|20120215096||SYSTEMS & METHODS FOR PLANNING AND PERFORMING PERCUTANEOUS NEEDLE PROCEDURES - A system and method for planning volumetric treatment by percutaneous needle procedures obtains a volumetric image data set of a subject including an identifiable region requiring treatment. An effective treatment volume is defined relative to the needle position for at least one needle carrying a treatment applicator. One or more proposed inserted needle position is defined such that a effective treatment volume corresponding to the one or more proposed inserted needle position provides coverage of the region requiring treatment. The effective treatment volume for one or more needles can then be visualized in the context of slices of 3D image data. One or more entry point and corresponding virtual target are then defined relative to a frame of reference of the volumetric image data set for use in navigation of the at least one needle to the corresponding proposed inserted needle position.||08-23-2012|
|20100228534||METHOD, SYSTEM AND COMPUTER PRODUCT FOR PLANNING NEEDLE PROCEDURES - A system and method for planning a needle procedure include designating a target location within three-dimensional image data of a subject's body and defining a tentative route for insertion of a needle to the target location. The three-dimensional image data is processed to generate a graphic representation which indicates whether the tentative route intersects an obstacle of at least one type. In response to a user input, the graphic representation is then rotated about axes passing through the target location, thereby allowing selection of an updated route to the target which does not intersect an obstacle.||09-09-2010|
|20090290174||METHOD FOR PRODUCING PRINTED PATCHES FOR OPTICAL AND HIGH-CONTRAST GUIDANCE - A method is described for producing printed patches to provide a plurality of color markings and high-contrast markings as aligned arrangements of fiducial points. The printed color markings facilitate optical image processing and the printed high-contrast markings facilitate high-contrast image processing. These fiducial points enable a visible area of interest to be located by a person and associated with relevant high-contrast imaging data. This method includes providing a patch; printing at least one arrangement of color markings on the patch; and printing at least one arrangement of high-contrast markings on the patch. According to further features of certain embodiments the markings are aligned, can designate the same point, or can be disjointed.||11-26-2009|
|20080208041||System and Method For Optical Position Measurement And Guidance Of A Rigid Or Semi-Flexible Tool To A Target - A system for measuring the position of a hand-held tool relative to a body in six degrees of freedom employs a camera attached via a mechanical linkage to the tool so that the camera moves together with the proximal portion of the tool and has a field of view including the distal end of the tool. A processing system processes images from the camera to determine a position of at least part of the tool. By employing optically identifiable fiducial reference points defined on the external surface of the body, a projection of the tool tip position onto a plane containing the target can be derived and displayed together with the target position, thereby facilitating guiding the tool to the target.||08-28-2008|
