QUART Biopsy Phantom

Stereotactic Mammography Test Phantom

The QUART Biopsy Phantom is designed for QA/QC at stereotactic biopsy systems in digital and analog mammography.

Its design is optimised for all common image formats and fields-of-view (FoV) from 4 x 4 cm. The phantom‘s integrated test objects enable comprehensive QA/QC testing.

The Biopsy Phantom allows checks on actual low-contrast properties. Low-contrast resolution can be verified to the perceptibility limit, thus providing a solid base for precise equipment calibration.One exposure is sufficient to acquire all test parameters. The phantom is required to test equipment used in National mammography screening programmes.
