Research Grants
- RADIATION THERAPY WITH ACTIVE BREATHING CONTROLJohn Wong; Fiscal Year: 2001..Clinical feasibility of treatment with ABC will also be tested on 25 patients undergoing conventional treatment by studying the reproducibility and acceptance of the procedure by the patients and the treatment personnel. ..
- An Image Guided Small Animal Radiation Research PlatformJohn Wong; Fiscal Year: 2007..The collaborative efforts are best coordinated in a Bioengineering Research Partnership (BRP). An Oversight Group is formed to evaluate the progress of the BRP, and to help identify opportunities and hypotheses for future research. ..
