Aperture plate allows evaluation of fulcrum and bearing conditions. Lead numerals over a 12 mm depth check accuracy of cut. Copper mesh measures in-depth resolution

This device permits the determination of exposure uniformity, cut-level accuracy and fulcrum stability (pivot-bearing tolerances). It consists of a plastic phantom, a steel aperture plate, and a set of metal spacers 10 and 15 cm long. The spacer set provides precise and reproducible placement of the phantom when evaluating different x-ray systems.

Specifications

The phantom portion contains a helix of 12 lead numbers mounted from 1-12 mm above the base, and four copper mesh strips (1.2 x 5 cm each with 0.8, 1.2, 1.6, and 2.0 holes/mm), all embedded in a 15 x 15 x 2.2 cm plastic plate. The aperture plate (15 x15 x 1 mm) as a 3.0 mm diameter central hole.

Weight: 2 lbs.
