Mammography is a medical technique for detecting breast cancer by irradiating the breast with X-rays. The breast is stretched thinly between two plates, and the X-ray is designed specifically for the breast.

X-rays are easily absorbed by high-density materials and penetrate low-density materials. Therefore, the difference in the X-ray dose absorbed by the breast allows for imaging of the internal tissues of the breast. Mammography is characterized by its ability to capture a wider range of images than ultrasonography and to detect finer calcification.

An X-ray tube is used to generate the X-rays used in mammography, where electrons generated by heating a filament (cathode) are accelerated and collide with a metal (anode) such as tungsten or molybdenum. At this time, X-rays are generated. For this reason, X-ray tubes have a built-in high-voltage power supply for electron acceleration and a filament power supply for electron generation.

Matsusada Precision offers a variety of high-voltage power supplies for X-ray tubes and those with built-in current sources for filament heating.
