Title:
OPTICAL-ULTRASONIC DUAL-MODALITY IMAGING-BASED CAPSULE ENDOSCOPE
Document Type and Number:
WIPO Patent Application WO/2021/196771
Kind Code:
A1
Abstract:
The present invention is applicable to the technical field of capsule endoscopes, and provides an optical-ultrasonic dual-modality imaging-based capsule endoscope. According to embodiments of the present invention, mechanical guidance and delivery of a capsule endoscope main body by using a coaxial cable having an outer diameter smaller than that of the capsule endoscope main body enables the movement of the capsule endoscope main body inside a human body to be controllable, so that impact and friction of the coaxial cable against the human digestive tract can be effectively reduced, and in addition, by means of a shielding layer, electromagnetic radiation can be reduced and static electricity can be eliminated; optical image data of the human digestive tract is obtained by means of a camera module, ultrasonic scan data of the human digestive tract is obtained by means of an ultrasonic imaging module, and the optical image data and the ultrasound scan data are transmitted by means of the coaxial cable to an imaging system to perform real-time image processing so as to obtain and display optical images and ultrasonic images, thereby achieving optical imaging and ultrasonic imaging, and presenting multidimensional tissue imaging screens of the human digestive tract in real time, and obtaining information of pathological changes of deep tissues.
