Abstract: A system and method for using pre-procedural images for registration for image-guided therapy (IGT), also referred to as image-guided intervention (IGI), in percutaneous surgical application. Pseudo-features and patient abdomen and organ surfaces are used for registration and to establish the relationship needed for guidance. Three-dimensional visualizations of the vasculature, tumor(s), and organs may be generated for enhanced guidance information. The invention facilitates extensive pre-procedural planning, thereby significantly reducing procedural times. It also minimizes the patient exposure to radiation.

Abstract: A system and method to conduct image segmentation by imaging target morphological shapes evolving from one 2-dimension (2-D) image slice to one or more nearby neighboring 2-D images taken from a 3-dimension (3-D) image. One area defined by a user as a target on an image slice can be found in a corresponding area on a nearby neighboring image slice by using a deformation field generated with deformable image registration procedure between these two image slices. It allows the user to distinguish target and background areas with the same or similar image intensities.

Abstract: An apparatus and related methods using a variety of heterogeneous sensors to accurately track, in real time, the location of the tip of a surgical instrument inside the human body. The system accounts for real time changes in the surrounding environment during surgery, and when integrated with noninvasive image-guided surgery (IGS), this invention makes IGS possible and safe without tedious offline calibration. Sensors include, but are not limited to, optical, electromagnetic (EM), and sonar.
