“…To compare the targeting accuracy, the Euclidean error d and its standard deviation SD d are adopted in this study. In some articles, only vector errors were reported [17,19,37,38,39,40]. In this situation, d was acquired with vector errors using equation 1 [18,29,31].…”

“…To help improve targeting accuracy, new techniques such as rapid prototyping, image fusion and advanced robotics are developed. In the early days, only frame-based stereotactic systems were used for electrode implantation [17,18,19,20]. Nowadays, various newly developed systems integrated with novel techniques such as optical navigation and interventional magnetic resonance imaging (iMRI) have entered the clinical theater, making the electrode implantation operation increasingly diverse [15,21,22,23], but the information on the targeting accuracy of different stereotactic systems is fragmented and mainly appears in various clinical reports [24,25,26,27].…”

Background: Accurate implantation of a depth electrode into the brain is of the greatest importance in deep brain stimulation (DBS), and various stereotactic systems have been developed for electrode implantation. However, an updated analysis of depth electrode implantation in the modern era of DBS is lacking. Objective: This study aims at providing an updated review on targeting accuracy of DBS electrode implantation by analyzing contemporary DBS electrode implantation operations from the perspective of precision engineering. Methods: Eligible articles with information on targeting accuracy of DBS electrode implantation were searched in the PubMed database. Results: An average targeting error of DBS electrode implantation is reported to decrease toward 1 mm; the standard deviation of targeting error is decreasing toward 0.5 mm. Targeting accuracy is not only found to be affected by individual surgical steps, but also systematically affected by the architecture of the implantation operation. Conclusion: A systematic strategy should be adopted to further improve the targeting accuracy of depth electrode implantation. Attention should be paid to optimizing the whole electrode implantation operation, which can help minimize error accumulation or amplification throughout the serially connected procedures for DBS electrode implantation.

“…CT does not suffer from the inherent inaccuracy produced by magnetic field distortion, and co-registration of the data improves the spatial resolution of the MR data to be stereotactically accurate within the millimetre range. 35 The trajectory to the target is planned to avoid traversing sulci, vessels, eloquent brain and the ventricles.…”

Central nervous system (CNS) stimulation is becoming increasingly prevalent. Deep brain stimulation (DBS) has been proven to be an invaluable treatment for movement disorders and is also useful in many other neurological conditions refractory to medical treatment, such as chronic pain and epilepsy. Neuroimaging plays an important role in operative planning, target localization and post-operative follow-up. The use of imaging in determining the underlying mechanisms of DBS is increasing, and the dependence on imaging is likely to expand as deep brain targeting becomes more refined. This article will address the expanding role of radiology and highlight issues, including MRI safety concerns, that radiologists may encounter when confronted with a patient with CNS stimulation equipment in situ.Central nervous system (CNS) stimulation is becoming increasingly prevalent.

Neuroimaging plays an important role in operative planning, target localization and post-operative follow-up. ANATOMY OF THE DEEP BRAIN NUCLEIThe basal ganglia are a complex group of anatomically and neurochemically interconnected structures whose role is the control of complex and intentional movements and to inhibit unwanted movements.1 They comprise the corpus striatum (caudate nucleus, nucleus accumbens and putamen), globus pallidus [external segment (GPe) and internal segment (GPi)], substantia nigra [compact part and reticular part (SNr)] and the subthalamic nucleus (STN) (Figure 1). The pedunculopontine nucleus is highly interconnected with the basal ganglia and is now considered by many to be part of this group. Disorders of the basal ganglia therefore manifest by movement, posture and muscle tone abnormalities.There are wider connections to other parts of the brain such as the thalamus, limbic cortex and prefrontal cortex. These highlight their role in cognition and emotion and explain their implication in some psychiatric disorders and the cognitive symptoms associated with movement disorders.It is these structures and their interconnected neighbours that are the targets for treatment by DBS. The STN is the most common target for DBS treatment because it is capable of treating the entire gamut of advanced Parkinson's disease symptoms, including tremor, rigidity, bradykinesia and drug-induced dyskinesia.2 DBS reduces the need for dopaminergic medication. The benefits are a reduction of motor signs and improvement of functionality in the off-medication phase, a reduction of the required medication dose and its associated complications, and an increased quality of life.3 The benefits usually persist for at least 2 years and can last for many more.The STN plays a key role in the basal ganglia-thalamocortical motor circuit (Figure 2). The striatum receives input from the cerebral cortex and direct pathway information pa...

“…To avoid distortion and to increase spatial information, many centers use MRI coregistered to CT for the preoperative planning. Occurring errors depend on the image fusion algorithm but seem to remain in acceptable limits [103,115], for example of around 1.3 mm for an image fusion based on mutual information [28]. On the contrary to such a rigid intrapatient fusion, it is well known that non-rigid atlas fusion to the patient's MRI introduces uncertainties [42,113] as the atlases do not take into account the discrete anatomical variations among individuals.…”

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.
