Medical swallowing image collection device and image processing method thereof

Abstract

The invention discloses a medical swallowing image collection device and an image processing method thereof. The device comprises a digital collection card, a computer and a display. The digital collection card is inserted into a slot of a peripheral component interconnect-express (PCI-E) of the computer, is connected with a digital gastrointestinal device through a data line and sends collected image data of the digital gastrointestinal device to the computer in real time. The computer further comprises a memory for storing the image data and a processing module for processing images. The method comprises the steps of reading images in the swallowing process; extracting key frame images in the swallowing process; and identifying conditions of every part according to difference of every key part on the key frame images in the swallowing process. The medical swallowing image collection device is high in collecting precision; by image data processing, detailed quantitative analysis can be performed on the dynamic swallowing process, and every key parameter is measured and calculated; and image data can be called at any time so as to be used for reassessment and therapeutic effect comparison.

Description

technical field [0001] The invention relates to the field of medical detection research, in particular to a medical swallowing image acquisition device and an image processing method thereof. Background technique [0002] Swallowing refers to the action or the whole process that the bolus formed by chewing food is transported from the mouth to the stomach. This movement lasts very short and can usually be completed within 1 second. Routine clinical physical examination is difficult to comprehensively evaluate swallowing function, and it is easy to miss the diagnosis of severe swallowing disorders such as aspiration (food bolus enters the vestibule of the larynx and reaches below the glottis), especially for latent aspiration that does not cause obvious symptoms such as coughing Physical examination is difficult to find. Analyzing the physiology of swallowing movements during the oropharyngeal phase has long been considered extremely challenging. [0003] The Video Fluorosc...

Problems solved by technology

Some need to use multiple image analysis software at the same time for auxiliary analysis, the process is cumbersome and complicated, and it takes a lot of time and energy

[0005] At the same time, at present, swallowing imaging is mostly performed by digital gastrointestinal imaging equipment, which can only save a few images at present, and the acquisition accuracy is only 10-15 frames per second, and the image is seriously distorted and inaccurate. The time is short, and it cannot be collected for a long time, which will affect further image analysis later
