Three dimensional radiochromic detection of therapeutic radiation

Abstract

Advances in radiotherapy over the last twenty years have resulted in the ability to deliver complex therapeutic treatments. Radiation oncologists can deliver complex treatment modalities designed to maximize irradiation of the tumor mass while limiting the exposure of proximal normal tissues. The planning of the radiotherapy treatment is essential to a successful clinical outcome. Recently three-dimensional dosimetry has enabled the testing and verification of calculated therapeutic radiation protocols, in which the clinician can visualize the impact of the proposed therapy on dosimetric media simulating the tissue and tumor mass of the patient. Here in the development of a solid plastic dosimeter, which can accurately and quantitatively report the field and intensity of radiation, is discussed. This dosimeter holds great promise to assist radiation oncologists to fine-tune and validate proposed radiotherapy treatments.

“…Gel dosimeter is the only real 3D dosimeter used to measure the dose distribution in 3D [9,10]. These dosimeters can play the role of a phantom due to their water or soft tissue equivalency and thus do not perturb radiation fields [11][12][13].…”
