Investigating the shortcomings of the Flow Convergence Method for quantification of Mitral Regurgitation in a pulsatile in-vitro environment and with Computational Fluid Dynamics

Robin Leister, Roger Karl, Lubov Stroh +12

The flow convergence method includes calculation of the proximal isovelocity surface area (PISA) and is widely used to classify mitral regurgitation (MR) with echocardiography. It…

mvHOTA: A multi-view higher order tracking accuracy metric to measure spatial and temporal associations in multi-point detection

Lalith Sharan, Halvar Kelm, Gabriele Romano +3

Multi-point tracking is a challenging task that involves detecting points in the scene and tracking them across a sequence of frames. Computing detection-based measures like the F-…

Comparison of Depth Estimation Setups from Stereo Endoscopy and Optical Tracking for Point Measurements

Lukas Burger, Lalith Sharan, Samantha Fischer +7

To support minimally-invasive intraoperative mitral valve repair, quantitative measurements from the valve can be obtained using an infra-red tracked stylus. It is desirable to vie…

Point detection through multi-instance deep heatmap regression for sutures in endoscopy

Lalith Sharan, Gabriele Romano, Julian Brand +4

Purpose: Mitral valve repair is a complex minimally invasive surgery of the heart valve. In this context, suture detection from endoscopic images is a highly relevant task that pro…

Mutually improved endoscopic image synthesis and landmark detection in unpaired image-to-image translation

Lalith Sharan, Gabriele Romano, Sven Koehler +4

The CycleGAN framework allows for unsupervised image-to-image translation of unpaired data. In a scenario of surgical training on a physical surgical simulator, this method can be…

Heatmap-based 2D Landmark Detection with a Varying Number of Landmarks

Antonia Stern, Lalith Sharan, Gabriele Romano +5

Mitral valve repair is a surgery to restore the function of the mitral valve. To achieve this, a prosthetic ring is sewed onto the mitral annulus. Analyzing the sutures, which are…
