Test 6: Spatial Resolution (optional)
MAMMOMAT Inspiration 37
SPB7-330.640.01.01.02
Test 6: Spatial Resolution (optional)
Objective
To detect assumed spatial resolution problems in different parts of the detector
Required Equipment
a) Bar pattern phantom (containing line groups with spatial frequencies of 5 lp/mm,
6 lp/mm, 7 lp/mm, 8 lp/mm) applicable for mammography
b) Collimator mountable PMMA phantom
c) Compression plate 24 x 30 cm

4. Mount PMMA phantom close to collimator.
5. Move bar pattern phantom on object table to a position where a problem with the
spatial resolution of the detector is assumed.
6. Mount compression plate and perform compression.
7. Perform exposure.
