P13. Partial bolus verification of patient dose via MOSFET dosimeters. D. Lightfoot Allegheny University of Health Sciences, Philadelphia, PA.

Abstract: Poster Paper presented at AAPM, Nashville, TN, 1999.Determination of Dmax using partial bolus on patients for photon irradiations led to some apparent discrepancies (~ 6%) between planned and measured doses, especially at short SSD values. It was determined that the higher dose recorded by the MOSFET under partial bolus conditions is more representative of the true patient dose.

Discrepancies were found in the treatment planning algorithms using the MOSFET and other measured values.
