Problems solved by technology

[0008] 2) Ordinary film method: shooting the detected image on a chemical film, the observation is time-consuming and laborious, and causes a lot of material consumption, and produces a lot of chemical waste liquid and waste that pollute the environment. In addition, the preservation and transmission of the film are also very difficult. inconvenient
CR uses image boards to store images, and flat-panel DR uses X-ray conversion VLSI to collect images, and the equipment is very expensive

Embodiment 1

[0034] Example 1 as figure 1 , 2 As shown, the digitized bone age instrument in the present invention includes an X-ray generator, a detector 3, a frame 1, a light beam device 6, a support plate 5, a driving device and a control computer.

[0035] Described frame 1 is a cuboid structure, is provided with a support plate 5 near the position of bottom in frame 1, and described support plate 5 is provided with hand model 4, hereinafter referred to as hand model 4, on both sides of frame 1, set The place of the support plate 5 is provided with a detection port, which is used to place the hand of the person to be tested on the hand model 4 through the detection port. The bottom of the support plate 5, that is, the bottom of the frame 1, is set in the direction of the fingers of the hand model 4. Vertical strip detector 3 . The size of the hand model 4 depends on the size of the hands of the detection crowd. In the present embodiment, two hand models 4 are arranged relative to eac...

Embodiment 2

[0042] Example 2 as figure 1 , 2 As shown, similar to the overall structure in Embodiment 1, only the X-ray tube 2 and related connections are different, the position of the X-ray tube 2 is fixed on the frame 1, the driving device is connected with the beam The optical device 6 is connected, and the optical device 6 is controlled to rotate back and forth with the X-ray tube 2 as the center, so that the emitted linear light source swings back and forth along the finger direction of the hand model 4, and is synchronized with the moving direction and speed of the detector 3 , irradiating on the detector 3 .

[0043] When X-ray irradiation detection is needed, first let the hand of the subject be placed on the hand model 4 of the support plate 5, and then, under the control of the control computer, start the high-voltage generator to energize the X-ray tube 2; When the tube is ready for exposure, start the driving device to drive the beamer 6 to rotate back and forth around the ...

Abstract

A digitalizing method and device for measuring the bone age features that a line scan technique is used to scan the various positions on human body in moving mode and the obtained scanned images can be further processed by computer. Its advantages are high sensitivity and efficiency, wide range, and low cost.

Description

technical field [0001] The invention relates to a method and a device for digitally detecting bone age. technical background [0002] Skeletal age, referred to as skeletal age, is determined by the degree of bone calcification. In the process of human growth and development, the skeletal system is the easiest to truly reflect the growth time. Bone age plays an important role in the analysis and diagnosis of developmental diseases, endocrine diseases, developmental disorders, nutritional disorders, genetic diseases and metabolic diseases. [0003] Judgment of bone age mostly use X-ray film. Generally, the effect of detecting the wrist is the most ideal. Because there are a large number of long bones, short bones and round bones here, which reflect the growth and maturity of the bones in the whole body, they are easy to detect and cause the least damage to the human body. Sometimes X-rays of the elbow, knee, ankle, and head can also be taken as needed. [0004] Judging the...
