WE‐E‐108‐03: Relative Biological Effectiveness (RBE) of Protons in Pristine Bragg Peaks
Medical Physics, 2013Purpose: Quantify spatial variations in proton RBE in the plateau region and near the distal edge of pristine Bragg peaks. Methods: The linear energy transfer (LET) and dosimetric characteristics of pristine Bragg peaks were simulated for 30 and 200 MeV proton beams using MCNPX Version 2.7.0.

Intraoperative radiation therapy (IORT) with low-energy x-rays is used to treat the tumor bed during breast-conserving surgery. The purpose was to determine the relative biologic effectiveness (RBE) of 50-kV x-rays for inactivation of cells irradiated in a tumor-bed phantom.The RBE was determined for clonogenic inactivation of human tumor and normal ...

Proton therapy treatments are based on a proton RBE (relative biological effectiveness) relative to high-energy photons of 1.1. The use of this generic, spatially invariant RBE within tumors and normal tissues disregards the evidence that proton RBE varies with linear energy transfer (LET), physiological and biological factors, and clinical endpoint ...

Relative biological effectiveness (RBE) of heavy ions (O+8) for producing retinal lesions.
Aviation, space, and environmental medicine, 1977The relative biological effectiveness (RBE) for oxygen ions (250 MeV/nucleon) for producing an ischemic retinal lesion in the rhesus monkey has been shown to be greater than 10. The RBE concept and the use of the standard methodology is discussed with respect to other published reports.

Human prostate tumors are known to be good candidates for neutron therapy. The Dunning rat prostate tumor system R3327 was found in many studies to be an excellent model for human prostate tumors. There is still a paucity of studies on the response of the Dunning tumors to fast neutrons. Tumors of the R3327-HI subline are moderately well differentiated
