TL;DR: The principal takeaway from VerSe: the performance of an algorithm in labelling and segmenting a spine scan hinges on its ability to correctly identify vertebrae in cases of rare anatomical variations.
Book ChapterDOI
Landmark-Free Statistical Shape Modeling Via Neural Flow Deformations
TL;DR: Casp et al. as mentioned in this paper proposed FlowSSM, a shape model that learns shape variability without requiring dense correspondence between training instances, based on a hierarchy of continuous deformation flows which are parametrized by a neural network.
Proceedings Article
Learning Shape Reconstruction from Sparse Measurements with Neural Implicit Functions
TL;DR: In this paper , the authors proposed a method for high-resolution shape reconstruction from sparse measurements without relying on high resolution ground truth for training, which is based on neural implicit shape representations and learns a continuous shape prior only from highly anisotropic segmentations.
Journal Article
A for-loop is all you need. For solving the inverse problem in the case of personalized tumor growth modeling
Ivan Ezhov,Marcel Rosier,Lucas Zimmer,Florian Kofler,Suprosanna Shit,Johannes C. Paetzold,Kevin Scibilia,Leon Maechler,Katharina Franitza,Tamaz Amiranashvili,Martin J. Menten,Marie-Christin Metz,Sailesh Conjeti,Benedikt Wiestler,Bjoern H. Menze +14 more
TL;DR: In this article , the authors proposed a method compressing complex traditional strategies for solving an inverse problem into a simple database query task, which can achieve one order speedup compared to existing approaches for solving the inverse problem.
Journal ArticleDOI
A Domain-specific Perceptual Metric via Contrastive Self-supervised Representation: Applications on Natural and Medical Images
Hongwei Li,Chinmay Prabhakar,Suprosanna Shit,Johannes C. Paetzold,Tamaz Amiranashvili,Jianguo Zhang,Daniel Rueckert,Juan Eugenio Iglesias,Benedikt Wiestler,Bjoern H. Menze +9 more
TL;DR: In this article , contrastive self-supervised representation (CSR) is used as a metric to measure perceptual similarity between two images in the medical domain, and CSR can significantly improve the image quality in two image synthesis tasks.
