Method and system for obtaining value of bone mineral density of human body

Abstract

The invention is suitable for the technical field of medical image processing and applying, and provides a method and system for obtaining the value of the bone mineral density of the human body. The method includes the following steps: obtaining the high-low-energy image X ray injection strength, obtaining calibration parameters, collecting low-energy X ray images and high-energy X ray images of the bone area, preprocessing the collected images, receiving an interested area which is selected by a user and requires calculation of the value of the bone mineral density, locating an accurate area of the interested area which requires the calculation of the value of the bone mineral density, and calculating the value of the bone mineral density according to the Beer-Lambert law. By means of the method and system, dependence on hardware of a bone mineral density instrument can be reduced while the value of the bone mineral density is calculated; on the basis of a common digital X ray machine, the scheme of the method and system is applied, measurement and calculation of the bone mineral density of the human body can be achieved, the problem in the hardware is not required to be considered, and the production cost of the bone mineral density instrument is reduced to a certain degree. In addition, when the scheme is adopted for collecting the bone images, a standard body is not required, and the image collecting process is accordingly simplified.

Description

technical field [0001] The invention belongs to the technical field of medical image processing and application, and in particular relates to a method and system for obtaining human bone density values. Background technique [0002] Osteoporosis has become one of the six frequently-occurring diseases in the world. According to the report of the World Health Organization (WHO) in 1996, there are 380 million elderly people over the age of 65 in the world, and 65% of them suffer from osteoporosis. WHO has designated June 24th as "World Osteoporosis Day". According to reports, 90 million people in my country suffer from osteoporosis in varying degrees. Osteoporosis has become a common disease of middle-aged and elderly people. It is very necessary for middle-aged and elderly people to measure the mineral content in human bones, especially urban residents over 40 years old, especially middle-aged women , Calcium deficiency is more serious. Decreased mineral content in bones ca...

Problems solved by technology

[0018] The purpose of the present invention is to provide a method and system for obtaining human bone density values, aiming at solving the problem of using digital X-ray images in the prior art to measure bone density. (2) The bone density value obtained by using this scheme is not the real bone density value of the human body, but the density value of the corresponding position of the standard body that is equal to the pixel value of the X-ray image of the human skeleton
