Neurosurgery targeting and delivery system for brain structures
InactiveUS20050171558A1Avoid excessive errorAccurate placementDiagnosticsSurgical navigation systemsData setMedicine
Morphing or fitting a brain atlas to a diagnostic image data set of the patient, or to a patient registered to the brain atlas, is enhanced using measurements of one or more physical characteristics of the brain taken with the aid of an instrument as it is being inserted into the brain. The measurements are then compared against known physical characteristics of certain brain structures, thus permitting correlation of the measured physical characteristic to a brain structure. The brain atlas then may be morphed or deformed so that the identified brain structure in the atlas is at or near the position at which the measurement was taken, as known from the tracked position of the instrument.

Image guided robotic system for keyhole neurosurgery
ActiveUS20090177081A1Scan accuratelyPotentially accurateSurgical needlesSurgical navigation systemsEntry point3d surfaces
A novel image-guided system for precise automatic targeting in minimally invasive keyhole neurosurgery. The system consists of a miniature robot fitted with a mechanical guide for needle, probe, or catheter insertion. Intraoperative, the robot is directly affixed to a head clamp or to the patient skull. It automatically positions itself with respect to predefined entry points and targets in a preoperative CT / MRI image following an anatomical registration with an intraoperative 3D surface scan of the patient facial features and a registration jig. The registration procedure is a novel three-way scheme, in which the intraoperative surface scan including the registration jig is matched to a model generated from the preoperative CT / MRI image, the robot position is known in relation to the registration jig, and the entry and target points are known from the preoperative CT / MRI image, such that the robot position can be related to the entry and target points.
