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 registering pre-operative magnetic resonance (MR) images with intra-operative MR images is disclosed. A pre-operative MR image of an object is received. A set of intra-operative MR images of the object is received. The pre-operative MR image is rigidly registered with the initial intra-operative MR image. The subsequent set of intra-operative images is deformably registered. The pre-operative MR image undergoes both rigid and deformation transformation to match specification of each image with in intra-operative MR image set.

摘要： 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.
