Dr. Peters' laboratory is concerned with the development and validation of tools that allow surgeons to make efficient use of images, produced by sophisticated 3-D imaging systems, during surgical procedures. The objective of minimally-invasive neurosurgery is to resect or lesion the smallest volume of brain tissue, causing the least trauma to the patient while achieving the desired therapeutic result.

Currently localization of epileptic regions in the brain is quite crude, and is often only as specific as to which side of the brain the seizure focus is located. For this reason, often most of the temporal lobe of the brain is removed, even though the affected region may reside within a few cubic millimetres of tissue located within the lobe. Excessive tissue removal can affect speech, cognitive and memory function of patients. Accurate minimally-invasive removal of the focus after identifying this region via MRI will spare these functions after surgery.
