X-Lite |
The X-LITE is the QA tool for fast and precise light field alignment checks which have to be done, according to national and international recommendations, at least once a week and should correspond to within +/- 2 mm at SSD 100 cm.
The X-LITE consists of a fluorescent plate that is activated by ionizing radiation, producing a green fluorescence which is clearly visible for a few minutes after the radiation is switched off. The active areas are permanently marked with field scales in centimeters. A protective red filter prevents activation of the phosphor by the light field from the gantry head or by ambient light. Irradiation photons and electrons penetrate the filter to activate the plate.
