    摘要： A system for use during a medical or surgical procedure on a body. The system generates a display representing the position of two or more body elements during the procedure based on a reference image data set generated by a scanner. The system produces a reference image of a body elements, discriminates the body elements in the images and creates an image data set representing the images of the body elements. The system produces a density image of the body element. The system modifies the image data set according to the density image of the body element during the procedure, generates a displaced image data set representing the position and geometry of the body element during the procedure, and compares the density image of the body element during the procedure to the reference image of the body element. The system also includes a display utilizing the displaced image data set generated by the processor to illustrate the position and geometry of the body element during the procedure. Methods relating to the system are also disclosed.

    摘要： A medical imaging system is provided that detects any change in relative position between the patient and the imaging device and corrects the image data for any motion that occurs. The medical imaging system includes: an imaging device for capturing two or more image data sets representative of a patient; a tracking subsystem for capturing patient position data that is indicative of the position of the patient and device position data that is indicative of the position of the imaging device; an image subtraction subsystem for performing a digital subtraction operation between at least two image data sets; and a motion correction subsystem configured to detect a change in the relative position between the patient and the imaging device and, upon detecting a change in the relative position, compensate in at least one of the first image data set and the second image data set for the change in relative position prior to performing the digital subtraction operation.

    摘要： A surgical instrument navigation system is provided that visually simulates a virtual volumetric scene of a body cavity of a patient from a point of view of a surgical instrument residing in the cavity of the patient. The surgical instrument navigation system includes: a surgical instrument; an imaging device which is operable to capture scan data representative of an internal region of interest within a given patient; a tracking subsystem that employs electro-magnetic sensing to capture in real-time position data indicative of the position of the surgical instrument; a data processor which is operable to render a volumetric, perspective image of the internal region of interest from a point of view of the surgical instrument; and a display which is operable to display the volumetric perspective image of the patient.

    摘要： A stereotactic navigation system for navigating an instrument to a target within a patient may include a stereotactic head frame, an imaging device, a tracking device, a controller and a display. The stereotactic head frame is coupled to the patient and is used to assist in guiding the instrument to the target. The imaging device captures image data of the patient and of the stereotactic head frame. The tracking device is used to track the position of the instrument relative to the stereotactic head frame. The controller receives the image data from the imaging device and identifies the stereotactic head frame in the image data and automatically registers the image data with navigable patient space upon identifying the stereotactic head frame, while the display displays the image data.
