Abstract: The present invention provides a method, system and device for reflectional glare reduction in endoscope images. The reflective glare refers to clusters of congruent bright and often saturated image pixels caused by heterogenous surfaces of a tissue anatomy reflecting the illumination from a light source, which could be as annoying as distractive. Under automatic exposure control, in a scene of overexposure due to a reflection glare, the brightness of the glare is significantly higher than that of background image of tissue anatomy, and there is usually a gap between the two. Through mapping the pixel depth of the glare into the gap, the contrast between the glare and the background image is reduced, which improves the user experience of the endoscopy.

Abstract: 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.

Abstract: A system for endoscopic image registration, comprising a processing module, a camera module and a display module. The processing module builds a 3D spectral data module of a human body part based on preoperative 3D imageries, spectral characteristics of tissues of anatomy of the body part and of the light source; registers the module with image data captured by the camera module; generates masks on the model referencing a point cloud coupled with the image data, and displays one or more of the image data, the model before and after the registration in comparisons to assist endoscopy or guide robotic surgery.

Abstract: The invention discloses a bidirectional ultrasonic capsule for gastrointestinal measurement. The capsule comprises pairs of ultrasonic ranging probes to obtain correlated depth or morphology data of two sides of an inner wall of a digestive tract, wherein Probe 1 is configured to range a first distance to a first side of the inner wall of the digestive tract along a first direction and Probe 2 is configured to range a second distance to a second side of the inner wall of the digestive tract along an opposite direction to the first direction, and data of the first and second distances are correlated and a sum of the first distance, the second distance and a third distance between Probe 1 and Probe 2 is obtained as a directional cavity diameter of the digestive tract, which eliminates errors caused by motion of the capsule in the digestive tract in the unidirectional measurement of the prior art.

Abstract: 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.

Abstract: The invention discloses a gastrointestinal motility measurement system based on a digestive tract capsule, which comprises a data acquisition module, a data processing module and a capsule. The data acquisition module is configured in the capsule, and comprises an ultrasonic distance measuring device or a 3D camera for acquiring a depth map or a point cloud of the inner wall of the digestive tract; The data processing module is used for processing the depth map or the point cloud to obtain the surface data of the inner wall surface of the digestive tract; Further extraction of morphological features, including the inner wall of the digestive tract, curvature, inner diameter and volume, can be used as a reference for the evaluation of gastrointestinal motility.
