Development of a criterion for repositioning a relocatable stereotactic frame using depth helmet measurements.
Based on 95% confidence intervals in the normal distribution, a criterion was developed for a relocatable stereotactic frame depth helmet measurement. The method for obtaining such a criterion is described. The criterion states that, if more than two points deviate more than 1.5 mm the frame should be repositioned.
