Mo target pinyin

The pinyin of molybdenum target is mù b.

The so-called "molybdenum target" means "molybdenum target shooting" and "molybdenum target shooting device is a special line machine". At the same time, in the doctoral thesis of the Second Military Medical University in 2009, only the word "molybdenum target" was used in the whole article, which can confirm that the concept of "molybdenum and palladium" does not exist.

Molybdenum target photography is a common examination method in breast disease examination, which can help doctors find and diagnose breast benign and malignant tumors early.

Mammary molybdenum target:

Molybdenum target mammography, also known as molybdenum palladium examination, is the first choice, the simplest and the most reliable noninvasive detection method for diagnosing breast diseases. The pain is relatively small, the resolution is high, and the repeatability is good. The preserved images can be compared before and after, and are not limited by age and body shape. It has been used as a routine check.

Its characteristic is that it can detect breast masses that doctors can't touch, especially for large breasts and breasts, and its diagnostic rate can reach 95%. For T0-stage breast cancer (clinically negative), only soft X-ray examination can be used for early detection and diagnosis, with diagnostic sensitivity of 82% ~ 89% and specificity of 87% ~ 94%.

Matters needing attention of molybdenum target

The production of molybdenum target must be carried out at high temperature and high pressure, and the purity and good quality of molybdenum sheet should be maintained, otherwise the imaging effect of molybdenum target will be affected. In the process of long-term use, molybdenum targets may produce point and mesh defects. This phenomenon will affect the imaging quality and the service life of molybdenum target, so special attention should be paid when using it.

The use of molybdenum target needs to avoid excessive damage and exposure to wet and corrosive environment, so as not to affect the X-ray output.

conclusion

Molybdenum target is a widely used component in X-ray generator, which has important application value in medicine, industry and other fields. The preparation of molybdenum target needs to be carried out at high temperature and high pressure, and the prepared molybdenum target has the characteristics of high melting point, high density and high thermal conductivity. Medical molybdenum target is mainly used for mammography, and industrial molybdenum target is often used for nondestructive testing. Some problems should be paid attention to when using molybdenum target to ensure the imaging effect and service life of molybdenum target.
