Data Points Analyzed

Proprietary intelligent algorithms delivering objective brain function insights.

How it works

ACTIVATE. READ. GUIDE.

Three simple steps. One objective readout of brain function.

A single magnetic pulse stimulates a targeted brain network. Electrophysiological recording captures the brain's response in real time. Proprietary intelligent analytics transform those signals into an objective, physician-ready assessment of brain function.

ACTIVATE

Targeted Brain Stimulation

A brief, high resolution focused magnetic pulse stimulates a selected brain network.

1

READ

Capture the Brain's Response

The system captures the brain's electrophysiological response over the next 300 milliseconds, revealing how effectively the stimulated network responds and communicates.

2

GUIDE

Turn Signals into Clinical Insight

Millions of brain-response data points are analyzed using QuantalX's proprietary intelligent algorithms and compared with an FDA-reviewed age-matched normative database, generating an immediate, physician-ready report.

Reading the Delphi-MD™ Output

Normal

The measured brain signature closely tracks the age-matched reference waveform. Cortical reactivity and connectivity fall within the normative range for the patient's age group.

Abnormal

The measured brain signature diverges from the age-matched reference. Lower amplitude and delayed peaks indicate reduced network reactivity relative to the reference population.

Understanding
Your Brain Starts Here.

When it comes to your brain, having answers can change everything. Delphi-MD™ provides objective insight into how your brain is functioning, helping you and your physician better understand your brain health and move forward with greater clarity and confidence.

*All clinical interpretations of Delphi-MD™ assessments must be made by qualified healthcare professionals within the context of a full patient evaluation. The Delphi-MD™ system is intended to elicit, record, and analyze TMS-evoked brain potentials (TEPs) and provide quantitative output parameters compared against a normative reference database limited to ages 50–75. Adverse events during or after evaluation may include headache, nausea, dizziness, fatigue, insomnia, anxiety/agitation, back or neck pain, vomiting, tinnitus, migraine aura, and abnormal sensations. Delphi-MD™ is not intended to be relied upon solely to make or confirm a diagnosis. For more information, refer to the Delphi-MD™ user manual.
