Deep Venous Thrombosis Screening System Using Numerical Measures

An experimental system and interface that indicate the likelihood of deep venous thrombosis using objective numerical measures was developed, based on the conventional compression ultrasound examination. A sensorized ultrasound probe is used to acquire force, location and image data to assess a vessel segment for compression. Ultrasound image data is segmented using a modified Star-Kalman algorithm. A user interface displays the results using a 3-D representation. A tissue phantom was developed for testing and validation. Initial results with this phantom and healthy volunteers are presented.
