Detailed Report Printout

The one-page report combines all important details about the patient’s vascular status on a single page at the touch of a button.

Authentic Pulse Wave

By using better pressure sensors and a sophisticated filter algorithm, the system achieves a more detailed and sensitive recording of the pulse wave.

Comprehensive Software

The AngE-System comes with a sophisticated software featuring patient management, measurement analysis, DICOM/HL7 interfaces and many more.


A modular design ensures a tailor-made and future-proof investment.

8-Channel Segmental Oscillography

The simultaneous recording of up to eight channels allows for the localization of occlusions as well as the automated calculation of pulse wave parameters within 45 seconds.

Finger & Toe Pressure

The OPO module allows performing optical pulse oscillography to determine blood flow in fingers and toes as well as to conduct arterial pressure measurements.

Ultrasonic Doppler

The AngE combines ultrasonic probes with pneumatic cuffs to allow Doppler pressure measurements with up to 16 tracks. The Doppler indices can be displayed at a glance on a dedicated overview report.

Venous Air Plethysmography

The Air VVP allows conducting plethysmographic measurements by using cuffs only. The often used mercury-filled strain gauges become unnecessary.

New Scientific Publication

"Time consumption for testing was significantly lower using the semiautomated AngE-device – a finding that is economically important, especially in high volume centers and epidemiologic studies."
– Mayr, Hirschl, Klein-Weigel, Girardi, Kundi; 2019

The high sensitivity of the optical sensors allow for a good documentation of the pulse waves, even with marginal blood flow. Given the virtually unfiltered display of pulse curves, dicrotic waves can be clearly identified for healthy and elastic arteries.

I consider SOT to be the European market leader for D-PPG measurements. The AngE Phlebo is a miniaturized device with high-quality, sophisticated evaluation software.

Prof. Dr. Jaroslav Strejček
President of the Czech Society of Phlebology

The AngE Phlebo is the state-of-art, haemodynamically significant D-PPG system for venous diagnostics. This non-invasive functional investigation has always helped me accurately examine venous disorders, even with complex cases.
