Particle-Based Shape Modeling for Arbitrary Regions-of-Interest

no code implementations29 Dec 2023 Hong Xu, Alan Morris, Shireen Y. Elhabian

We propose an extension to \particle-based shape modeling (PSM), a widely used SSM framework, to allow shape modeling to arbitrary regions of interest.

Spatiotemporal Cardiac Statistical Shape Modeling: A Data-Driven Approach

no code implementations6 Sep 2022 Jadie Adams, Nawazish Khan, Alan Morris, Shireen Elhabian

Clinical investigations of anatomy's structural changes over time could greatly benefit from population-level quantification of shape, or spatiotemporal statistic shape modeling (SSM).

Statistical Shape Modeling of Biventricular Anatomy with Shared Boundaries

no code implementations6 Sep 2022 Krithika Iyer, Alan Morris, Brian Zenger, Karthik Karanth, Benjamin A Orkild, Oleksandre Korshak, Shireen Elhabian

This paper presents a general and flexible data-driven approach for building statistical shape models of multi-organ anatomies with shared boundaries that capture morphological and alignment changes of individual anatomies and their shared boundary surfaces throughout the population.

Deep Learning for End-to-End Atrial Fibrillation Recurrence Estimation

no code implementations30 Sep 2018 Riddhish Bhalodia, Anupama Goparaju, Tim Sodergren, Alan Morris, Evgueni Kholmovski, Nassir Marrouche, Joshua Cates, Ross Whitaker, Shireen Elhabian

In this paper, we propose a machine learning approach that uses deep networks to estimate AF recurrence by predicting shape descriptors directly from MRI images, with NO image pre-processing involved.
