Annual international conference of the IEEE Engineering in Medicine and Biology Society (EMBC)
作者: E.N. Donskoy Sarov N. Novgorod Region Russian Federation Nuclear Center All-Russian Scientific Research Institute of Experimental Physics Russia
At 3D dosimetry planning in radiation therapy, point flux PL-estimators are convenient for Monte Carlo dose calculations in a human body. The method of construction of PL-estimators is based on a property of local opt... 详细信息

作者: J.M. Kapatoes G. Olivera P. Reckwerdt H. Keller J. Balog T.R. Mackie Department of Medical Physics University of Wisconsin Madison WI USA Tomotherapy Inc. Middleton WI USA
A consequence of the advent of intensity modulated radiation therapy (IMRT) is the presence of large dose gradients surrounding the tumor, and the regions at risk (RAR's) near the tumor. Unlike standard radiothera... 详细信息
