WebApr 1, 2024 · With the introduction of modern sophisticated radiotherapy (RT) techniques, the significance of accuracy has increased considerably. This study evaluated the … WebImage-Guided Radiation Therapy. Image-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.

WebMar 10, 2024 · Intrafractional motion data were used from acquired pre- and posttreatment kV/kV-OIPs, as discussed previously. The treatment plans as per TPS and inter- and intrafractional errors were assessed by using the in-house software tool to generate treatment plans based on daily inter- and intrafractional variations. WebThe aims of this study were 1) to assess BH reproducibility by analysing intrafractional shifts using IF-CBCT in a cohort of liver SBRT patients and 2) to quantify the potential maximal variability in BH by using the position of the diaphragm as a surrogate.
