Abstract
Radiation plays a crucial role in healthcare for both diagnostics and treatment. From imaging bones and organs to fighting cancer, ensuring the right dose at the right location is critical to minimize harm to healthy tissues surrounding the target area. This presentation introduces a novel solution for dose monitoring: RAdiation Dosimeters made from large arrays of Organic Field-Effect Transistors (RAD-OFETs). These dosimeters conform to the body, enabling high-resolution, real-time dose measurements directly on the skin. Unlike existing methods, they require minimal data processing and mimic tissue absorption, providing highly accurate readings. I will discuss the detection mechanism, sensor sensitivity, and 2D dose mapping during radiation therapy. The results reveal non-uniformities, with higher doses concentrated near the beam center. This information is invaluable for optimizing radiation treatment plans, allowing doctors to maximize target dose while minimizing damage to healthy tissue, hence leading to safer and more effective treatments for patients.
