Neurosurgery targeting and delivery system for brain structures
First Claim
1. A method for morphing or fitting a brain atlas to a diagnostic image data set of the patient, or to a patient registered to the brain atlas, the method comprising receiving measurements indicative one or more physical characteristics of the brain taken with the aid of an instrument as it is being inserted into the brain;
- tracking the position of the instrument;
comparing the measurements against known physical characteristics of certain brain structures, thereby correlating of the measured physical characteristic to a brain structure; and
morphing or deforming the brain at last ed or deformed so that the identified brain structure in the atlas is at or near the position at which the measurement was taken.

Abstract
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.

4. A surgical navigation system, comprising:
-
a localizer for tracking the position of an instrument; and
a computer in communication with the localizer for receiving information from which to determine the position of an instrument;
wherein the computer stores a computer program that, when executed causes the computer to undertake the following process;
receiving measurements indicative one or more physical characteristics of the brain taken with the aid of an instrument as it is being inserted into the brain;
tracking the position of the instrument;
comparing the measurements against known physical characteristics of certain brain structures, thereby correlating of the measured physical characteristic to a brain structure; and
morphing or deforming the brain at last ed or deformed so that the identified brain structure in the atlas is at or near the position at which the measurement was taken.
