Using the Polar Transform for Efficient Deep Learning-Based Aorta Segmentation in CTA Images Interuniversity Microelectronics Centre
Medical image segmentation often requires segmenting multiple elliptical objects on a single image. This includes, among other tasks, segmenting vessels such as the aorta in axial CTA slices. In this paper, we present a general approach to improving the semantic segmentation performance of neural networks in these tasks and validate our approach on the task of aorta segmentation. We use a cascade of two neural networks, where one performs a ...
