“…Moreover, it is worth noting that operators are allowed to locate 10/20 landmarks in arbitrary sequence, since all of the 10/20 landmarks have already been identified in virtual space. For manual measurement, however, 10/20 landmarks must be measured in a sequence determined by the 10/20 rules (Jasper, 1958 ; Milnik, 2009 ). According to our experience, to manually measure Cz, i.e., the first landmark in the measurement sequence, the time cost is about 2 min.…”

“…According to Jasper, it takes four steps to complete the identification of all 21 landmark points in a one by one manner. Moreover, identification of 10–20 landmarks in later steps depends on the positions of 10/20 landmarks determined in prior steps (Jasper, 1958 ; Milnik, 2009 ). Such a tedious and error-prone procedure, involving both manual measurement and marking of 10/20 landmarks on the head of the subject, makes it difficult for the experimenter to maintain high reliability.…”

The International 10/20 system is an important head-surface-based positioning system for transcranial brain mapping techniques, e.g., fNIRS and TMS. As guidance for probe placement, the 10/20 system permits both proper ROI coverage and spatial consistency among multiple subjects and experiments in a MRI-free context. However, the traditional manual approach to the identification of 10/20 landmarks faces problems in reliability and time cost. In this study, we propose a semi-automatic method to address these problems. First, a novel head surface reconstruction algorithm reconstructs head geometry from a set of points uniformly and sparsely sampled on the subject's head. Second, virtual 10/20 landmarks are determined on the reconstructed head surface in computational space. Finally, a visually-guided real-time navigation system guides the experimenter to each of the identified 10/20 landmarks on the physical head of the subject. Compared with the traditional manual approach, our proposed method provides a significant improvement both in reliability and time cost and thus could contribute to improving both the effectiveness and efficiency of 10/20-guided MRI-free probe placement.

“…Gegebenenfalls werden die Elektroden an T1 und T2 ergänzt, bei einer Haube zumeist mit Klebeelektroden. Die Positionen werden wie folgt gefunden: Linie zwischen dem äußeren Gehörgang und dem lateralen Augenwinkel, vom Ohr 1/3 der Strecke in der Richtung auf das Auge und 1 cm aufwärts [8].…”

“…Moreover, this extensively used technique also faces some issues in terms of reliability and initial time cost, largely due to the manual landmark evaluation procedure on the surface of head [196]. So that, kind of a laborious and error-susceptible procedure (making manual landmark measurements on the subject's head), makes it very difficult for the researcher to maintain a high accuracy.…”

Methodologies on the Enhanced Spatial Resolution of Non-Invasive Optical Brain Imaging: A Review

et al. 2019

View full text Add to dashboard Cite

Optical brain imaging (OBI) has the potential for a bright future thanks to its low cost and portability relative to other biomedical imaging modalities. Temporal and spatial resolutions are considered to be the discriminatory features for selection of biomedical imaging equipment. OBI systems, however, still face the bottleneck of limited spatial resolution. In this study, existing methodologies and designs for enhancement of spatial resolution of OBI are comprehensively summarized. This is the first study reviewing all such techniques, therefore, is beneficial for researchers working in this field. The study presents general overview of principle of OBI followed by pros and cons specifically the challenges in enhancement of spatial resolution. Later, different novel existing methodologies, algorithms design and configurations, phantom related studies presenting spatial resolution enhancement have been discussed. Finally, conclusion and future directions are presented with an idea to enhance the spatial resolution of OBI up to nanoscale.
