HYBRID SPECTROSCOPY IMAGING SYSTEM FOR INTRAOPERATIVE EPILEPTIC CORTEX DETECTION
First Claim
1. A method for identifying epileptogenic cortices in a brain, surgical planning, and epileptogenic resection, the method comprising:
- detecting areas in the brain that are undergoing cerebral blood volume low frequency oscillations;
detecting areas in the brain that are undergoing blood oxygenation low frequency oscillations;
mapping clusters of the brain in which the cerebral blood volume low frequency oscillations are negatively correlated with the blood oxygenation low frequency oscillations; and
analyzing a time based relationship between the clusters of the brain that are undergoing negatively correlated low frequency oscillations to determine cause areas, which are areas of the brain that are causing negatively correlated low frequency oscillations to occur elsewhere.

Abstract
Methods and systems that detect and differentiate epileptogenic from eloquent and normal cortices are provided. A method for identifying epileptogenic cortices in a brain may include detecting areas in the brain that are undergoing cerebral blood volume low frequency oscillations, detecting areas in the brain that are undergoing blood oxygenation low frequency oscillations; mapping clusters of the brain in which the cerebral blood volume low frequency oscillations are negatively correlated with the blood oxygenation low frequency oscillations, and analyzing the time based relationship between the clusters of the brain that are undergoing negatively correlated low frequency oscillations to determine cause areas, which are areas of the brain that are causing negatively correlated low frequency oscillations to occur elsewhere.

14. A system for identifying epileptogenic cortices in a brain, the system comprising:
-
a means for identifying areas in the brain that are exhibiting cerebral blood volume low frequency oscillations; a means for identifying areas in the brain that are exhibiting blood oxygenation low frequency oscillations; a means for identifying clusters of the brain that are exhibiting a negative correlation (negatively correlated areas) between the cerebral blood volume low frequency oscillations and the blood oxygenation low frequency oscillations; and a means for identifying one or more cause areas, wherein the cause areas are negatively correlated areas that propagate or cause negatively correlated low frequency oscillations to occur in other areas of the brain. - View Dependent Claims (15, 16, 17, 18, 19, 20)
