1.6.2.3 Volista VisioNIR (VSTII only)
Fig.11: Volista VisioNIR function
The Volista VisioNIR function is used to filter out the residual near-infrared rays from the LED
spectrum in order to keep them at very low levels. Volista VisioNIR is suitable for use with near-
field infrared cameras, without disturbing the signal transmitted to the monitor. Volista VisioNIR
can be used during surgery using ICG (indocyanine green), as well as by taking advantage of the
natural property of certain tissues, which emit fluorescent light following stimulation (autofluores-
cence). In this case, the detection area of the fluorescence camera must have a wavelength
greater than 740nm (see Table35).
NOTE
It is recommended to first test the NIR imaging system and the fluorescent dye with
the Volista VisioNIR function in order to optimise the settings.
