Professional Focus

Dr. Chuang is the primary physicist responsible for treatment planning, quality assurance and supervision of daily Cyberknife treatments. She also shares the responsibility of overseeing and planning for IMRT treatments, as well as planning and treatment for HDR Brachytherapy when needed.

Her main research interest involves the study of patient motion using on-line imaging, including intra- and inter-fractional patient motion for head and neck IMRT treatment, and more recently, respiratory motion and its effects on treatments of lung and liver cancers. She has also been involved heavily in investigation and implementation of various new technologies for clinical quality assurance, such as the use of MOSFET for routine IMRT QA measurements, Computed Radiography (CR) system for daily portal imaging, and calibration of amorphous silicon electronic portal imaging for exit beam dosimetry. She is currently investigating the CIRS Dynamic Motion Anthropomorphic Phantom for quality assurance testing of respiratory tracking/compensated radiation treatments. She is also in the process of facilitating a research collaboration with Calypso Medical Technologies, Inc., to study the feasibility of using its invention for respiratory gated radiotherapy on Siemens linear accelerators.
