摘要:

超声扫描机器人通过在扫描过程中保持超声探头与患者身体之间的紧密接触来实现患者内脏器官的自动成像。全面、高质量的超声扫描对于为患者提供准确的诊断和有效的治疗计划至关重要。超声扫描机器人通常工作在医生和机器人共存的环境中,因此在协作过程中需要兼顾效率和安全性。在本文中,我们提出了一种新的多模态控制方案的超声扫描机器人,其中三个互动模式被集成到一个单一的控制输入。具体地,扫描模式驱动机器人在期望的阻抗模型下跟踪患者身体上的时变轨迹;恢复模式允许机器人在超声探头与患者身体之间的物理接触丢失时主动重新接触身体;人类引导模式使机器人被动,使得医生可以安全地干预以手动重新定位探头。多种模式的集成使医生能够在任务期间随时安全地进行干预,同时也最大限度地提高了机器人的自主扫描能力。机器人的性能进行了验证的协同扫描任务的颈动脉检查。

英文摘要:

Ultrasound scanning robots enable the automatic imaging of a patient's internal organs by maintaining close contact between the ultrasound probe and the patient's body during a scanning procedure. Comprehensive, high-quality ultrasound scans are essential for providing the patient with an accurate diagnosis and effective treatment plan. An ultrasound scanning robot usually works in a doctor-robot co-existing environment, hence both efficiency and safety during the collaboration should be considered. In this paper, we propose a novel multi-modal control scheme for ultrasound scanning robots, in which three interaction modes are integrated into a single control input. Specifically, the scanning mode drives the robot to track a time-varying trajectory on the patient's body under the desired impedance model; the recovery mode allows the robot to actively recontact the body whenever physical contact between the ultrasound probe and the patient's body is lost; the human-guided mode renders the robot passive such that the doctor can safely intervene to manually reposition the probe. The integration of multiple modes allows the doctor to intervene safely at any time during the task and also maximizes the robot's autonomous scanning ability. The performance of the robot is validated on a collaborative scanning task of a carotid artery examination.
