Coronary artery load detecting system and method

Abstract

The invention provides a coronary artery load detecting system and a coronary artery load detecting method. The coronary artery load detecting method comprises the following steps: S1, acquiring the cross sectional area of a reference cavity, and acquiring voltage values of a main device at a position corresponding to the cross sectional area of the reference cavity under the lower frequency state and the high frequency state respectively; S2, acquiring the voltage values of the main device at positions of the bottom end or top end of a to-be-tested object under the lower frequency state and the high frequency state respectively under the same current; S3, driving the main device to move at uniform speed, and acquiring the voltage value of the main device in the movement process under the same current and under the lower frequency state; and S4, acquiring the cross sectional areas of all the positions of the to-be-tested object according to the preset fixed current value, the cross sectional area of the cavity, and the acquired voltage values. According to the system and the method, the voltage values of all the positions of the to-be-tested object are acquired through the frequency conversion manner, and further, the cross sectional areas of all the positions of the to-be-tested object are analyzed; and the parameters including the plaque parameters and the FFR of all the positions of the to-be-tested object are acquired according to the cross sectional areas, the operation and processing processes are greatly simplified, and the detection cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of medical detection, and relates to a coronary artery load detection system and a detection method. Background technique [0002] With the rapid development of biomedical engineering, how to improve the early prevention and treatment of human diseases, enhance the function of the body, and improve the level of health has always been a common concern of people; correspondingly, people have higher and higher requirements for medical detection methods. The method has been developed from manual detection combined with automated equipment for detection. In the prior art, a single form of imaging diagnostic equipment is used for detection. However, it cannot meet the needs of early diagnosis of diseases; a new detection system that combines form and function is the development of medicine. Needs, the development of functional examination and early diagnosis of diseases, and the development of rehabilitation and p...

[0002] With the rapid development of biomedical engineering, how to improve the early prevention and treatment of human diseases, enhance body functions, and improve health has always been a common concern of people; correspondingly, people have higher and higher requirements for medical detection methods. The method has been developed from manual detection combined with automated equipment for detection. In the existing technology, a single form of imaging diagnostic equipment is used for detection. However, it cannot meet the needs of early diagnosis of diseases; a new detection system that combines form and function is the development of medicine. Needs, the development of functional examination and early diagnosis of diseases, and the development of rehabilitation and prognosis evaluation of diseases are exactly the goals pursued by the development of modern medicine

[0003] At present, cardiovascular disease is the disease with the largest number of patients and the highest fatality rate. In the prior art, in the process of coronary artery load detection, CT, ultrasound and other methods are often used for detection, and the stenosis rate of blood vessels is directly obtained through this kind of equipment , so, the detection cost is high, and the accuracy of the detection results obtained is low; in addition, the above-mentioned equipment can only analyze the stenosis rate of blood vessels, and the diffuse plaque (the main cause of acute myocardial infarction) and FFR (reflecting the blood supply capacity of the heart) Insufficient information diagnosis
