introduction: multiple fields and presence of heterogeneities create complex dose distributions that need three dimensional dosimetry. in this work, we investigated mr-based magic gel dosimetry as a three-dimensional dosimetry technique to measure the delivered dose to bladder and rectum in prostate radiation therapy. materials and methods: a heterogeneous slab phantom including bones was made....

Abstract In the clinic, routine quality assurance tests ensure proper functioning of each individual aspect a radiation therapy treatment delivery. However, these may not guarantee an accurate this work, we present design and application head phantom (using 3D printing technology) developed for end-to-end stereotactic brain metastases, coupled with inserts ion chamber, film gel dosimeters. The ...

introduction patient set-up optimization is required in radiotherapy to fill the accuracy gap between personalized treatment planning and uncertainties in the irradiation set-up. in this study, we aimed to develop a new method based on neural network to estimate patient geometrical setup using 4-dimensional (4d) xcat anthropomorphic phantom. materials and methods to access 4d modeling of motion...
