The difference between filter plate and X-ray grid

It is easy to confuse the filter board and the X-ray grid. They have similar names, and they both play a filtering role. The difference between the two is that the filtering objects are different.

What is a filter plate? In the X-ray machine, there is a device outside the X-ray tube called a filter plate. Anything that is invented naturally has its purpose and value. The X-rays generated by the electron bombardment of the target surface are divided into continuous X-rays and characteristic X-rays, and we use continuous X-rays in clinical practice.

Continuous X-rays are like students in all grades in a class. In order to improve the average grade of this class, one way is to filter out those with lower scores (for example, less than 60 points), so there are fewer people left, the quantity is reduced, but the quality is improved.

The principle of the X-ray filter plate is also the same. It filters out the low-energy rays in the continuous wave spectrum and eliminates the softer rays, thereby improving the quality of the rays, making the rays harder and more penetrating.

What is the X-ray grid? The X-ray grid is a device used in the X-ray machine. The function of the filter plate is mentioned above. It is to filter out the low-energy rays in the continuous X-ray. The X-ray emitted from the X-ray tube is called the original rays. That is, rays that have not yet been irradiated to the human body.

After X-rays are irradiated to the human body, some of the rays are absorbed by the tissues of the human body, and some of them pass through the human body. Among the X-rays that pass through the human body, there are some scattered X-rays.

These scattered X-rays are useless and will reduce the quality of the image. Therefore, if these scattered X-rays must be filtered out, the opportunity for the X-ray grid to show its talents comes.

The reason why the filter plate and the X-ray grid are introduced is that they involve the problem of scattered rays, which will be involved in radiotherapy, especially some measures taken for scattered rays.
