Product catalog summary
Product Overview: The M-149 is a rotating anode X-ray tube designed specifically for mammography systems. It features a 2.8-inch (71 mm) anode with a maximum heat content of 222 kJ (300 kHU) and operates at 39 kV. The anode is made of a molybdenum alloy with a 10° target angle and is compatible with Varian B-110 housings.
Specifications: The nominal focal spot size is 0.25 as per IEC 60336 standards. The nominal anode input power is 2.7 kW according to IEC 60613, with an equivalent anode input power of 60 Watts.
Performance Charts: The document includes various performance charts such as single load ratings, filament emission charts, and anode heating and cooling charts. These charts provide detailed information on the operational parameters like maximum kV, tube emission, filament current, exposure time, and target speed.
Usage Recommendations: When using the emission curves for trial exposures, it is recommended to refer to the power rating curves for maximum kV, tube emission, filament current, exposure time, and target speed to ensure optimal performance.
Manufacturer: The M-149 X-ray tube is manufactured by Varian Medical Systems, with specifications subject to change without notice.
