The role of large and small focus in DR photography

Newheek-Uarm 4月 24, 2022

Do you know the role of large and small focal points in DR photography? Large focal points can withstand larger beam currents, and large beam currents produce X-rays with sufficient brightness. The large focal point is often used in occasions that require large brightness, such as filming. Using a large beam with a large focus can shorten filming or imaging time. Dual focus X-ray tubes have a large focus, which is also required by the tube manufacturing process. Because in the exhaust process of the bulb, it is necessary to obtain enough anode power to bombard the superficial gas in the anode metal, the power of the small focus is not enough, and the power density is too high and the target will melt. So with a big focus, you can get enough anode power to help exhaust with a lower power density. The image quality of the large focal point is not good enough. For higher resolution images, the bifocal X
Ray tubes usually have a small focal point. Everyone here understands the role of large and small focus in DR photography. If you have any other questions, please call us.
