    摘要： Disclosed is a system and method for endoscopic image registration, based on a 3D spectral data model of a biological body part built on preoperative 3D imageries. Dynamic registration of the model is rendered in an endoscopy or a robotic surgery leveraging captured point clouds of surface of anatomy of the body part. Position of the body parts are tracked through the registration for navigating a surgical robot. The model masked with the point cloud is displayed so that change of the position of the body part could be easily perceived by the medical staff.

    摘要： The invention discloses a first gastrointestinal motility measurement system comprising a data acquisition module and a data processing module. The data acquisition module comprises an ultrasonic ranging device or a 3D camera for acquiring depth map or point cloud data. The data processing module processes the depth map or the point cloud to extract morphological features including curvature, inner diameter and volume of the digestive tract.
    The invention provides a second gastrointestinal motility measurement system, comprising a control module, a magnetic driving module, a magnetic positioning module and a capsule. The capsule is provided with a positioning magnet and a driving magnet. The positioning magnet generates a magnetic field signal, which is detected by the magnetic positioning module obtaining the position and motion data of the capsule in the digestive tract relative to an external coordinate system. The control module obtains a first position and motion data of the capsule under the action of gastrointestinal motility; obtains a second position and motion data of the capsule under the joint action of gastrointestinal motility and driving magnetic force; and estimates gastrointestinal motility according to the first and second position and motion data and the driving magnetic force.
