Article Snippet: Besides being validated to be a useful supplementary tool after optimal prior knowledge-based distortion correction, registration-based distortion correction, as used in Elements Cranial Distortion Correction (Brainlab AG, Munich, Germany), faces significant limitations: (1) the accuracy of the non-rigid registration declines as the deformation between image datasets increases, and (2) unlike methods that utilize prior knowledge, it does not consistently enhance the geometric accuracy of corrected images across all clinical scenarios.

Figure Lengend Snippet: Panel A —Schematic of the network connections with the direction of data flow between the various software components used in our technique. Preoperative and intraoperative radiological imaging was downloaded to the neuronavigation system from the hospital picture archiving and communication system (PACS). Segmentations and other preoperative surgical planning objects were retrieved from the remote planning server platform by the neuronavigation system. Tool-tip positions of optically tracked surgical instruments were streamed to the neuronavigation system. All three data types were, in turn, streamed through OpenIGTLink from the clinical neuronavigation platform to the research platform implemented in 3D Slicer. Panel B —Brainlab multiple-tip pointer with instrument adapter array. Panel C —Pre-calibrated Brainlab cranial pointer with a blunt tip. Panel D —Cavitron ultrasonic surgical aspirator (CUSA) with instrument adapter array. Panel E —Bipolar forceps with instrument adapter array. Panel F —Brainlab instrument calibration matrix. Panel G —Reflective marker spheres for optical neuronavigation. Panel H —Surgical team member performing the calibration process using the instrument calibration matrix for bipolar forceps mounted with a size ‘M’ instrument adapter array.
