PURPOSE To assess the feasibility of the use of preprocedural imaging for guide wire, catheter, and needle navigation with electromagnetic tracking in phantom and animal models. MATERIALS AND METHODS An image-guided intervention software system was developed based on open-source software components. Catheters, needles, and guide wires were constructed(More)
The Image-Guided Software Toolkit (IGSTK: pronounced IGstick) is a high-level opensource component based software toolkit. The toolkit is currently under development and is intended to make it easy for researchers to prototype and develop image-guided surgery applications. The toolkit has been used to develop an example application incorporating(More)
Modular and flexible software components can be useful for reuse across a class of domain-specific applications or product lines. By varying the composition of components suited to a particular product line, an assortment of applications can be developed to support differing operational needs. A top-down approach to the design components for a specific(More)
With an increase in full-body scans and longitudinal acquisitions to track disease progression, it becomes significant to find correspondence between multiple images. One example would be the monitoring size/location of tumors using PET images during chemotherapy to determine treatment progression. While there is a need to go beyond a single parametric(More)
