开发了一种新颖的刚度传感系统，该系统通过将所提出的传感部件连接到内窥镜或摄像机上来工作。该系统提供了一种方法来研究只能用内窥镜观察的深层组织或物体的硬度，以检测异常情况。该系统是我们之前利用力可视化机制的力传感系统的扩展。力在传感部分可视化，并且可以通过内窥镜或相机作为视觉信息进行测量。传感部分还具有用作施加力的阈值的限制结构。通过测量极限处的力，可以测量刚度。通过捕获图像的亮度变化来检测限制点。所开发的传感部件具有无电子元件、一次性、简单、易于消毒、兼容MRI、成本低等优点。还提出了实现该机制的图像处理方法。该系统经过实验验证。
A novel stiffness-sensing system was developed that works by attaching the proposed sensing part to endoscopes or cameras. The system provides a method to investigate the stiffness of tissues or objects in deep areas that can only be observed with endoscopes in order to detect abnormalities. The system is an extension of our previous force sensing system that utilized a force visualization mechanism. The force is visualized at the sensing part, and can be measured as visual information via endoscopes or cameras. The sensing part also has a limiting structure used as a threshold for the applied force. By measuring the force at the limitation, the stiffness can be measured. The limitation point is detected by the brightness changes of the captured images. The developed sensing part has the advantages of having no electronic components, being disposable, simple, easy to sterilize, MRI-compatible, and low-cost. Image processing methods for realizing the mechanism are also proposed. The system was experimentally validated.
