Streamline DVT Clinical pathway with AI

ThinkSono Guidance enables any healthcare professional to perform Deep Vein Thrombosis (DVT) ultrasound scans at the point of care. It uses AI to guide the user through a 2-region compression ultrasound examination.

Note: To use ThinkSono for training purposes go to “Ultrasound AI – Training”

ThinkSono Guidance has a CE Class IIb regulatory approval and is available in the EU/UK only. Not available in the U.S (FDA clearance pending).  The above video is for demonstration purposes only, actual user interface may be different.

What is DVT

Deep Vein Thrombosis (DVT) is a blood clot within the deep veins of the leg. This can be potentially fatal if parts of the clot breaks off, travels through the body and becomes lodged in the lungs – this is called a pulmonary embolism (PE).

The Problem

While DVT and PE combined are the number one cause of preventable hospital death, the current diagnostic pathway is slow and inefficient. Patients often wait hours or days for test results.

AI Solution

ThinkSono Guidance enables non-ultrasound trained healthcare professionals to collect DVT exam data for a qualified clinician to review. This can improve the clinical pathway significantly. A ThinkSono Guidance exam typically takes less than 15 minutes using only a compatible handheld device and a mobile phone.

How It Works

Conduct a compression ultrasound DVT exam with live AI-guidance. Intuitively identify the correct anatomy and probe positioning, allowing fast and accurate data collection without direct oversight.
Upload the collected exam data to the Cloud Dashboard for rapid interpretation by a qualified clinican.
Qualified clinicians can quickly data via automated templates and digital communication features. Spend less time on documentation, and more time caring for patients.

Use Cases

ThinkSono in Action

Ultrasound is the least invasive and most portable imaging modality in medicine. Although it is a life saving tool, access is extremely limited, negatively impacting outcomes for millions of patients.

Emergency Rooms

ThinkSono Guidance enables healthcare staff to scan patients on arrival & send the captured images & clips to qualified clinician for review to potentially reduce and/or removing burden on specialist sonographers.


In the UK, ThinkSono’s technology is can potentially be used as a core component of a redesigned community DVT pathway that includes rapid assessment in primary care settings.

Patients can be scanned locally by their GP without specialist equipment, removing the need to travel to a hospital and/or book multiple appointments.

Point of Care / Bedside

ThinkSono Guidance is being used on medical wards to assess patients for DVT, potentially eliminating the need to transfer complex patients to the ultrasound service.


DVT is a significant problem for the NHS. Not only from a financial perspective, but also a clinical perspective…Pathways for DVT is consequently very time consuming because the patient has to be sent to radiology for the performance of the scan. Enabling nurses, GP’s and other non-specialists to diagnose DVT accurately at the point of care would be extremely useful for the NHS and much more convenient for patients.

The burden of deep vein thrombosis is significant for the National Health Service and one particular problem is that a DVT is suspected much more often than it is found. Potential for non-experts to perform diagnostic ultrasound could dramatically improves DVT diagnostic pathways.

I’m excited about this technology and can see many applications for it. For example, rehab units and nursing homes frequently have multiple patients who need venous studies. Their solution is seldom efficient, and I could see every facility like this having the system so they can check their patients whenever they want.
