Embodiment Construction

[0025] In the following description, non-limiting exemplary embodiments of the invention will be described in more detail. In this example, the invention is applied to breast elastography, where the obtained elastogram can help differentiate between benign and malignant tumors. It should be noted that the invention is not limited to this application, but that the invention can also be applied to echocardiography, where real-time inspection of TDI information will evaluate the acquired values, and the offline speckle tracking method will also lead to a good understanding of relevant clinical parameters. calculate.

[0026] figure 1 An ultrasound sensor probe, also referred to as a transducer 101, is shown placed on a patient's chest for obtaining ultrasound signals from the patient's tissue. An ultrasonic transducer is a device that converts energy into ultrasound or sound waves above the normal range of human hearing. The transducer 101 is connected to a processing unit 103...

Abstract

Elasticity variation within biological tissue is often correlated with its pathology. Variation of elasticity can be assessed by specific ultrasound acquisition sequences during which pressure is applied. The tissue motion and deformation during those sequences is correlated to the tissue stiffness. The present invention describes a hybrid method that combines a real-time monitoring mode during acquisition and a non-real-time fine analysis after acquisition. This method allows early identification and fair assessment of pathology from elastographic analysis to obtain the best possible result for elastography assessment.

Description

technical field [0001] The invention relates to a method for obtaining tissue strain data. Such strain data can be obtained using an ultrasound probe, also called a transducer. The invention also relates to a corresponding computer program product and measuring device. Background technique [0002] Elastic changes within biological tissues are often associated with their pathology. Changes in elasticity can be assessed by a specific ultrasound acquisition sequence in which pressure is applied during its acquisition. Tissue motion and deformation during those sequences correlates with tissue stiffness. For example, breast cancer tumors exhibit greater stiffness than surrounding tissue. [0003] Elastogram analysis involves the measurement of elasticity of biological tissue when it is subjected to external constraints; such as compression from an ultrasound probe. This compression is generated by the operator, so it is virtually impossible to control the speed and magnitu...
