Features
- Checks all relevant parameters of analogue fluoroscopic X-ray installations during constancy tests in one shot
- Suitable for overcouch and undercouch tubes and wallstand installations
- Complies with DIN 6868-4: 1987
The NORMI 4 test object is used for constancy tests of fluoroscopic and indirect radiographic X-ray equipment according to DIN 6868-4: 1987.
The NORMI 4 package includes a structure plate with a copper step wedge, radio opaque concentric rings, a 10 mm grid, a homogeneous field in the centre for testing the optical density or the gray value and a resolution test pattern.
Furthermore, the NORMI 4 package includes assembling parts as well as a 30 mm thick acrylic plate and a 1.3 mm thick copper plate for beam attenuation. The external plate dimensions are 300 mm x 300 mm.
Instead of the acrylic absorber, an optional 25 mm thick aluminum absorber can be fixed to the collimator by using adaptation rails. The entrance dose can be measured with a CONNY II dosemeter.
