Proton beam therapy is a well-established medical procedure for treating certain kinds of cancer and is uniquely suited for treatment of head, neck, and eye tumors. Despite the continuous improvements in treatment plan simulations, improper tissue irradiation can occur if there is a physical shift (e.g., patient movement) in the tumor or critical organs during the irradiation process. Currently, there are no micro-implantable feedback methods to assure proper irradiation of a tumor and inform the physician of the in vivo dosage.
To address this problem, researchers in the Maharbiz Lab are working on a CMOS-based radiation detector ASIC that gives real-time dose feedback to clinicians. With the lab’s demonstration of the first-ever millimeter-sized dosimeter for single charged particle detection, safer and more effective treatment is possible via closed-loop control proton therapy. Recent work on design of the ASIC will be presented, as well as benchtop measurement results performed at the UC Davis Crocker Nuclear Lab.
