The conventional service life range of 150kV medical X-ray beam collimator

Combined with the technical requirements of the domestic pharmaceutical industry standard YY/T 0129-2007 and the actual operation data of the industry, the conventionally compliant 150kV medical X-ray beam limiter, under the premise of standardized use and regular maintenance, generally has a conventional effective service life ranging from ‌8 to 12 years‌.

High-quality products from mainstream first-tier brands can even operate stably for more than 15 years under the scenarios of low frequency and high-standard operation and maintenance; while some non-compliant, low-quality products may experience performance degradation problems such as light field offset and transmission jamming within 3-5 years, failing to meet the clinical application requirements.

This lifespan range is directly related to the operating characteristics of 150kV: 150kV is the highest conventional voltage for medical diagnostic X-rays. During equipment operation, it is accompanied by higher thermal load and radiation dose. The internal lead leaves, transmission structures and light field indication components of the beam limiter are in a high-temperature and high-radiation working environment for a long time, and the component loss rate is significantly higher than that of beam limiters with lower voltage levels, thus forming unique industry characteristics in its lifespan pattern.
