This versatile phantom can be used for monitoring technical parameters of digital mammography imaging systems according to the requirements of the ”European Guidelines for Quality Assurance in Mammography Screening” and IEC 61223-3-2.
It can be used to test:
- optical density / luminance in the reference point
- spatial resolution
- threshold contrast visibility
- contrast
- effective radiation field
- automatic exposure timer
- CNR, SNR
- NPS
- MTF
- ghosting
- filaments
- artefacts evaluation
- geometric distortion check
- contrast details
Technical data (can be modified to customer specifications):
- dimensions: 240 x 180 mm or 300 x 240 mm
- modular construction – different modules can be firmly placed on the main module
- optional carrying case (03-322)
