according to ASTM E2737
Duplex Plate Phantom Type 2
for Perfomance Evaluation
and Long-Term-Stability Tests of DDAs
Test Phantom for Long-Term Stability Tests of DDA Systems (DR)
The Type 2 Duplex Plate Phantom enables to test relevant parameters of DDA systems like Basic Spatial Resolution, Contrast Sensitivity, SNR and Signal Level for initial performance evaluation and long-term stability. These test required and described in detail in ASTM E2737 have to be performed periodically for checking process control and lang-term stability

| 15.75 x 11.81 x 0.59 / 1.50 inch |
Advantages of Type 2 compared to Type 1 Duplex Plate Phantom
Hole Type IQI on top plate is located in the center of the plate:
Low scatter radiation and much lower gradient on the IQI
for improved repeatability of contrast sensitivity tests
Free areas beside long side of the Hole Type IQI:
Allowing contrast sensitivity evaluation also at the edge of the IQI
improved repeatability compared to evaluation at the holes of IQI
Region of Interest (ROI) on top plate close to Hole Type IQI:
Lowest gradient in ROI for improved repeatability on SNR and
Signal Level tests
Cut-outs in plastics for ROIs:
ROIs clearly visible on the X-ray image. Easier evaluation
Two Duplex Wire Type IQIs can be inserted:
Portrait and landscape axis can be evaluated in one image
Duplex Wire Type IQIs can be removed:
Use for other applications possible
