EvokeDx®

Fourier Analytics

Discrete Fourier analysis is used to decompose the complex and repetitive time-based waveform into a spectrum of sinusoidal functions, “frequency components”, each quantified by an amplitude and phase value to be used with a series of Fourier statistical tools.

Patented icVEP Tests

Konan’s patented Isolated Check VEP (icVEP™) is a low-contrast, high temporal frequency, sinusoidally modulated stimulus thought to target the magnocellular pathway.

Very Short Run Testing

EvokeDx features a novel test administration method, “Very Short Runs”, typically 2 to 6 seconds each, enabling easier patient compliance, better staff satisfaction, and ultimately mathematically advantaged in the signal averaging process.

Test Library - 16 strategies

The EvokeDx test library includes both novel and ISCEV standard visual electrophysiology systems.  Grouped by icVEP, VEP, and ERG strategies, simply select the test, the eye(s) being tested, and whether recorded with one or two channels.

Low-cost, Non-Proprietary Electrodes

EvokeDx electrode leads feature standard snap connectors to allow the utilization of high-quality, non-proprietary EEG electrodes that cost significantly less than the proprietary electrodes offered by other vendors.

Contact Konan Medical for a review of how substantial this cost savings really is in your practice.

Clinical Evidence

SBIR Glaucoma investigation reported 94% and 92% accuracy respectively in separating glaucomatous from non-glaucoma patients using the patented icVEP protocol. Independent assessments in June 2013 at two sites in Beijing (TongRen and YouYi) report equivalent findings using icVEP.

Linearized OLED Monitor

Off-the-shelf LCD monitors used by some other companies introduce an undesirable luminance artifact that may contaminate a transient response. Our linearized Organic Light Emitting Diode (OLED) monitor eliminates luminance artifacts while adding microsecond timing.

Integrated Gaze Monitor

EvokeDx utilizes an IR gaze monitor to assist in patient positioning and attention/fixation during the test. A graphical heat map provides the operator with real-time feedback on the monitor while the test is being conducted.

Pediatric Tests

Kid-friendly, video animations are one-touch available to capture the child’s attention and test immediately with our novel “Very Short Run” strategy. This simplifies the lack of attention problems encountered with extended test sequences and re-tests from attention lapses.

Remote Training & Support

Konan products feature “KonanCare”, an integrated remote support tool, to enable secure, permission-based, real-time, onboard training and technical support. Yet another cutting-edge feature designed to enhance support and training while reducing costs and downtime.

Luminance Calibration

A fast and simple luminance calibration feature is included to periodically verify monitor luminance output critical for precision testing. Systems are individually calibrated at manufacture, but all monitors change luminance characteristics over time. We make it easy to maintain optimum performance.

No "IRQ" Synchronization

Our scientists have incorporated a low-latency technique to synchronize data collection as opposed to video-card-based “IRQ” methods. Synchronous data is designed to avoid errors from side-lobe leakage. Automated artifact rejection also simplifies high-quality data collection.
