3 .1 .2 .1 Stan dard an d M u lti- sam plin g A lgorith m s
Smart Supra test algorithms define what the patient has to do for a test location to be marked
as seen or missed.
The single stimulus test offers two different algorithms, Stan dard and M u lti- sam plin g.
When your machine was installed one of these algorithms would have been set as the default
within the
Options program.
You can change the test algorithm at the onset of a test by clicking
Standard algorithm
In this algorithm the patient has to miss a flash at each test location twice, or see it once, before
it is marked as missed or seen. Having to miss the stimulus twice before the location is marked
as a miss reduces the number of false positives misses. This algorithm has been part of the
Henson software for many years.
Multi-sampling algorithm
In this algorithm the patient has to miss a flash at each test location twice, or see it twice before
it is marked as seen or missed. This algorithm is new to the Henson 9000 and takes a little
longer, as there are more presentations, but is more robust to response errors and is less
variable.
