Tips for buying Digital Mammography Unit Parts

  1. Digital mammographic radiographic unit screening equipment must meet the minimum MQSA requirements for tube outputs, compression performance, position controls, and reproducibility.
  2. Medical facilities should base their digital mammography unit purchase decision on life-cycle cost, local service support, discount rates and non-price-related benefits offered by the supplier, and standardization with existing equipment.
  3. Suppliers offer digital mammography unit service contracts or service on a time-and-materials basis. This may also be available from a third-party organization. Facilities should carefully consider whether to purchase such a service.
  4. When purchasing a digital mammography unit, performance and reliability are important factors.
  5. A high-frequency x-ray mammography generator will help ensure higher efficiency of operation with a minimum of output ripple. It will also need less space than a conventional generator.
  6. Mammography involves a narrow range of tissue thickness, and therefore 1 kV increments and a range of approximately 22 to 35 kV are necessary.
  7. The digital mammograph system should offer at least 500 mAs and an exposure time of 0.1 second or shorter to avoid unnecessary long exposures.
  8. A rotating anode, which has a higher heat capacity than a stationary anode, should be available to promote longer x-ray tube life and provide a more consistent x-ray output.
  9. AEC provides the appropriate image optical density and x-ray exposure for breast composition and thickness.
  10. Focal spot sizes should be approximately 0.1-0.3 mm to ensure that microcalcifications as small as 200 µm can be detected using x-ray mammography.
  11. To clearly image the smallest micro calcifications, an SID of at least 66 cm is needed.
  12. The complexity of the automatic exposure control is the main difference between digital mammography unit systems. Some x-ray mammography systems control only the exposure time, while more advanced ones control the x-ray spectrum, including the kVp, anode, and filtration. Such digital mammograph systems improve the image quality, especially in larger and denser breasts.
  13. Some manufacturers have developed advanced grids, which are expensive to manufacture but improve the image quality in digital mammographic radiographic units.
  14. Facilities considering the purchase of a stereo tactic biopsy system should consider the number of procedures to be performed and the compatibility with existing equipment.
  15. Film-based digital mammograph units are not recommended because they do not allow real-time guidance. Instead, both dedicated and add-on digital mammography unit systems are equipped with small digital detectors.
  16. Add-on systems may be harder to use because they have more limited motions compared to dedicated digital mammographic radiographic units. Consequently, most of the differences are a matter of user preference rather than clinical efficacy.
  17. In digital detector performance, detective quantum efficiency is an important factor when comparing digital mammographic radiographic units. DQE is directly related to the signal-to-noise ratio that results between detector input and output. The noise generated by the detector and the spatial resolution contributes to the DQE of the system. To reduce DQE, SNR must be reduced; a recommended DQE is less than 20% at 5 lp/mm.
  18. Another important factor when choosing a digital mammography unit is modulation transfer function. MTF refers to the loss of contrast relative to an x-rayed object. As the spatial frequencies in a given image increases, MTF decreases, creating loss of visualization; a 50% MTF at 5 line pairs per millimeter is recommended.
