We present a novel robotic neuronavigation system (RONNA G4), used for precise preoperative planning and frameless neuronavigation, developed by a research group from the University of Zagreb and neurosurgeons from the University Hospital Dubrava, Zagreb, Croatia. The aim of study is to provide comprehensive error measurement analysis of the system used for the brain biopsy.
Frameless stereotactic robot-assisted biopsies were performed on 32 consecutive patients. Post-operative CT and MRI scans were assessed to precisely measure and calculate target point error (TPE) and entry point error (EPE).
The application accuracy of the RONNA system for TPE was 1.95 ± 1.11 mm, while for EPE was 1.42 ± 0.74 mm. The total diagnostic yield was 96.87%. Linear regression showed statistical significance between the TPE and EPE, and the angle of the trajectory on the bone.
The RONNA G4 robotic system is a precise and highly accurate autonomous neurosurgical assistant for performing frameless brain biopsies.
我们展示了一种新型的机器人神经导航系统（RONNA G4），由萨格勒布大学的一个研究小组和萨格勒布杜布拉瓦大学医院的神经外科医生开发，用于精确的术前规划和无框架神经导航。该研究的目的是提供用于脑活检的系统的全面误差测量分析。
对 32 名连续患者进行了无框架立体定向机器人辅助活检。对术后 CT 和 MRI 扫描进行评估，以精确测量和计算靶点误差（TPE）和入点误差（EPE）。
RONNA 系统的应用精度为 TPE 为 1.95±1.11mm，EPE 为 1.42±0.74mm。总的诊断率为 96.87%。线性回归显示 TPE 和 EPE 之间以及轨迹在骨头上的角度之间存在统计学意义。
RONNA G4 机器人系统是一种精确和高度精确的自主神经外科助手，用于进行无框架脑活检。
