Product catalog summary
Product Description: The M-143 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 49 kV. The anode is made of a molybdenum alloy with a 10° target angle, and it supports nominal focal spots ranging from 0.15 to 0.4, compliant with IEC 60336 standards. This tube is compatible with Varian B110, B112, and B115 housings.
Specifications: The M-143 tube is manufactured by Varian Medical Systems. Specifications are subject to change without notice. The document includes detailed diagrams and charts for single load ratings, filament emission, and anode heating and cooling, all adhering to IEC 60613 standards.
Performance Charts: The document provides various performance charts, including:
  • Single Load Ratings: These charts show the nominal anode input power for a 40% anode heat content, with specific power ratings at different exposure times.
  • Filament Emission Charts: These charts guide trial exposures by detailing maximum kV, tube emission, filament current, exposure time, and target speed.
  • Anode Heating & Cooling Chart: This chart illustrates the time required for the anode to heat up and cool down.
Additional Information: The document includes contact information for Varian Medical Systems in Salt Lake City, UT, and Charleston, SC, and directs users to their website for further details.
