Endoscopic ultrasonic imaging device and method for nasopharynx cancer

Abstract

The invention relates to an endoscopic ultrasonic imaging device and an endoscopic ultrasonic imaging method for nasopharynx cancer. The device comprises a camera, a video signal processing unit, a control and imaging unit, an ultrasonic excitation and receiving unit and an ultrasonic transducer, wherein the camera is used for acquiring an optical tissue image on the inner surface of a nasopharynx; the video signal processing unit is used for converting an optical tissue image signal into a video digital signal; the control and imaging unit is used for storing and displaying the digital signal and sending a control instruction; the ultrasonic excitation and receiving unit is used for generating a specific pulse signal according to an ultrasonic control instruction for ultrasonic excitation, processing an ultrasonic echo signal and then performing ultrasonic image display; the ultrasonic transducer is used for generating an ultrasonic wave for scanning the interior of the nasopharynx according to the pulse signal, receiving the ultrasonic echo signal and converting the ultrasonic echo signal into an electric echo signal; the ultrasonic excitation and receiving unit is also used for processing the electric echo signal; the control and imaging unit is also used for performing ultrasonic imaging according to the processed electric echo signal. The detection accuracy is improved.

Description

technical field [0001] The invention relates to medical equipment, in particular to an endoscopic nasopharyngeal carcinoma ultrasonic imaging device and method. Background technique [0002] Nasopharyngeal carcinoma is a malignant tumor that originates in the nasopharynx. About 600,000 new patients with nasopharyngeal carcinoma are diagnosed every year in the world, ranking fifth in the incidence of malignant tumors. The early symptoms of nasopharyngeal carcinoma are not obvious, and the middle and advanced symptoms include bloody nose, bloody sputum, tinnitus, deafness, cervical lymphadenopathy, headache, facial numbness, diplopia, drooping eyelids, blindness, dysphagia, hoarseness, tongue deviation Wait. Most of the symptoms do not cause pain to the patient, and are easily confused with symptoms of other etiologies; usually, nasopharyngeal carcinoma occurs in the mucous membrane of the inner wall of the nasopharynx, which is relatively hidden, and it is difficult to accu...
