The nominal maximum x-ray tube voltage of mammography x-ray equipment should not exceed 50KV.
Mammography is a common imaging method used to detect breast diseases, and mammography x-ray equipment is a key tool for mammography. In mammography equipment, the X-ray tube is the key component for generating X-rays, and its voltage directly affects the energy and penetration ability of the X-rays produced.
X-rays are a form of ionizing radiation that carries some risk of radiation damage to the human body. Although under normal circumstances, mammography equipment produces relatively low doses of radiation, prolonged or high dose radiation exposure may still cause damage to the body, such as skin redness, inflammation, and DNA damage.
The X-ray tube is subjected to electric current and magnetic fields during operation, which can lead to changes in its internal structure and thus affect its service life. Excessive voltage may accelerate such changes and shorten the service life of the X-ray tube.
Common mammography X-ray devices include digital mammography systems (DR), digital molybdenum mammography (DM), digital breast ultrasound systems, and conventional mammography machines
1. Digital mammography systems (DR): These devices use digital technology to convert X-ray Images are converted to digital images, allowing for faster report generation.The advantage of a DR system is that it can automatically adjust the shooting conditions, such as angle and pressure, to obtain the best imaging results. In addition, the DR system can provide real-time image display, which is convenient for doctors to observe and diagnose.
2, digital molybdenum mammography (DM): this device uses a molybdenum detector to capture X-ray images. the advantage of the DM system is that the imaging quality is high, and can clearly show the structure of the breast tissue. However, the disadvantage of DM systems is that they are relatively complex to operate and require specialized technicians to operate and maintain.
3, digital breast ultrasound system: this equipment combines mammography and breast ultrasound imaging technology, can simultaneously display two-dimensional and three-dimensional images of the breast. The advantage of digital breast ultrasonography system is that it can provide more comprehensive information about the breast, which helps doctors diagnose breast diseases more accurately.
4. Conventional Mammography: This device uses film or an electronic photographic plate to capture X-ray images. Although conventional mammography machines were widely used for mammography in the past, they are gradually being replaced by digital devices due to their complexity, limited image quality and environmental concerns.
