Embodiment Construction

[0042] In order to make the object, technical solution and beneficial effects of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0043] see figure 1 , is the implementation process of the method for obtaining human body bone density value provided by the embodiment of the present invention, which includes the following steps:

[0044] In step S101, the X-ray incidence intensity of high and low energy images is obtained;

[0045] In the embodiment of the present invention, according to the Beer-Lambert law, when calculating the bone density value, it is necessary to know the measured value of the incident intensity of X-rays. For a specific digital X-ray machine, the imaging parameters of high and low energy imag...

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...
