Uniform B-Splines for the VTK Imaging Pipeline
Uniform B-splines are used widely in image processing because they provide maximal smoothness compared to any other piecewise polynomial of the same degree and support. This paper describes VTK classes for performing two functions: image interpolation via [...]

An Open-Source Solution for Interactive Acquisition, Processing and Transfer of Interventional Ultrasound Images
No opinion
Ultrasound has become a very important modality in image-guided therapy. At present, however, the collection, synchronization and transfer of ultrasonic images are more cumbersome than necessary. This paper presents a reusable solution to these problems. We [...]

An open-source real-time ultrasound reconstruction system for four-dimensional imaging of moving organs
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 [...]

Simulink Libraries for Visual Programming of VTK and ITK
We have created open-source Simulink block libraries for ITK and VTK that allow pipelines for these toolkits to be built in a visual, drag-and-drop style within MATLAB. Each block contains an instance of an ITK or VTK class. Any block connections and [...]

Visual Programming of VTK Pipelines in Simulink
We have created a wrapper package named SimVTK that allows VTK, and third-party classes derived from VTK classes, to be seamlessly integrated with MATLAB's Simulink interface. Our package generates a loadable Simulink module for each VTK class, which is then [...]

IGSTK: Development Process and Project Management Best Practices for an Open Source Software Toolkit for Image-Guided Surgery Applications
Open source technologies are increasing in popularity for software development. Many open source projects rely on skilled development teams whose members are distributed throughout the world. Often, agile development methods are employed by these teams, as [...]

IGSTK: A State Machine Architecture for an Open Source Software Toolkit for Image-Guided Surgery Applications
The Image-Guided Surgery Toolkit (IGSTK) is an Open Source software project being developed under NIH/NIBIB funding. The toolkit will provide a common platform for implementing image-guided surgery applications and for fostering research in the field. The [...]
