Gy to 72 Gy (Figure 1D). The supraclavicular region typically received 50 Gy in 25 fractions
(2 Gy/fx) with an anterior field (Figure 1E). The middle block in Figure 1E was to protect the …

Abstract 3D-CRT is an advanced radiotherapy technique that minimizes radiation therapy
side effects. It delivers high-energy radiation beams from multiple angles, precisely targeting …

Aim To compare intensity modulated radiotherapy with simultaneous integrated boost (IMRT-
SIB) and a 3-dimensional conformal parotid gland-sparing radiotherapy (ConPas 3D-CRT) …

Background: Multimodality treatment is required for the management of head and neck
cancer. Functional impairment and toxicities associated with surgery and radiation …

Introduction: Due to the effect of radiation on both the tumor and the surrounding normal
tissues, the side effects of radiation in normal tissues are expected. One of the important …

BackgroundThis work aims to compare the dosimetric performance of three-dimensional
conformal radiotherapy (3D-CRT), a relatively available technique in developing countries …

前列腺癌是我国老年男性中常见的恶性肿瘤之一, 放射治疗是其主要的治疗手段.
