The QUART mam/digi EPQC phantom is designed to be used as a versatile tool for QA/QC routine testing in Digital and Analog Mammography. It creates a link between technical and clinical image quality. It can also be used as a QA tool for Digital Tomosynthesis.
Only one exposure is required to collect all necessary parameters to evaluate the imaging quality. After the exposure, the image can be visually checked or automatically evaluated through the unique QUART MammoPro software module. The QUART mam/digi phantom incorporates Landolt ring objects which is similar to gold structures. This Landolt's ring is used to evaluate low contrast and perceptual limits and is considered to be superior to other objects used for simulated calcification.

The Landolt Rating of the Mammo / Digital Phantom, which came into force in May 2017, was accepted nationwide in Germany as a substitute for the CD mammography test.

The QUART Biopsy Phantom is designed for QA/QC at stereotactic biopsy systems in digital and analog mammography. It is designed optimally for all common image formats and fields-of-view(FoV) from 4 x 4 cm.
The phantom is an integrated test object and enables comprehensive QA/QC test. One exposure is required for all necessary test parameters for QA/QC.
This phantom is required as test equipment in the international mammography screening program.
Also the QUART Q-Vision Phantom/Dose meter combination (see below), 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.

It is a film system mammography and it is designed for QA / QC test. One exposure is required to correct all necessary parameters.
It complies to IEC 61223-3-2, DIN 6868-7, DIN 6868-152, and "European quality guarantee guidelines in mammography screening" (EPQC) Part 1.

• Size: 240 x 180 x 46 mm

It consists of five PMMA sheets with different thicknesses. It is used for testing the automatic exposure control function of mammography equipment according to IEC 61223-3-1.

• Size: 240 x 180 mm

A measurement set for the compressive force of mammography systems. It complies to IEC 61223-3-2 and 61223-2-10 as well as DIN 6868-152 and 6868-7 standards. The test set consists of a form block, a compression gauge, and a measure.

The QUART Focal Spot Test is designed to visualize the focal position with the associated concentration distribution within the digital or film mammo image. It is possible to check how much the focal position within the relevant range will affect the image of the device or not.

It is used to check the contact between the cassette and the film. Due to density fluctuation on developed film, it can be confirmed whether screen contact is correctly done. The test tool has open space for optical density (OD) measurement.
