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: Systems and methods for collecting and processing physical space data for use while performing an image-guided surgical (IGS) procedure are provided. The system and method includes obtaining a computer model of a non-rigid structure of interest in a patient and performing a rigid alignment of the computer model and surface data in a patient space associated with at least a portion of the non-rigid structure. The system and method also include computing a deformation of the computer model that provides a non-rigid alignment of the computer model and surface data, the deformation computed using a set of boundary conditions defined for each node of the computer model based on the rigid alignment and a kernel function. Additionally, the system and method can include displaying data for facilitating the IGS procedure based on the deformation.

Abstract: A method of compensation for intra-operative brain shift of a living subject. In one embodiment, the method includes the steps of pro-operatively acquiring brain images of the living subject, constructing a statistical atlas of brain displacements of the living subject from the pro-operatively acquired brain images, intra-operatively measuring brain displacements of the living subject, deriving an intra-operative displacement atlas from the intra-operatively measured brain displacements and the statistical atlas, obtaining intra-operative brain shift at least from the intra-operative displacement atlas, and compensating for the intra-operative brain shift.
