Radiography test phantom QUART SPdigi

general purpose

The QUART SPdigi phantom is designed to be used for QA/QC in radiography and fluoroscopy at x-ray equipment featuring digital storage screen (CR) or CCD image detectors (DR). The phantom does not feature planar grid structures, thus clearly revealing disturbing artefacts whenever present. QUART SPdigi complies with the former DIN 6868-13, DIN 6868-58 as well as IEC 61223-3-1 and IEC 61223-2-11. Technical specifications ENHANCED PHANTOM FORMAT: 330 x 330 cm DESIGN APPROACH: Simplified design for precise artefact detection DYNAMIC STEP WEDGE: 7 Steps; thickness 0 – 2.3 mm SIGNAL NORMALISATION: Homogeneous area in the phantom center, 10 x 10 cm HIGH-CONTRAST RESOLUTION: Line Pair Bar Pattern (Type 38 / Pb 0.05 mm / 45°) LOW-CONTRAST RESOLUTION: 6 Test objects (Aluminium discs; 0.1 – 0.7 mm) X-RAY FIELD ALIGNMENT: Field size markings for all major fields-of-view CENTER: cross-marker, also visible when QUART ZTB beam alignment tool is in use VERTICAL POSITIONING: Wire mount system available for tests of wall-mounted units.
