapy scheme consisting of 7 × 6.
Article Synopsis
- The study evaluates the accuracy of the VIPER software, which reconstructs a 3D dose distribution for radiosurgery, by comparing it with a standard Monte Carlo simulation.
- It involves testing several treatment plans using a 6 MV photon beam and assessing the results with ionization chambers and radiochromic films for accurate dose measurements.
- Findings indicate that VIPER is a reliable tool for verifying multiple-target stereotactic radiosurgery plans, achieving high gamma passing rates and requiring no setup time on the linear accelerator (linac).
Aim: To investigate whether the target-isocenter deviations reported by a conventional Winston-Lutz (WL) test actually reflect the shifts of the measured prescription isodose line with respect to the target.
Background: A conventional WL test uses a metallic ball as a target that aims at several fields. But this test does not report information on the accuracy of the delivery in terms of dose.
Purpose: To evaluate the spatial accuracy of a frameless cone-beam computed tomography (CBCT)-guided cranial radiosurgery (SRS) using an end-to-end (E2E) phantom test methodology.
Methods And Materials: Five clinical SRS plans were mapped to an acrylic phantom containing a radiochromic film. The resulting phantom-based plans (E2E plans) were delivered four times.
