Computational radiation dosimetry for patients undergoing diagnostic and therapeutic radiation procedures


Shady Grove Room 2E 908


Organ dose received by patients in diagnostic and therapeutic radiation procedures is one of the key components in epidemiological studies of radiation-related late effects.  There are two ways to determine radiation organ doses to patients in medical exposure: measurement and calculation.  Since measurement is generally expensive and requires substantial man-hour, computational approach coupling human phantoms and Monte Carlo radiation transport method have been heavily used for medical dosimetry.  This talk will present the latest developments in dosimetry method for patients undergoing computed tomography and radiation treatment, and the applications to epidemiological studies.
