X-ray mammographic tube assembly IRM-69

The X-ray tube assembly is designed for installation in the production of new medical mammography devices, as well as for installation in compatible devices in case of replacement of the tube assembly during repair and maintenance of in-service mammography devices.

These X-ray tube assemblies are available in several configurations. Different X-ray tubes can be used:

– with molybdenum anode

– with tungsten-rhenium-molybdenum anode

Radiator housings can have:

lateral HV and LV sockets
coaxial HV and LV sockets
