Electronic X-Ray Ruler for Field and Fan-Beam Measurement
Digitisation in x-ray technology makes traditional screen-films less available. Originally, they were used for checks on X-ray beam properties. Today, the QUART nonius performs the same task. And it provides even more substantial features. The QUART nonius can be used to verify if the light visor matches the actual X-ray field. In addition, the nonius provides the option to assess the position and width as well as the dose profile of fanned X-ray beams. For that purpose, it features markings to line-up the light field or positioning lasers. Recent studies have proven that QUART nonius can also be used for field measurement in radiation therapy applications.
