Evaluation of Projection-Based Augmented Reality Technique in Cerebral Catheter Procedures

Abstract

Aim: In this experimental study, we evaluated the usability of a projection-based augmented reality technique, achieved by projecting cranial computerized tomography images from an external image source onto cattle skull, for localization of the frontal horn of the lateral ventricle and placing ventricular catheter. Materials and Methods: Eleven skulls obtained from fresh cattle cadavers were used for this experimental study. Axial computerized tomography images including the lateral ventricle sections were projected on the cattle skull over the superior surface. Puncturing needle was inserted from the surface into the frontal horn of the right lateral ventricle with the guidance of projection-based augmented reality images. Placements of catheters were evaluated by computerized tomography. Results: In two (18.18%) of the samples location of the catheter tip was found in unfavorable location. Acceptable results were achieved in six samples (54.54%). In the remaining three (27. 28%) of the samples, location of the needle tip was found in ideal location. Successful placement of ventricular catheters was achieved in nine (81. 82%) of the experimental materials using image projecting augmented reality technique. Discussion: The results of this study revealed that placement of cerebral catheters with the guidance of projection-based augmented reality is a safe, fast and simple procedure. This procedure provides the accurate location of the selected target seated within the brain parenchyma. This procedure may be used in similar kind of brain operations in the location of the lesion following more detailed and further investigations.
