ABI and much more
Fast and easy simultaneous 4-point assessment of oscillometric Ankle-Brachial-Index (ABI), Pulse Wave Velocity (PWV) and Pulse Wave Index (PWI™).
TBI optical add-on module
Use 2 additional optical PPG probes to determine Toe-Brachial-Index (TBI) and Toe Pressure.
A comprehensive ABI measurement system to efficiently assess Peripheral Artery Disease (PAD), in line with guideline recommendations.
macOS and Windows
The AngE Software offers precise analysis and works natively both on macOS and Windows computers.
Why it's important to
early diagnose Peripheral Arterial Disease (PAD):
PAD affects 12-14% of the world's population.*
Up to every other PAD patient does not experience symptoms and is likely not diagnosed.*
die within 4 years
Only 50% of PAD amputees survive more than four years.*
Simultaneous recording on all limbs.
Apply Pulse Volume Recording (PVR) on all limbs at the same time to quickly determine the slightest side differences.
The oscillometric ABI, Pulse Wave Velocity (PWV) and Pulse Wave Index (PWI™) will be automatically calculated during the test.
Use the build-in Exercise Stress-Test to detect variations pre and post provocation.
Optical TBI Add-On
Systolic Toe Pressure, TBI and Skin Temperature.
Add two optical pulse volume sensors to assess toe pressure and temperature differences as well as to calculate the oscillometric TBI in one test.

One-page overview report.
Get all calculated parameters and pulse wave recordings on a one-page printable PDF report.
All at a sight.
Use your custom clinic logo and contact details to ensure a seamless branding towards your patient.
Add even more test applications.
The AngE™ ABI+ system is designed to be as modular and extendable as possible to stay flexible to your needs.
Add various arterial (TOS, Raynaud Syndrome) and venous test applications (such as Venous Reflux PPG, Venous Valve and Muscle Pump test), as well as ECG (for Heart Rate Variability) with our individual upgrade modules.
The database is compatible and you can simply keep on working with the same patient files as before.
Intuitive Analysis Software
Easy application, sophisticated assessment.
Our brand new AngE™ software makes it easier than ever to prepare and conduct the measurements.
The touch-screen optimized user interface is intuitively simple to use and is designed to significantly reduce the learning barrier.
- Runs natively on macOS and Windows computers
- DICOM and HL7 compatible (coming soon)
- PDF export with custom clinic logo
- Direct report comparison
- Supports photo documentation for each test
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.
Benefits of AngE™ ABI+ compared to Doppler probes:
3-Minutes Screening compared to ~10min. Doppler ABI or ~20min. TcpO2 test.
Cuffs measure all Vessels and Collaterals at the same time (compared to one vessel at a time with Doppler).
Direct left and right comparison to detect slightest side differences in timing and amplitude.
Comparable measurements (to detect trends) and reduction of human error. No additional training needed.
