This test object is supplementary to TOR MAS or MAX and provides a more “natural” image which may be preferred by radiographers and radiologists.
One half contains a range of filaments, micro-particles and low-contrast details, representing pathological features in the breast. These are sensitive to the mammographic grey-scale, noise and unsharpness, and can be used to obtain an imagequality “score”. The other half simulates the appearance of breast tissue and contains micro-calcification in addition to fibrous and nodular details.

Contains features:
• 6 groups of multi-directional filaments
• 6 groups of micro-calcifications
• 6 groups of 3, low contrast details groups
