Fast and Precise Alignment

The Visi-X is a fast and precise QA tool for 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 Visi-X with a fluorescent plate helps you to align the accelerator radiation fields on the treatment table quickly and directly. The plate is  activated by ionizing radiation, producing a green  fluorescence which is clearly visible for a few minutes after the  radiation is  switched off.

The 5 x 5, 10 x 10, 15 x 15 and 20 x 20 cm2 active areas are permanently marked with field scales in centimeters

Using Visi-X is Easy, and alignment checks can be part of the daily routine. With the filter in place, align the
light field according to the scale on Visi-X. Put any required build-up material on the plate and irradiate.
Remove the filter from Visi-X and check the radiation field alignment.

It is not necessary to wait for the afterglow to fade between exposures, since the contrast is high as long as
the following  irradiation uses the same dose or  higher.
