CR and DR Performance Test Phantom

German IBA DIGI-13 CR and DR Performance Test Phantom

The German IBA DIGI-13 CR and DR Performance Test Phantom is used for quality testing of CR and DR imaging systems (including uniformity, spatial resolution, low-contrast resolution, calibration of visible and X-ray fields, artifacts, etc.).

DIGI-13 CR and DR Performance Test Phantom Product Introduction:

According to the DIN 6868-13 standard, it is used for quality testing of CR and DR imaging systems (including uniformity, spatial resolution, low-contrast resolution, calibration of visible and X-ray fields, artifacts, etc.).

On a 1 mm thick copper base plate (300 x 300 x 1.0 mm), there are:

1. Dynamic step wedge, featuring 7 steps with different radiation absorption coefficients: 0.00, 0.30, 0.65, 1.00, 1.40, 1.85, and 2.3 mm copper thickness dynamic range.

2. Low-contrast test objects, consisting of aluminum disks with a diameter of 10 mm, producing contrast levels of 0.8%, 1.2%, 2.0%, 2.8%, 4.0%, and 5.6% at 70kV.

3. Resolution test (line pair card): tests spatial resolution from 0.6 to 5.0 Lp/mm, with a 45° rotation design.

4. Marked areas for signal standardization and uniformity testing.

5. Alignment marks for different cassette sizes.

Patient Equivalent Attenuation Phantom

The patient equivalent attenuation phantom is made of 25 mm pure aluminum material and is used to simulate abdominal thickness conditions of patients. It is used in conjunction with conventional radiography, fluoroscopy, and CR/DR imaging test phantoms.
