Witryna15 sty 2008 · Phase 1. Detailed Description: IMRT treatment uses a computer-controlled x-ray (CT) to deliver radiation beams at several different angles and strengths to deliver precise doses to the regions at risk for recurrence of breast cancer while reducing or sparing the dose to critical structures (heart, lungs) and nearby normal tissue. Witryna1 sty 2024 · The APBI-IMRT-Florence trial (NCT02104895) schedule (30 Gy in 5 fractions) might represent an appealing treatment option, being both a safe and effective partial breast irradiation schedule, with long-term reported results.

WitrynaWhen compared to the tangential plans, SIB-IMRT maintained coverage (V95%) to the left breast and lumpectomy bed without significantly increasing the left breast maximum dose. SIB-IMRT was able to reduce the lung mean dose, maximum dose, and the V20 by 55–104 cGy, 983–1298 cGy (p < 0.001), and 3.7–4.4%, respectively.

Possible benefits include increased homogeneity, faster planning time, less inter-planner variability and lower doses to organs at risk (OAR).

WitrynaIntroduction. Nasopharyngeal carcinoma (NPC) is the most common head and neck cancer in Southeast Asia. 1 Radiotherapy is the main treatment modality for NPC. With the advancement of imaging technology, the emergence of intensity-modulated radiation therapy (IMRT), and the application of concurrent chemotherapy in patients with … WitrynaIMRT breast cancer planning parameters for HI, CI, and D 2% were lower for plasticine bolus than a virtual bolus. Conclusions: Virtual bolus causes an overestimation of breast cancer radiation dosimetry. Several considerations are needed for using plasticine bolus to overcome the dosimetry decrement. INTRODUCTION

WitrynaIMRT is an advanced method of treatment planning and delivery. In contrast to 3D-CRT, IMRT uses inverse planning, meaning that target and normal tissue constraints describing the desired dose distribution are transferred to the planning software, which then uses algorithms to generate beam arrangements that best meet the objectives … WitrynaAn IMRT breast/chest wall plan WITH nodal involvement must meet the following constraints: At least 95% of the prescription dose covers at least 95% of the PTV …

Witryna21 mar 2011 · There is a good body of literature showing that inversed planned intensity modulated radiotherapy (IMRT) potentially leads to a more favourite dose distribution compared to three-dimensional planned conformal radiotherapy (3D-CRT) for the radiotherapy of the whole breast after breast conserving surgery [ 25 – 48 ].
