Monitoring the blood based on the short axis view.
Real-time computation of the blood flow.
Automatic system: no need for manual tuning.
Standard and low cost: software solution usable with any Color Flow Doppler machine
Reproducible: complete automation, no room for operator influence.
Polyvalent: adaptive to any ultrasound probe type (e.g. transesophageal)
Extensible to other image analysis functionalities (e.g. complex targeting).

Outline

An ongoing issue in vascular medicine is the measure of the blood flow. Catheterization remains the gold standard measurement method, although non-invasive techniques are an area of intense research. We hereby present an computational method for real-time measurement of the blood flow from color flow Doppler data, with a focus on simplicity and monitoring instead of diagnostics. We then analyze the performance of a proof-of-principle software implementation.

We provide here the Java code for the demonstrator of the blood flow measurement from the video of Color Doppler Flow. It is enough fast to run in real-time.
