Philippine customers inquire about grid

DR filter, also known as grid, is made of lead foil (that is, thin lead du strips with a thickness of 0.05~0.1 mm) spaced at a certain distance (0.15~0.35 mm) arranged in parallel or at a certain slope, and used between lead strips It can be filled and fixed through X-ray aluminum, paper or wooden strips, and both sides are supplemented with aluminum or synthetic resin protective layers.
Scattered rays are extremely harmful in X-ray photography. Because of its biological effects, that is, biological cells are inhibited, damaged, or even killed after being irradiated by different doses of X-rays. Therefore, scattered rays make the subject and work Personnel increased unnecessary exposure dose and radiation damage, and increased the contrast of X-ray pictures, and even the possibility of losing useful information. For this reason, it is very important to remove scattered rays in X-ray photography. The grid is designed for this purpose.
When shooting, the grid is placed between the film and the body. The scattered rays cannot pass through the lead gap because of the angle with the lead strip, so most of them are absorbed by the lead strip, which greatly reduces the film or flat-panel detector. The received scattered rays improve the contrast of the image, improve the imaging quality of the X-ray film, and reduce the damage to the human body.
