AI Article Synopsis
- - The study focuses on optimizing parameters in TomoDirect (TD)-3D conformal radiation therapy for left-breast cancer patients, specifically comparing jaw width and jaw mode settings.
- - Researchers utilized a phantom to assess treatment plans, finding minimal differences in conformity and homogeneity indexes between fixed and dynamic jaw modes at different field widths.
- - The findings suggest that using dynamic jaws with a 5.0 cm field width leads to better dose delivery, reduced treatment time, and less harm to surrounding healthy tissue in breast cancer radiotherapy.
Article Abstract
It is very important to use effective parameters in the treatment plan of breast cancer patients in TomoDirect (TD)-three-dimensional conformal radiation therapy (TD-3DCRT). The objective of this study was to compare the radiation treatment plans to the parameters (jaw width and jaw mode) of TD-3DCRT for left-breast cancer. This study was conducted using the phantom, the jaw mode (fixed and dynamic) and field width (2.5 cm and 5.0 cm) were controlled to compare the TD-3DCRT treatment plans. There was small difference in the conformity index (CI) and homogeneity index (HI) values for target according to the jaw mode for each field width. As a result of observation in terms of dose, treatment time and unnecessary damage to surrounding normal organs could be minimized when dynamic jaw with a field width of 5.0 cm was used. In conclusion, we verified that the use of dynamic jaws and 5.0 cm field width was effective in left-breast cancer radiotherapy plan using TD-3DCRT.
