Experimental Evaluation of PARSISS Image Guided Surgery System

Abstract

Purpose: In this report, a thorough validation of PARSISS Image Guided Surgery has beenpresented.
Methods: Different experiments have been designed to evaluate Parsiss navigation system under three main scopes: first, a phantom study using a sophisticated precise phantom with 732 landmarks was constructed by 3d printing with layers of 16 micron thickness and 0.1 mm precision; second, performing preclinical cadaver experiment with titanium placed markers;
and third, clinical evaluation which was carried out on 957 cases from 2010 to 2014.
Results: Results obtained from three evaluation methods showed that the system was foundreliable and usable. Briefly, the average registration error in PARSISS precise phantom test was reported lower than 2 mm this which is clinically acceptable and reasonable in neurosurgery and ENT surgeries. In clinical evaluation, surgeons approved the accuracy and reliability of the system in thorough clinical evaluation in 94% of cases of 957 patients.
Conclusion: In this study, the results of all three approaches were positive and reliable. Especially, evaluations using a large number of patients showed that the PARSISS surgical navigation system has shown high level of reliability in clinical procedures.
