Research Synopsis

  • Radiation dosimetry
  • Water calorimetry
  • Graphite probe calorimeter
  • Beam quality measurement
  • Design and development of novel clinical detectors

Research Summary:

Radiation dosimetry is an important aspect of medical physics and radiation oncology in general. It is the measurement of the amount of radiation energy delivered to a phantom or a patient.

Dr. Sarfehnia's main research interest is in design and development of novel dose detectors that can measure radiation dose accurately and directly. The detectors are commonly based on the concept of calorimetry, which attempts to measure dose by measuring the manifested minute temperature rises from radiation.

Dr. Sarfehnia's students are also looking into designing detectors capable of directly measuring radiation beam quality in a clinical setting. This is the first step toward directly measuring biological damage instead of a physical quantity called dose.
