    摘要: A system and method for instrument placement using an image based navigation system is disclosed. A target of interest is identified in a medical image of a patient. An image plane is displayed that goes through a center of the target. The image plane has a configurable orientation. The image plane is used to select a path for an instrument from a position on the patient's skin to the center of the target. A trajectory plane is viewed from a tip of the instrument to the center of the target. The trajectory plane reflects an orientation of the instrument. A particular trajectory plane is selected that is representative of a desired orientation of the instrument. An image of the particular trajectory plane is frozen. The instrument can then be inserted using a virtual guide and is navigated toward the target.

    摘要: A system and method for automatically registering a three dimensional (3D) pre-operative image of an anatomical structure with intra-operative electrophysiological (EP) points of a 3D electro-anatomical (EA) image map of the anatomical structure is disclosed. The pre-operative image is displayed in a first supporting view. The intra-operative EA image map is displayed in a second supporting view. An alignment of the pre-operative image with the intra-operative map is performed by identifying at least one corresponding point on each image. The view of the pre-operative image is integrated with the EA map based on the alignment.

    摘要: An endo-robot can be tracked and a reconstructed 3D volume of data can be created for virtual endoscopy. The 3D position and orientation of each image captured by the endo-robot is determined. The longitudinal distance traveled inside the structure of interest is determined. The position, orientation and longitudinal distance are used to register the position of the endo-robot to a corresponding position inside the 3D volume of data. Virtual endoscopy can be used to locate areas of interest and correlate clinical findings with the images of the areas of interest.
