Article Synopsis
- The study focused on improving the efficiency of outlining organs at risk (OARs) during intensity-modulated radiation therapy by automating the contouring process using atlas-based auto-segmentation (ABAS).
- Results showed that automation reduced the average time for contour delineation from 57 minutes to 29 minutes, while some OARs still need further geometric accuracy improvements.
- Overall, the ABAS model successfully minimized both work time and software operations, indicating potential for even greater efficiency with enhancements to contour accuracy.
Article Synopsis
- * Researchers analyzed data from 142 patients who received high-dose-rate brachytherapy, calculating effective dose rates and biologically equivalent doses for rectal volumes exposed to certain doses.
- * Results showed that higher effective dose rates and doses correlated with a significant increase in late rectal complications, identifying specific dose metrics as independent predictors for these complications.
