Abstract

An endoscopic ultrasonic imaging device and method for nasopharynx cancer. The device comprises: a camera (110), used for acquiring an optical tissue image on the inner surface of a nasopharynx; a video signal processing unit (120), used for converting an optical tissue image signal into a video digital signal; a control and imaging unit (130), used for storing and displaying the digital signal and sending a control instruction; an ultrasonic excitation and receiving unit (140), 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; and an ultrasonic transducer (150), 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 (140) is also used for processing the electric echo signal; the control and imaging unit (130) 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. 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 accurately iden...
