Purpose
We present a new system for 3D ultrasound-guided placement of cerebral ventricle catheters. The system has been developed with the aim to provide accurate ultrasound-based guidance with only minimal changes to the current surgical technique and workflow.
Methods
The system consists of a pre-calibrated navigation adapter for the catheter and a reference frame attached to a standard surgical retractor in addition to an ultrasound-based navigation system with a probe that fits on top of a standard burr hole.
Results
The accuracy of the pre-calibrated system has been evaluated, and our measurements indicate that the accuracy of the pre-calibrated system is better than 3 mm. We also present a clinical case.
Conclusions
The navigation accuracy is considered sufficient for clinical use, and initial clinical tests are promising. Further testing will be necessary to fully evaluate the performance of the system in a clinical setting.
