Detector Development

Mission

The detector development group works to build novel radiation detectors to solve clinical problems.  We use a mix of computer simulations lab-based tests and clinical simulations to develop precise and easy use detectors that can be easily implemented in clinical practice.

Dosimetry Detectors

Dosimetry is the practice of quantitatively determining the energy deposited in a medium by ionizing radiation. The major challenge in radiotherapy is to deliver and quantify an accurate dose of radiation to the tumor. Several dosimetry techniques are available to measure the radiation dose, but they have limitations. In particular, the non-tissue equivalence of the detector housing/material and the sensitive volume leads to perturbations of the radiation fluence and necessitates correction factors. Another constraint placed on conventional dosimetry techniques is the limited resolution. Currently, there are many ongoing research projects regarding detector development for quality assurance and in-vivo dosimetry in radiotherapy.

Imaging Detector

Dynamic positron emission tomography is a nuclear medicine imaging technique providing functional images for organs of interest with applications in oncology, cardiology, and drug discovery. This technique requires the acquisition of the time-course arterial plasma activity concentration, called the arterial input function, which is normally acquired invasively via arterial blood sampling. Currently, we are developing a radiation detector to measure the arterial input function non-invasively.
