Mammography X-Ray Accuracy Control Tool

This versatile phantom is ideal for routine quality assurance(QA) of both digital and analog  mammography. It is designed to correlate technical and clinical image quality. It can also be used as a QA tool for digital tomosynthesis. A single exposure captures all the data required for image evaluation. After exposure , the included software performs automatic evaluation, allowing QA personnel to conduct tests effortlessly.

Another key feature of the QUART mam/digi EPQC is the incorporation of a Landolt ring, which mimics the structure of gold. This Landolt ring is used to evaluate low contrast and the limits of perception, and is considered superior to other objects used for simulating calcifications.

The Landolt evaluation of the mammography/digital phantom, which took effect in May 2017, has been accepted nationwide in Germany as a substitute for the CD mammography test.

This phantom is used for QA/QC in stereo biopsy systems on digital or analog mammography devices. It is optimally designed to support all image formats and fields of view (FOV) starting from 40×40 mm. Since the evaluation objects are standardized, comprehensive QA/QC testing is possible. All evaluation parameters required for QA/QC can be obtained with a single exposure.

This phantom is also required as a test device for equipment used in international mammography screening programs. Furthermore, by using the QUART Q-Vision (see bottom of page), you can verify actual low-contrast characteristics. Low-contrast resolution allows you to determine the limits of the perceptible range and provides a reliable basis for more accurate calibration.

Designed for use in QA/QC testing with film-based mammography systems. All parameters required for evaluation can be collected in a single exposure. Complies with IEC 61223-3-2, DIN 6868-7, DIN 6868-152, and Part 1 of the “European Quality Assurance Guidelines for Mammography Screening” (EPQC).

• Size: 240 x 180 x 46 mm

Consists of five PMMA sheets of varying thicknesses. Used to test the automatic exposure control function
of mammography systems in accordance with IEC 61223-3-1.

• Size: 240 x 180 mm

This is a set for measuring the compression force of mammography systems.It complies not only with IEC 61223-3-2 and 61223-2-10 but also with DIN 6868-152 and 6868-7 standards. The test set consists of a foam block, a compression gauge, and a measuring tape.

The QUART Focal Spot Test is designed to visualize the focal position along with the associated density distribution within the field of view of digital or film mammography images. It allows you to verify the extent to which the focal position affects the image quality of the device within the relevant range.

Used to check contact between the cassette and the film. Density variations on the developed film allow you to verify whether screen contact is correct. The test tool features an open space for measuring optical density (OD).
