Understanding the Contrast Mechanism in Rotation Elastogram: A Parametric Study.

Ultrasound elastography has been found to be useful in different clinical applications. For example, in breast imaging, axial strain elastography provides information related to tissue stiffness, which is used to characterize breast lesions as either benign or malignant. In addition, these lesions also differ in their bonding properties.

ARTSENS® orientation navigation system: A study towards faster arterial stiffness measurements.

ARTSENS® (ARTerial Stiffness Evaluation for Non-invasive Screening) is a technology for image-free evaluation of carotid artery stiffness with intelligent real time ultrasound signal processing algorithms for arterial wall identification and tracking. However, the influence of the ultrasound probe orientation on the clarity of the artery wall echoes makes measurement a challenge for inexperienced operators. We present an orientation navigation system (ONS), which performs real time tracking of the probe orientation and gives feedback to the user to help take faster readings with more ease for novice ARTSENS® operators.
