X-ray imaging equipment

Abstract

The invention provides X-ray imaging equipment. The X-ray imaging equipment comprises an array X-ray source, a collimator and an X-ray flat panel detector, wherein the array X-ray source is used for emitting array X-ray beams; the collimator is used for collimating the emitted array X-ray beams and irradiating the collimated array X-ray beams to a test object; the X-ray flat panel detector is used for receiving the array X-ray beams penetrating through the test object, and an X-ray photography image is formed by utilization of the received array X-ray beams. By the adoption of the combination of the array X-ray source and the collimator, the X-ray beams approximating parallel and an area source is formed, and it is avoided that as hand bone images are easily overlapped, judgment of a doctor on the bone age is affected; compared with an ordinary X-ray DR technology, as the distance between the hand and the X source is not increased, the size of the whole equipment is reduced, and portability is improved; unnecessary radiation is reduced, and therefore injury to human health is reduced.

Description

technical field [0001] The invention relates to the technical field of nuclear imaging, in particular to an X-ray imaging device. Background technique [0002] The changes in the development of human bones are basically similar, and the development process of each bone has continuity and stages. Bones at different stages have different morphological characteristics, therefore, bone age assessment can more accurately reflect the level of growth and maturity of an individual. It can not only determine the biological age of children, but also can understand the growth and development potential of children and the trend of sexual maturity early through bone age: the adult height of children can also be predicted through bone age, and the determination of bone age is also helpful for the diagnosis of some pediatric endocrine diseases. Great help. Bone age was first used in medical research and to measure the growth and development of children, and then it was widely used to det...

Problems solved by technology

The structure of ordinary X-ray DR is as follows figure 1 As shown, it includes a point X light source 1, an irradiated object 2 and a flat panel detector 3, which has the following disadvantages: (1) Using a point X light source 1 makes hand bone images easy to overlap, thus affecting the doctor's assessment of bone age. (2) In order to avoid image overlap, the distance between the irradiated object 2 and the point X light source 1 is increased, resulting in a larger volume of the entire photographic equipment, which is not conducive to carrying; it increases the radiation dose and increases unnecessary radiation, which increases the damage to human health, especially for children
