  • Patent number: 8795181
    Abstract: A system and method is provided for using dynamic ultrasonic imaging to analyze a subject's carpal tunnel and generate risk factors indicative of the health of the subject's subsynovial connective tissue and the subject's risk of developing carpal tunnel syndrome. The system and method uses speckle imaging techniques to track dynamic structures within the carpal tunnel and statistical analysis techniques to compare the properties of these dynamic structures of the subject to those of normal subjects and subjects having carpal tunnel syndrome.

  • Patent number: 8216148
    Abstract: This disclosure describes methods for detecting early stages of disease, in particular carpal tunnel syndrome, by using cooperative ultrasound techniques. In a particular embodiment, a grayscale ultrasonogram may be used to detect local anatomical features within the carpal tunnel by physically moving a tendon and identifying the corresponding feature on the ultrasonogram display device. A high-resolution color Doppler ultrasound device may then be used to interrogate features of anatomy surrounding the tendon for disease. In a particular embodiment, the color Doppler ultrasound device may be used to measure the velocities of the tendon and surrounding anatomy, in particular the sub-synovial connective tissue; the resultant data may be used to quantify certain anatomical anomalies, indicative or non-indicative of carpal tunnel syndrome.
