Laser Radar for Medical Diagnostics: Breakthrough Tests at TUM with Ommatidia’s Q2 System

Munich, Germany | May 13, 2025 — Ommatidia recently demonstrated the capabilities of its Q2 Laser Radar for medical diagnostics at the Technical University of Munich (TUM). This innovative system enables non-contact monitoring of patients with conditions like abdominal aortic aneurysms, providing high-resolution, real-time data without the need for physical sensors.

Why Laser Radar for Medical Diagnostics Changes the Game

The Q2 Laser Radar system, previously used in aerospace and industrial metrology, is now showing promise in medical diagnostics. Its ability to map and measure biological vibrations from a distance can transform early disease detection and patient monitoring.

This initiative builds on Ommatidia’s Q2 product capabilities, which already offer industry-leading precision. Now, we are unlocking its potential in clinical environments.


Test Setup: Simulated Aneurysm Monitoring at TUM

During the workshop, a gelatin-based abdominal phantom was created to mimic human tissue. A simulated blood pressure waveform drove mechanical vibrations within this “belly,” and the Q2 system measured the vibration field in real time.

Key outcomes:

  • Contactless setup completed in under 15 minutes

  • Clear peak frequencies identified at 4.5 Hz, 8.5 Hz, 12.5 Hz, 19.6 Hz, and 74.5 Hz

  • Velocity time series and FFT maps provided full-field spectral insights

  • Spray paint improved surface reflectivity, boosting intensity measurements

The Q2 Laser Radar captured all relevant data with micron-level precision, validating its use in tracking vascular dynamics.

Follow-Up at Ommatidia: Human Arm Trials

To extend the experiment, our team performed additional scans at Ommatidia’s facilities using a live human arm.

We conducted:

  • A 2-second step scan across the arm’s width

  • A 30-second single-line scan for continuous spectral data

These trials showed that laser radar for medical diagnostics can detect subtle vibrations associated with vascular flow, muscle response, and tissue behavior—all without touching the subject.

Practical Benefits in Clinical Settings

Laser radar systems like the Q2 bring numerous advantages to healthcare:

  • Fast Deployment: Setup and scan complete in 15 minutes

  • Non-Invasive: No need for gels, wires, or wearable sensors

  • Broadband Analysis: Captures data from 0.5 Hz to over 100 Hz

  • High Portability: Weighs less than 7 kg and tripod-mountable

  • Open Data Format: Compatible with MATLAB, Python, and clinical post-processing

With these features, clinicians can screen patients without discomfort or risk, making it ideal for ICU monitoring, outpatient diagnostics, and even field-based care.

Fragen zur medizinischen Vibrometrie-Forschung

Was wurde bei der medizinischen Vibrometrie-Demonstration an der TUM getestet?

Die veröffentlichte Machbarkeitsarbeit nutzte ein Gelatine-Bauchphantom, das mit einer simulierten Blutdruckwelle angeregt wurde. Q2 erfasste berührungslos Geschwindigkeits-Zeitreihen und vollflächige Spektralkarten. Ein späterer explorativer Armtest nutzte einen zweisekündigen Stufenscan und eine 30-sekündige Linienmessung.

Welche Frequenzen wurden im Phantomversuch beobachtet?

Der beschriebene Aufbau zeigte Spitzen bei 4,5, 8,5, 12,5, 19,6 und 74,5 Hz. Dies sind Beobachtungen für dieses Phantom, die Anregung und den optischen Aufbau; sie sind keine etablierten klinischen Biomarker und dürfen nicht auf Patienten verallgemeinert werden.

Belegt dies ein klinisch validiertes Diagnoseverfahren?

Nein. Die Arbeit zeigt die Messbarkeit an einem Phantom und in einem explorativen Versuch am menschlichen Arm. Sie belegt weder diagnostische Genauigkeit noch klinischen Nutzen, Zulassung oder Leistung in Patientengruppen. Die Ergebnisse sind als technische Forschung im Machbarkeitsstadium zu verstehen.

Was ist vor einer klinischen Studie erforderlich?

Ein Studienplan muss medizinische Fragestellung, Referenzmethode, Population, Protokoll, Wiederholbarkeit, Bewegungskontrolle, Grenzen des Oberflächenrücksignals, Sicherheit, Ethik und Zulassungsweg definieren. Vorab festgelegte Endpunkte und Unsicherheitsanalyse sind für den Vergleich mit klinischen Referenzen nötig.
