DuplexABI: vascular testing and duplex ultrasound in one point-of-care system
ABI Finds It.Duplex Defines It.
From physiologic assessment to anatomic and hemodynamic insight. DuplexABI™ pairs the vascular testing clinicians already run on VasoGuard® with duplex ultrasound imaging in a single portable platform.
One System. Two Powerful Tests.
One Complete Vascular Picture.
Physiologic to Anatomic.
See What ABI Alone Can't.
Two Exams. One Operator Position.
For a decade, the physiologic vascular lab and the imaging vascular lab have been two rooms, two instruments, and often two appointments. DuplexABI™ closes that gap with one workflow that runs from screening through anatomic and hemodynamic characterization.
ABI Finds It.
Physiologic assessment on the VasoGuard® platform
- Doppler ankle-brachial index (ABI)
- PPG toe-brachial index (TBI)
- Segmental pressures and PVR waveforms
- Wearable PPG sensors
- CuffMatch™ cuff-air-volume verification
The question it answers: is lower-extremity perfusion reduced?
Duplex Defines It.
Anatomic and hemodynamic imaging at the same cart
- B-mode anatomy and plaque visualization
- Lesion location and vascular anatomy
- Peak systolic velocity and velocity ratios
- Flow pattern analysis
- Degree of stenosis and disease severity
The question it answers: where is the lesion, and how severe?
What the Operator Sees
The imaging modes at the heart of the duplex exam, in Terason's own example scans.
B-Mode. Grayscale anatomy: the structural image every duplex exam builds on.
Representative Terason imaging examples. Also supported: Power and Directional Power Doppler, Continuous-Wave Doppler, and Tissue Harmonic Imaging.
The Handoff Happens at the Same Cart
Doppler ankle-brachial index and photoplethysmographic toe-brachial index are the right first test. They are fast and non-invasive, and they answer the question of whether lower-extremity perfusion is functionally reduced.
Every abnormal or inconclusive result tells the clinician that something is wrong. None of them says where the lesion is, how tight it is, or whether it explains the patient's symptoms. Historically, that handoff has meant scheduling the patient back for a separate duplex study. With DuplexABI™, the follow-on study happens at the same cart instead of at the next appointment.
"DuplexABI reflects exactly how CorVascular thinks about product development: practical innovation built around real clinical workflow. When vascular specialists are asked to perform an ABI assessment and a lower extremity duplex exam for the same patient, they need a solution that is efficient, portable, and easy to use. DuplexABI is designed to support both exams in one streamlined point-of-care workflow."
ABI / TBI Interpretation Categories
Interpretation categories per the 2016 AHA/ACC Lower Extremity PAD Guideline.
The DuplexABI™ Pathway
From the first index to a defined lesion, without leaving the cart.
Physiologic Assessment
Doppler ABI and PPG TBI. Functional evaluation of lower-extremity perfusion.
Abnormal or Inconclusive Findings
Results that trigger further evaluation.
Suspected Arterial Disease
Reduced perfusion suggests possible stenosis or occlusive disease. Localization and severity still need to be defined.
Duplex Ultrasound
Anatomic and hemodynamic insight. Defines the lesion and its significance.
Clinical Confidence
Actionable information for diagnosis, treatment planning, and follow-up.

The Platform Clinicians Already Know
Built on the VasoGuard platform, the physiologic half of DuplexABI™ is the system clinicians already know. Segmental pressures, PVR waveforms, wearable PPG sensors, and CuffMatch™ cuff-air-volume verification all carry over unchanged.
The imaging half is integrated into the same cart and the same operator position. Two cart configurations share the same clinical capability and differ in footprint and screen size, so a facility can match the system to the room it actually has.
Available now. Both configurations are built and supported in Minnetonka, Minnesota alongside the rest of the VasoGuard line, and CorVascular is accepting orders and scheduling demonstrations today.
Existing VasoGuard customers: contact CorVascular about adding DuplexABI™ to your lab.
Cart Engineering
- Dedicated linear array probe holder
- Secured cable management
- Quick-release computer mount for service
- Slimmer, lighter cart that moves cleanly through crowded corridors and small exam rooms
- Two configurations sharing the same clinical capability
Developed in Collaboration with Terason
CorVascular developed DuplexABI™ in collaboration with Terason, combining CorVascular's vascular diagnostic workflow expertise with Terason's established ultrasound capabilities. The result is a solution tailored for vascular specialists who want a more versatile approach to peripheral vascular assessment at the point of care.
"CorVascular understands the needs of the vascular market and how to translate those needs into meaningful workflow solutions. We are pleased to collaborate on DuplexABI and to help bring this new solution to clinicians looking for more efficient ways to integrate vascular testing and ultrasound in practice."
