- Abstract: The automatic segmentation of kidney, kidney tumor and kidney cyst on
Computed Tomography (CT) scans is a challenging task due to the indistinct
lesion boundaries and fuzzy texture. Considering the large range and unbalanced
distribution of CT scans' thickness, 2.5D ResUnet are adopted to build an
efficient coarse-to-fine semantic segmentation framework in this work. A set of
489 CT scans are used for training and validation, and an independent
never-before-used CT scans for testing. Finally, we demonstrate the
effectiveness of our proposed method. The dice values on test set are 0.954,
0.792, 0.691, the surface dice values are 0.897, 0.591, 0.541 for kidney, tumor
and cyst, respectively. The average inference time of each CT scan is 20.65s
and the max GPU memory is 3525MB. The results suggest that a better trade-off
between model performance and efficiency.

We propose a weakly-supervised deep learning framework that preserves the rigidity and the volume of each vertebra while maximizing the accuracy of the registration.
We specifically design these losses to depend only on the CT label maps since automatic vertebra segmentation in CT gives more accurate results contrary to MRI.
Our results show that adding the anatomy-aware losses increases the plausibility of the inferred transformation while keeping the accuracy untouched.
