“…In some groups, supplementary techniques such as impedance measurements 6,7 or 30 microelectrode recording (MER) 8 are used to get additional information about the target area preoperatively identified on MR and CT images. Recently, optical measurements have been introduced as emerging technology which is a method for real-time presentation of grey-white tissue boundaries during stereotactic procedures.…”

“…This is one of the reasons in addition to the varying brain anatomy why intraoperative measurements are often performed. Such complementary intraoperative data acquisition methods can be for example impedance measurements while creating the trajectory for the DBS electrode, giving an idea of the surrounding structures passed [66,123]. Another often used method is microelectrode recording (MER) which is based on registering neuronal activity [26,40].…”

Deep brain stimulation (DBS) has become increasingly important for the treatment and relieve of neurological disorders such as Parkinson's disease, tremor, dystonia and psychiatric illness. As DBS implantations, and any other stereotactic and functional surgical procedure, require accurate, precise and safe targeting of the brain structure, the technical aids for preoperative planning, intervention and postoperative follow up have become increasingly important. The aim of this paper is to give an overview, from a biomedical engineering perspective, of a typical implantation procedure and current supporting techniques.Furthermore emerging technical aids not yet clinically established are presented. This includes the state-of-the-art of patient specific simulation of DBS electric field, optical methods for intracerebral guidance, movement pattern analysis, new stimulation devices and trends related to neuroimaging, visualization and navigation. As DBS surgery already today is an information technology intensive domain an "intuitive visualization" interface for improving management of these data in relation to surgery is suggested.

“…Microelectrode recording (MER) (26) is the most common intraoperative method used during DBS-implantation to record neuronal activity, but it can increase the bleeding incidents. (27) Intraoperative impedance measurement (28) is another well-known method but its resolution is low, especially compared with what can be achieved with optical techniques. (29) During stereotactic neurosurgery, impedance measurements are often performed in relation to RF lesioning, i.e., coagulation of a small brain region in the pallidum or thalamus to alleviate movement disorders.…”

Optical techniques are becoming increasingly important in healthcare, as both therapeutic and diagnostic tools. In neurosurgery, photonic technologies such as the microscope have already found widespread use. The overall aim of this paper is to give an overview of optical monitoring methods and their implementation and use in stereotactic and functional neurosurgery. The development steps presented in this paper range from radiofrequency-lesion size estimation using optics to a system adapted for neurosurgical intraoperative navigation during stereotactic deep brain stimulation (DBS) lead implantations. The two main optical methods implemented as intraoperative guidance tools are laser Doppler flowmetry and diffuse reflectance spectroscopy. By combining these fundamental methods with probe designs adapted to stereotactic systems, vessels can be tracked and "bar-codes" of tissue type along pre-defined trajectories used for DBS implantations identified. Examples of the optical methods used in relation to stereotactic DBS implantations are given.
