Earlier this year Difra Instrumentation, a leading global manufacturer of VNG diagnostic equipment, released their new VisioX D2 module to power the oculography portion of the VNG test. The oculography tests include smooth pursuits, random saccades and optokinetic nystagmus tests.  These tests are important for evaluating the central nervous system.  

Previously, the Difra oculography tests were powered by their Visiobox module.  Essentially, Visiobox was a micro-computer that helped power the tests so you would not have buffering or freezing of the screen image.  It did a very good job, but it was additional hardware for the VNG diagnostic equipment.  Plus, it has to connect to the computer via either a WiFi connection or ethernet connection. 

The problem with a WiFi connection is in some occasions the connection was too erratic to be effective, causing images to freeze or heavily buffer resulting in a potential retest.  To eliminate that possibility in almost all instances, we set up the VNG testing systems using the ethernet connection.  This adds another cable to the VNG device, but it eliminates the need for a WiFi connection and the aforementioned problems associated with it.

In the interest of always trying to improve their products, Difra developed the VisioX D2 to eliminate the Visiobox and all of the connecting cables while improving even further the oculography results.  As a result, we only use high-speed gaming laptop computers.  Each of these gaming computers utilizes NVIDIA mobile graphics cards with their own internal memory. Typically, we use HP Pavillion 16.1" gaining laptops.  Each has a minimum of 8 GB of RAM and generally 1TB of hard drive space. We also specify Intel Core processors, which makes for a very fast, powerful system with no freezing or buffering and fewer cables.  Thus the system is very reliable and stable. 

What if you have an older Difra VNG, can you update it to the new VisioX D2?  In most cases yes, you can. All you will need is the correct gaming computer and the new version of the Difra software. You'll achieve faster performance, eliminate your Visiobox hardware, and receive excellent results by upgrading today.  Give me a call to discuss your system and what is involved and what your cost would be to upgrade your Difra VNG system.   I think you will be impressed with the results.
