PURPOSE The purpose of this study was to identify a more suitable boost plan for simultaneously integrated boost scheme in patients with breast cancer by comparing among 3 types of whole-breast irradiation plus tumor bed boost plans. METHODS Twenty patients who received radiotherapy following breast-conserving surgery for early breast cancer were enrolled in this study. We performed 1 type of...

The purpose of this investigation was to evaluate the potential dosimetric benefits of a two-phase adaptive intensity-modulated radiotherapy (IMRT) protocol for patients with locally advanced nasopharyngeal cancer (NPC). A total of 17 patients with locally advanced NPC treated with IMRT had a second computed tomography (CT) scan after 17 fractions in order to apply and continue the treatment wi...

The book written by seventeen experts in the field of rangeland management, this compilation of essays brings to light the latent issues concerning this subject to readers all over the globe. Though technical approaches can address some issues, social processes ultimately prevent the balancing of these matters. Socio-economic and political institutions are often a stumbling block for improving ...

The aim of this study was to compare lateral photon-electron (LPE), helical tomotherapy (HT), and volumetric-modulated arc therapy (VMAT) plans for total scalp irradiation. We selected a single adult model case and compared the dosimetric results for the three plans. All plans mainly used 6-MV photon beams, and the prescription dose was 60 Gy in 30 fractions. First, we compared the LPE, HT and ...

PURPOSE To investigate the possibility of using a single spot scanning proton beam to treat superficial lesions. METHODS A cylindrical phantom with a simulated superficial target (it seated 0.5-4cm depth from the surface, volume: 270cm3 ) was created in Eclipse treatment planning system. Three proton plans were generated: (a) a single AP uniform scanning beam with aperture and range compensat...

The Computer Vision Laboratory at the University of Maryland is designing and de:reloping a vision system for autonomous ground navigation. Our approach to visual navigation segments the task into three levels called long range, intermediate range and short range navigation. At the long range, one would first generate a plan for the day's outing, identifying the starting location, the goal, and...
