Magnetic resonance imaging (MRI) is better than other imaging equipment in detecting tumors, and navigation for robotic breast intervention biopsy. However, material requirements for robots driving devices are demanding incredibly because of the environment. Given this problem, a novel double cable-conduit driving method is put forward in this paper, which can be used in MRI for breast intervention robots. Besides, lebus grooves are adopted to the driving wheels, which enable the system to realize remote-range and large-scale driving on the premise that the precision can be further enhanced. The driving characteristic of the novel cable-conduit is established. Moreover, the cable-conduit experimental data proves the results of theoretical deduction. Finally, the cable-conduit driving device is compensated, the average errors in the [Formula: see text], [Formula: see text], and [Formula: see text] directions of the needle tip entering the tissue are less than 2[Formula: see text]mm. The consequence verifies that it can meet the requirements for breast biopsy robot application under MR environment.

Abstract BACKGROUND: Neurosurgery aims to achieve maximal tumor resection while preserving neurological function. Tools such as neuronavigation, high-field intraoperative magnetic resonance imaging (iMRI), and intraoperative neurophysiological monitoring (IOM) have consistently helped to achieve this goal, but integration has often been difficult. Surgery of eloquent areas requires IOM, which in an operating theater equipped with high-field (1.5-T) iMRI could present several issues. OBJECTIVE: To identify the electrodes types more suitable for IOM in a high-field iMRI operating theater by performing an experimental study on phantoms, to report our experience with platinum-iridium (Pt/Ir) electrodes during surgery, and to prove that integration between IOM with Pt/Ir electrodes and high-field iMRI is safe and reliable. METHODS: Electrodes of different materials (gold, Pt/Ir, and stainless steel) were tested on jelly phantom and apples to evaluate their safety and compatibility. Subsequently, electrodes were tested on 5 healthy volunteers before being used on patients. RESULTS: None of the different electrodes presented thermal instability, and no damage to the volunteers’ skin occurred. Stainless steel electrodes caused severe imaging distortion. Gold electrodes had no distortion, but their high cost makes their use in routine surgery unaffordable. Pt/Ir electrodes are significantly less expensive than gold electrodes and were completely safe, compatible, and suitable for use in an operating theater with high-field iMRI, providing excellent IOM and mild interference that did not affect the quality of intraoperative imaging. CONCLUSION: We suggest the use of Pt/Ir electrodes for IOM in 1.5-T iMRI suites.
