Abstract
The invention discloses a method for measuring bone density by using digital X-ray images. The method mainly comprises the following steps of: acquiring and displaying images; preprocessing the images; and positioning and scanning a measured area, and converting and calculating the bone density. The method is established on the basis of the conventional bone density measurement by using X-rays; and according to the method, the bone density is measured through the digital X-ray images of skeleton parts, and thus the bone density is easy to measure, the cost is low and the accuracy is high.
Description
Technical field
The invention belongs to field of medical image processing, can be applicable to DR, CR, and the method for measuring bone density by the skeletal sites digital X-ray image that other technologies are obtained.
Background technology
Early stage measurement bone density technology arises from the perusal and the sxemiquantitative classification of X line analog image, thereby carries out diagnosing osteoporosis.Special-purpose monoenergetic or dual intensity X line borne densitometers utilize X ray and detector to obtain the digital X-ray image of different quality, by digital X line image is handled and measured, obtain the bone density parameter then.But these technology and hardware are closely related, check the cost height, are not easy unification, popularize, and it is low that bone density is obtained precision.Along with the development of X line image digitizing technique, the digital X-ray image is very universal, but is measuring also existence blank in the application of bone density technology.
Summary of the invention
The object of the present invention is to provide a kind of Applied Digital X line image to carry out the method for bone density measurement, it is to be based upon traditional X line that utilizes to carry out on the basis of bone density measurement, digital X-ray image by skeletal sites carries out bone density measurement, and bone density measurement is easy, cost is low, precision is high thereby reach.
In order to achieve the above object, the present invention is realized by following technical scheme.
A kind of Applied Digital X line image carries out the method for bone density measurement, mainly may further comprise the steps:
Image acquisition and demonstration: adopt the material that is close with the interior mineral of skeleton, make the standard body of known density, under same conditions of exposure, shine imaging with skeleton, obtain the skeleton X line digital picture of wanting measured zone and the standard body image of following, and show at computer screen;
Image pretreatment: to the X line digital picture of obtaining, carry out image is carried out pretreatment, so that can carry out unified interaction process to image at computer;
Interactive operation location survey zone: on X line digital picture, delineate the bone edge, limit measuring range;
Standard body calibration and bone density conversion: the equivalent density that the pixel value of skeletal sites is converted to standard body according to standard body.
Beneficial effect of the present invention is that the present invention is a comparatively general and complete bone density measurement that can be applied to all kinds of digital X-ray images, is used for diagnosing osteoporosis by bone density measurement.For the medical institutions that possessed the digital X-ray checkout facility at different levels, be one and realize easily, practical technique with low cost, bone density measurement precision height has very big meaning for universal bone density inspection item.
The specific embodiment
Below the specific embodiment of the present invention is done to describe in further detail.
A kind of Applied Digital X of the present invention line image carries out the method for bone density measurement, mainly may further comprise the steps: image acquisition and demonstration; The image pretreatment; The standard body calibration; Location scanning measured zone and bone density conversion Calculation; Set up the clinical diagnosis standard; Make the clinical scale diagnosis, write, export diagnosis report; Preserve the statistical correlation data result; Set up quality control, to guarantee the stability and the reliability of system.
Image acquisition of the present invention and step display: at first adopt the material that is close with the interior mineral of skeleton, make the standard body of known density, under same conditions of exposure, shine imaging with skeleton, utilize DR, CR, or other technologies obtain the skeleton X line digital picture of wanting measured zone and the standard body image of following, and utilize and transfer window setting technique to carry out computer screen to show.
Image pre-treatment step of the present invention: because the various technological disparities of obtaining the method for X line digital picture, the spatial resolution of image, size etc. have very big difference, be necessary to cut out, convergent-divergent, operations such as upset are carried out pretreatment to image, so that can carry out unified interaction process to image.
Interactive operation location survey of the present invention zone step: make the bone density of measurement meaningful, need adopt unified measuring point to all measuring objects, therefore measuring range needs the selected measured zone of unified standard.This process is to finish by the interaction process to image.According to image and dissection knowledge, the anatomic landmark with cursor specified measurement position skeleton adopts automanual method then, delineates the bone edge, limits measuring range by the operator.
Standard body calibration of the present invention and bone density switch process: the pixel value of X line digital picture, just certain dependency relation is arranged with bone density, can not be used for directly expressing bone density.Adopt the material that is close with the interior mineral of bone, adopt aluminum in the present embodiment, make the standard body of known density, under same conditions of exposure, shine imaging, the pixel value of skeletal sites is converted to standard body equivalence density according to standard body with skeleton.Be used to express bone density, have higher accuracy and comparability.
The present invention also can comprise and sets up the clinical diagnosis standard step: as a kind of clinical diagnosis technology, it is nonsensical providing individual bone density value merely, finally will make whether there is unusual judgement according to crowd's normal value.This just need organize the census of population, carries out normal value statistics, and according to the relevant criterion and the suggestion of World Health Organization (WHO) and Chinese osteoporosis committee, the inspection method of the same type of comparing is set up the osteoporosis clinical diagnosis standard of present technique.
The present invention can comprise that also making clinical scale diagnoses, and writes, exports diagnosis report: above basic process has been arranged, just can finish measurement, made diagnosis, sent diagnosis report.Preserve statistical correlation data result: be clinical examination and clinical research requirements of one's work.Set up quality control, to guarantee the stability and the reliability of system: guarantee the accuracy of technology, repeatability, stability, reliability must be carried out regular inspection to measuring system by service property (quality) control phantom, and check and correction is adjusted and is proofreaied and correct.Above each key element has been arranged, just formed a complete bone density measurement and diagnosing osteoporosis technology.
