Embodiment Construction

[0029] The specific embodiments provided by the present invention will be described in detail below in conjunction with the accompanying drawings.

[0030] Please refer to figure 1 , figure 1 It is a flow chart of a dynamic video production method for fundus fluorescein angiography of the present invention. A dynamic video production method for fundus fluorescein angiography, the dynamic video production method for fundus fluorescein angiography includes shooting static photos in the early stage and making dynamic videos in the post-stage; where the static photos are taken in the early stage, which solves the problem that the huge amount of data cannot be achieved after the whole continuous video shooting Dealing with disadvantages.

[0031] The static photos taken in the early stage are taken with time-lapse intervals. The details of the static photos taken in the early stage are as follows: 1) Before the radiography, first take 1-2 photos without red light, and then take 2...

Abstract

The invention relates to a fundus fluorescein angiography dynamic video production method. The fundus fluorescein angiography dynamic video production method comprises an earlier-stage static photo taking step and a later-stage dynamic video production step. The method has the advantages that the tradition of presenting angiography by a static picture in conventional fundus fluorescein angiography is overturned; the defect that a large quantity of data cannot be processed after whole-process continuous video shooting is overcome at an earlier stage by an interval delay shooting method; taken photos are synthesized into a complete video for representing a whole fundus fluorescein angiography process through video software at a later stage; the whole fundus fluorescein angiography process can be presented by the video; an oculist can diagnose and treat fundus oculi diseases more easily, and find certain pre-existing tiny lesions which cannot be found through static photos; and patients can know own eye diseases. The method has a wide application prospect in clinical popularization, and can be applied to all medical imaging fields. A new era of medical imaging is created.

Description

technical field [0001] The invention relates to the technical field of fundus examination in ophthalmology, in particular to a dynamic video production method for fundus fluorescein angiography. Background technique [0002] Fundus fluorescein angiography, that is, the use of energy to emit fluorescent substances, such as sodium fluorescein, is quickly injected into the subject's venous blood circulation to the fundus blood vessels, and after being irradiated by a connected blue excitation light source, the fluorescein sodium that circulates into the eye Yellow-green fluorescence is excited, and at the same time, a fundus camera equipped with a special filter combination is used to take pictures in time and observe the dynamic process of fundus circulation. [0003] Fundus fluorescein angiography has the advantages of being able to observe many tiny lesions that could only be found during autopsy; and through the process of fluorescein circulating in fundus vessels with bloo...
