Dosimetric Comparative Analysis of Volumetric Modulated Arc Therapy and Intensity-Modulated Radiation Therapy in Cervical Cancer
نویسندگان
چکیده
Objective: To carry out dosimetric comparison between volumetric modulated arc therapy (VMAT) and intensity-modulated radiation (IMRT) in cervical cancer. Methods: 50 postoperative cancer patients were included this study. The admitted for treatment from January 2021 to 2022. VMAT IMRT plans designed each patient analyze the dose distribution target area of two techniques. Results: Comparing monitor unit single (638.21 ± 116.21 MU) time (143.21 23.14 s) observation group (932.14 74.11 (223.14 17.26 control group, there was significant difference (P < 0.05); also 0.05) normal tissue (bladder rectum) that group. Conclusion: is more effective cancer, it has a certain protective effect on tissues can reduce dose.

Intensity modulated radiation therapy versus volumetric intensity modulated arc therapy
The advanced developments in external beam radiation therapy (EBRT) over the past few decades have improved dose conformity to the target while minimizing dose to the surrounding organs at risk (OAR). Intensity modulated radiation therapy (IMRT) and volumetric modulated arc therapy (VMAT) are two commonly used EBRT techniques to treat cancer. In sliding window (SW) or dynamic IMRT, each radiati...

Dosimetric comparisons between RapidArc (RA) and conventional Intensity-Modulated Radiation Therapy (IMRT) techniques for nasopharyngeal carcinoma (NPC) were performed to address differences in dose coverage of the target, sparing of organs-at-risk (OARs), delivery of monitor units (MUs) and time, to assess whether the RA technique was more beneficial for treatment of NPC. Eight NPC patients (S...
