A study of positioning orientation effect on segmentation accuracy using convolutional neural networks for rectal cancer.
CONCLUSIONS: Orientation affects the accuracy for CTV and bladder, but has negligible effect on the femurs. The model trained from data combining both orientations performs as well as a model trained with data from the same orientation for all the organs. These observations can offer guidance on the choice of training data for accurate segmentation.
