QUART nonius Electronic X-Ray Ruler

X-Ray Field & Fan X-Ray Beam Measurement The QUART nonius is an easy-to-use but very sophisticated measuring instrument to verify size and quality of x-ray fields. It can also be used to analyse the properties of fanned x-ray beams. The digitisation in x-ray technology makes traditional film/screens 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...

Applications – Radiology Computed Tomography To evaluate width and dose profiles of fanned x-ray beams in CT, the device is positioned on the patient table towards the rotational direction of the scanner. Only one pass is sufficient to adequately assess the parameters. Minimum Exposure CT: 100 kV / 50 mA / SID 100 cm At mammography installations the nonius is mainly used to check the field alignment towards the thorax wall side. The measuring precision exceeds the one acquired with standard phantoms or other tools. Depending on positioning, the dose rate profile within the radiation field (heel effect)...
