Building a 3D Dosimeter for Medical Applications

Ugur Akgun

A 3-D dosimeter fills the need for treatment plan and delivery verification required by every modern radiation-therapy method. The Akgun group is working on developing a water-equivalent solid 3-D dosimeter that is based on a novel radiation-hard scintillating material. In summer of 2022, the group will work on optimizing a new polystyrene-based scintillating material and build a second-generation prototype.

Scintillating bars produced by Akgun group for the first-generation prototype.

After producing the scintillating bars, we will test the light production capabilities and radiation hardness of the scintillating material. We will then build a prototype and test it with an X-Ray beam at the Ohio State Medical School.

First-generation prototype built by students

A 3-D dose distribution be reconstructed by a neural network specifically trained for this prototype. The detector will be simulated using Gate software and the data will be used for training an Artificial Neural Network. The machine learning method will be applied on test beam data to reconstruct the 3D dose distribution.
