Abstract

A method for obtaining vocal cord medical detection image information comprises the steps that firstly, mechanical signals generated when vocal cords vibrate are obtained and converted into vocal cord vibration electric signals, and the vocal cord vibration electric signals are square wave signals; and 2, selecting a rising edge of the vocal cord vibration electric signal as a trigger signal according to a set mode to obtain a vocal cord medical detection image. The invention also provides a system for acquiring vocal cord medical detection image information, comprising: a vibration sensor, the vocal cord vibration electric signal generated by the vibration sensor being a square wave signal; an image sensor is arranged in the laryngoscope lens; and the endoscope host is provided with a processor. The device has the characteristic of self-adaption to the vocal cord vibration frequency, a video image when the vocal cord is located at a certain fixed position can be observed, stable image display is achieved, and medical staff can conveniently check vocal cord diseases.

Description

technical field [0001] The present invention relates to the technical field of medical imaging, and more specifically, to a method for obtaining medical detection image information of vocal cords and a system for obtaining medical detection image information of vocal cords. Background technique [0002] Laryngoscopy is a medical detection method that can directly observe diseases of the nose and throat. [0003] When performing laryngeal examination on humans, due to the high vibration frequency of human vocal cords, usually between 65Hz and 1KHz, during routine laryngoscopy, due to the vibration of the vocal cords (the vocal cords are always vibrating during the examination) and image acquisition The frequency (the number of frames of image acquisition) does not have a fixed phase relationship, so the acquired images are always changing, and the images of the vocal cords during vibration cannot be clearly seen, which is not conducive to the discovery and diagnosis of lesion...
