Fully automated brain resection cavity delineation for radiation target volume definition in glioblastoma patients using deep learning
2020
Radiation Oncology
Preserved Fulltext
We evaluated the segmentation method in terms of Dice coefficient (DC) and estimated volume measurements. ...
We did not detect a statistically significant difference of the measured RC volumes for the different raters and the automated method (Kruskal-Wallis test: chi-square = 1.46, p = 0.69). ...
Fully automatic segmentation, where no interaction of the user is required, has the potential to substantially limit the time for target volume and OAR definition. ...
