A multispectral fundus imaging device and method based on an intelligent terminal

Abstract

The invention relates to the field of medical treatment and health, and discloses a multispectral fundus imaging device and method based on an intelligent terminal. The device comprises an illuminating module, a fundus image acquiring module and a data processing module; the illuminating module illuminates for a retina by a flash lamp LED via different light filters; and the fundus image acquiringmodule acquires images by using a camera of the intelligent terminal. Colorful images under specific wavelengths in a certain wavelength range are acquired, and after spectral rebuilding from an RGBvalue to a spectral value, acquisition of fundus multispectral images is finished. The acquired fundus multispectral images can be uploaded to an internet cloud via the data processing module, and after the fundus multispectral images are artificially and intelligent diagnosed in the cloud, the result is fed back to the intelligent terminal. Convenience of the multispectral fundus imaging system is improved; equipment costs are reduced; and medical informatization is promoted, the diagnosis precision is close to or exceeds the diagnosis precision of a doctor, self-inquiry of a patient is assisted favorably, the working efficiency is improved, and medical resources are reasonably configured.

Description

technical field [0001] The invention relates to the field of medical care and health, in particular to an intelligent terminal-based multispectral fundus imaging device and method. Background technique [0002] With the improvement of people's living standards and the arrival of the country's aging population, mobile health, family-style, and personal portable monitoring medical care are becoming more and more popular. The human retina is one of the observation targets with important clinical significance. By observing changes in the retina, the diagnosis of fundus diseases and even cardiovascular and cerebrovascular diseases can be realized. [0003] Because different light passes through the fundus in different depths and is absorbed by different substances, it is possible to obtain images of different layers of the fundus and richer biomedical information by selecting light of appropriate wavelengths. However, most of the existing multi-spectral fundus imaging systems u...

AI Technical Summary

Problems solved by technology

[0005] (1) Existing multi-spectral fundus imaging systems are bulky and cumbersome, and poor in portability

[0006] (2) The existing multi-spectral fundus imaging system has high equipment cost

Its expensive equipment costs lead to high diagnostic costs for patients, and is not conducive to the promotion of this equipment in small and medium hospitals

[0007] (3) The existing multi-spectral fundus imaging system equipment has low openness, which is not conducive to artificial intelligence diagnosis based on the Internet and big data
