Implantable Wireless Dosimeters for Radiation Oncology

T. Maleki, C. Son, B. Ziaie

We present the development of two radiation detectors for accurate dose monitoring in radiation oncology. The first one is a passive MEMS-based miniature ionization chamber for total accumulated dose measurement. A sensitivity of 49 kHz/Gy in a dynamic range of 30 Gy was achieved in an LC configuration. The second transducer is based on a sensitive solid-state structure that can be used in active interrogation schemes. This sensor exhibited a sensitivity of 50 k¿/Gy in a dynamic range of 20 Gy.
