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.

A method for augmented reality navigation of a medical intervention includes providing a stereoscopic head mounted display, the display including a pair of stereo viewing cameras, at least one tracking camera, and a stereoscopic guidance display. During a medical intervention on a patient, the patient's body pose is determined from a rigid body transformation between the tracking camera and frame markers on the scanning table, and the pose of an intervention instrument with respect to the table is determined. A visual representation of the patient overlaid with an image of the intervention target, the instrument, and a path for guiding the instrument to perform said medical intervention is displayed in the stereoscopic guidance display.

摘要:
A method and apparatus for presenting three-dimensional data to a physician is provided to facilitate the flexible navigation of an endoscope and surgical instruments with respect to anatomical structures. In accordance with a first embodiment a first set of data corresponding to a three dimensional model of a patient's anatomy is received. This three-dimensional model may be rendered from images taken in CT or MRI scanning, as discussed above In accordance with this embodiment, this model is then combined with a second set of data corresponding to a view obtained from an endoscope. In another embodiment, the view from the illustrative endoscope is displayed as an inset image on the display of the three-dimensional image. In yet another embodiment, the three-dimensional image comprises a graphical representation of at least a first surgical instrument, such as said endoscope. The surgeon may select among various combinations of views and may zoom in or out from any particular view.
