Shielding device, shielding method and X-ray inspection device based on light field of light collimator

Abstract

The invention discloses an X-ray shielding device, an X-ray shielding method and an X-ray inspection device based on a light field of a light collimator. The X-ray shielding method comprises the following steps: determining an X-ray inspected area of a subject through adjusting the light field of visible light emitted by an X-ray emitting device; determining a light field area of the visible lightby using a light sensing module to acquire area information; adjusting a shielding plate of the shielding device positioned between the X-ray emitting device and a body of the subject by utilizing the area information, so that the size of a variable light-transmitting port of a shielding device is consistent with the light field area of the visible light, and the phenomenon that the size of the variable light-transmitting port of the shielding device is consistent with an irradiation field area of X-ray is realized. According to the X-ray shielding device, the X-ray shielding method and the X-ray inspection device based on the light field of the light collimator disclosed by the invention, the light field of the visible light is utilized, and the size of the variable light-transmitting port of the shielding device can be automatically adjusted, so that the phenomenon that the size of the variable light-transmitting port of the shielding device is consistent with the irradiation fieldarea of the X-ray is realized; and as for an operator of the X-ray inspection device, operation steps are not added.

Description

technical field [0001] The invention relates to the field of medical radiation protection, in particular to an X-ray shielding device based on the beam field, an X-ray shielding method and an X-ray inspection device. Background technique [0002] X-ray machines are the most commonly used medical imaging equipment in various hospitals. The biggest advantage of the X-ray machine is that it has a very wide range of applications. It can image almost all human tissues, such as bones, skulls, chest lungs, joints, etc., and it is very convenient to use, and the imaging time is short. The requirements for equipment operators are also relatively low, and the purchase and maintenance costs are also relatively low. In contrast, ultrasound equipment cannot perform bone, head, chest and lung examinations; although MRI can also examine most human tissues, the equipment is large, costly, takes a long time, and has a relatively low spatial resolution. But the X-ray machine also has its ob...

And if it is necessary to take a chest film, the operator of the X-ray machine will use the beam device that comes with the X-ray machine to limit the X-rays to only irradiate the chest of the subject.

Although only the subject's chest will be directly exposed to X-rays, X-rays will have a lot of scattered X-rays during imaging, and these scattered X-rays will be exposed when the X-ray protection is not in place. Scatter to the subject's eyes, skull, lymph, gonads and other parts that are very sensitive to X-rays, thus adversely affecting the health of the subject
