10USP Lossless WirelessFast & Lossless Wireless (standard
range up to 300m) using the Vidisco proprietary packet solution,
the image is stored on the ICU and sent back to the laptop in
packets, ensuring maximum integrity.
Other systems dont have wireless, or use standard protocols
which will simply fail or lose data when RF goes bad.
Long Range (1500m) options available

exposure (one approach, immediate imaging)Prolonged usage of
Isotopes, Increased X-ray life cycleNo chemicals = Save transport
and disposal costsSavings on consumable costs (film, imaging
plates)Additional software tools = Save time & moneyNo
maintenance costs (no moving parts!)Increased POD, improved
analysis (on site)Shorter working times and minimal area shutdown
