ENDOSCOPIC ULTRASONIC IMAGING DEVICE AND METHOD FOR NASOPHARYNX CANCER

摘要

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.
