Features
- Locates test patterns precisely 4 – 5 cm above grid cover or mag stand
- Provides attenuation appropriate for phototiming
- Two orthogonal slots for conventional mammography test patterns
- Two orthogonal slots for digital and digital stereo test patterns
The Mammo Focal Spot Test Stand is designed for easy assessment of mammographic spatial resolution measurements according to ACR, MQSA1 and AAPM TG-4, Report #60. The stand precisely positions the test patterns above the grid cover or mag stand and provides attenuation, which is appropriate for phototiming, while minimizing scatter effects. The test patterns may be inserted or removed by the user. The test pattern scale in line pairs per mm (lp/mm) is printed on the stand. The spatial resolution range of the patterns for conventional mammography is (10.0 … 20.0) lp/mm with increments of 1 lp/mm, and the resolution range of the pattern for digital mammography is (4.5 … 9.5) lp/mm with increments of 0.5 lp/mm.
