Cubic and Hermite splines for VTK
No opinion
A cubic spline is a spline where each curve is defined by a third-order polynomial, while a Hermite spline has each polynomial specified in Hermite form, being computed using tangent information as well as the position of the points. We propose two new [...]

Flexible architecture and modularity requirements for image guided cardiovascular surgeries
No opinion
Research and development of image guided surgery techniques requires software that provides a high degree of flexibility, with easy access to reliable functionality for common tasks. The goal of this paper is to highlight this claim in the context of image [...]

An open-source real-time ultrasound reconstruction system for four-dimensional imaging of moving organs
starstarstarstarstar
Four-dimensional imaging is a necessary step in computer-assisted interventions (CAI) performed on moving surgical targets, such as those located within the beating heart or influenced by respiratory motion. Ultrasound (US) is often the best imaging modality [...]

Multi-Atlas-based Segmentation with Hierarchical Max-Flow
No opinion
This study investigates a method for brain tissue segmentation from 3D T1 weighted (T1w) MR images via convex relaxation with a hierarchical ordering constraint. It employs a multi-atlas-based initialization from 5 training images and is tested on 12 T1w MR [...]
