QUART SP_dl

CR/DR Image Quality Test Phantom

The QUART SP_dl phantom is designed to be used for QA/QC routine testing in Digital and Conventional x-ray applications ranging from DR, CR to Fluoroscopy equipment.

Only one exposure is required to collect all necessary parameters to determine the imaging quality of the x-ray system.

The QUART SP_dl phantom complies with IEC, DIN 6868-150 and DIN 6868-4 as well as IPEM, ÖNORM, PN-EN standards and AFSSAPS regulations.

Genuine Feature: kV Stability Test *

The phantom‘s special feature is an optional kV test object. With it, the generator output stability can be monitored on a regular basis without performing invasive or non-invasive kV measurements. As the kV test object consists of 2 different materials, 2 transition points can be defined for a specific radiation quality. The accuracy of the method is +/-2 kV for a pure visual evaluation. When measured with a luminance meter (digital) or a sensitometer (film/screen), the accuracy of the method will increase to +/- 0.5 kV.
