Witryna1 lut 2024 · We generated a single-beam IPO-IMPT plan for patient 1, with a primary goal of reducing LET d to heart while maintaining target coverage. Figure 4 shows dose, DADR, and LET d distributions, together with volume histograms. The target coverages for the IPO-IMPT and IMPT plans are similar. WitrynaIMRT usually consists of several treatment fields with different directions, hundreds of beam lets with modulated intensity, an advantage over 3D-CRT, whereas VMAT has advantage over IMRT due to rotating beam utilisation. VMAT has lower total MU and treatment times than IMRT and 3D-CRT, while maintaining similar dosimetric …

WitrynaThe treatment plans for IMRT and IMPT were both generated using the Treatment Planning System (TPS) of Eclipse (Varian Medical System, Inc., California, USA). The IMPT plans used two en-face beam angles and the IMPT with pencil beam weights was obtained through robust single-field optimization (SFO) technique. WitrynaIntensity-modulated radiation therapy, or IMRT, is a type of cancer treatment that uses advanced computer programs to calculate and deliver radiation directly to cancer cells from different angles. It allows people with cancer to receive higher, more effective doses of radiation while limiting damage to the healthy tissues and organs around it.

WitrynaImage-guided radiation therapy (IGRT) is the process of performing imaging before daily radiotherapy, with the intent of improving target accuracy and precision by correcting for geometric and anatomic deviations. IGRT techniques consist of planar or volumetric imaging, which allows for tighter treatment margins. Witryna24 sty 2008 · In radiotherapy of NPC patients, three-field IMPT has greater potential than nine-field IMRT with respect to tumor coverage and reduction of the integral dose to OARs and non-specific normal tissues. The practicality of IMPT in NPC deserves further exploration when this technique becomes available on wider clinical scale. Background
