NORMI^® 13

The NORMI 13 test object is designed for constancy tests of X-ray equipment with a digital image intensifier or plate. It includes a structure plate with radiological visible line marks for the light field adjustment and the test of the light field/ radiation field congruency, a gray scale test, a low-contrast test, a line group resolution test pattern, an area for entrance dose measurement and homogeneous areas for homogeneity tests and signal normalization.

The structure plate is used in combination with a 30 mm thick acrylic attenuation plate or a 25 mm Al plate to simulate patient absorption. The external dimensions of the plates are (300 x 300) mm.

Key Features

• Checks the relevant parameters of digital X-ray equipment (DR and CR systems)
• Suitable for constancy tests in digital radiography
• For use with an attenuation plate for patient simulation and a dosemeter for entrance dose measurement
• Complies with DIN 6868-13
