Radiation/Light Field Analyzer

The Visi-X measures the alignment between radiation and light field and is a proven concept in Quality Control and Service. It is a cassette shaped instrument for checking the light and radiation field coincidence for X-ray equipment. The Visi-X can also be used for checking of the centering of the bucky tray.

Instant Visualization

The Visi-X is based on a after-glowing phosphorus screen. Simply darken the X-ray room and place your Visi-X under the X-ray tube. Adjust the light field and make your exposure. The radiation field will immediately be visualized by the glow of the special phosphor compound. Misalignment down to ±1 mm will be clearly shown on the built-in scales (afterglow will last for several minutes.) No film is needed; therefore, no time is lost going back and forth to the film developer, if there is one.

Protective Daylight Filter

The phosphor is non-radioactive and is covered by perspex plates. A daylight filter protects the phosphor from accidental excitation from light sources. The lifetime expectancy of the phosphor is not affected by light or X-rays having an energy within the recommended range.
