Abstract
Magnetic Resonance Imaging (MRI) serves as a critical tool in modern medical diagnosis, and its accuracy is directly linked to patient treatment and recovery. However, unintentional patient movement during MRI scans often results in motion artifacts on the images, significantly compromising the precision of diagnosis. Traditional solutions typically involve identifying and addressing these issues after the scanning sequence is completed, leading to significant resource waste and delays in patient treatment. Here, we propose a flexible tactile sensor array system based on triboelectric nanogenerators (TENGs) for real-time monitoring of head motion artifacts in MRI. The unique design of the tactile sensor structure, operating in a dual-electrode mode, maintains high sensitivity and a wide response range, even with a minimal surface area. The advantage of TENG is the wide range of material choices, ensuring that a proper selection will not interfere with MRI during application. By integrating TENG sensor technology and control program systems, this solution provides a novel approach for monitoring head motion artifacts in MRI. On the basis of ensuring patient comfort, it has saved the time and money costs of monitoring, improved the efficiency of detection, and demonstrated significant potential in the field of medical imaging.
磁共振成像(MRI)是现代医学诊断的重要工具,其准确性直接关系到病人的治疗和康复。然而,在磁共振成像扫描过程中,患者的无意移动往往会导致图像上出现运动伪影,严重影响诊断的准确性。传统的解决方案通常需要在扫描序列完成后才能识别和解决这些问题,从而导致严重的资源浪费和患者治疗延误。在此,我们提出了一种基于三电纳米发电机(TENGs)的灵活触觉传感器阵列系统,用于实时监测磁共振成像中的头部运动伪影。触觉传感器结构设计独特,以双电极模式工作,即使表面积极小,也能保持高灵敏度和宽响应范围。TENG 的优势在于材料选择范围广,可确保在应用过程中选择适当的材料不会干扰磁共振成像。通过整合 TENG 传感器技术和控制程序系统,该解决方案提供了一种监测磁共振成像中头部运动伪影的新方法。在确保病人舒适度的基础上,它节省了监测的时间和金钱成本,提高了检测效率,在医学成像领域展现出巨大潜力。
