Full Field Digital PhantomModel 085
Specifically designed for assessment of digital system resolution
and verification of CCD stitching
Full Field Digital Mammography systems which utilize CCD technology require test tools to monitor the continuity of "stitching" software.
The CIRS Model 085 phantom provides a series of L-shaped line pair targets from 4 to 12 line pair per mm. These targets are contiguously positioned to cover an 18 x 24 cm area at midplane in a 1 cm thick tissue equivalent slab.
Visual inspection of the resulting image permits quick and definitive assessment of stitching continuity and system resolution.
Additional slabs of tissue equivalent material are available for varying thickness and attenuation values.
