Phantom and in vivo validation of a novel contactless registration method for robot-assisted SEEG surgery.

ABSTRACT:

Background

In recent years, robot-assisted stereotactic system has been widely used in stereo-electroencephalogram (SEEG) surgery. However, current registration mainly based on bone-fiducial registration (CBR) is limited by the inconvenient of repeated contact during the process. Here, a novel contactless optical-tracking registration (OTR) were applied for SEEG using robot-assisted stereotactic system. To demonstrate the accuracy and convenience of the novel OTR method compared with contact CBR method during the robot-assisted SEEG in phantom and animal model study.

Methods

A head phantom and 12 Bama pigs (Sus scrofa domestica) with six under CBR and six under OTR were selected for the SEEG. Procedures were performed using the robot-assisted stereotactic system in different
