Embodiment Construction

[0038] figure 1 Shown is an apparatus 100 integrated in an apparatus 200 created and configured to measure liver elasticity to calculate a score reflecting the state of liver disease.

[0039] In this non-limiting embodiment, the device 200 includes an elastogram probe 201 equipped with an ultrasound transducer 202 constructed and configured to transmit and receive ultrasound waves. In this mode of implementation, the elastogram detector 201 also includes means for generating shear waves in the liver tissue. The device may be an electric actuator 203 created and configured to generate low frequency waves. Thus, device 200 was created and configured to measure physical parameters, eg, parameters related to inflammation and / or fibrosis and parameters related to steatosis.

[0040]As an example, a parameter related to fibrosis may be liver elasticity. This measure of elasticity constitutes a marker of the pathological state of the liver tissue.

[0041] The steatosis-related ...

Abstract

The invention particularly relates to a device (100) for calculating a score (205) reflecting a state of liver damage, said calculating device (100) being designed to calculate a score (205) using the following physical parameters: a parameter corresponding to inflammation and / or fibrosis; and a parameter corresponding to steatosis.

Description

technical field [0001] The invention relates to a non-invasive detection device for liver lesions using ultrasonic waves and shear waves. The device can be used in humans and livestock and, for example, to detect liver lesions of the fatty liver type caused by alcoholism (also known by the English acronym ASH (Alcoholic SteatoHepatitis)) or liver lesions caused by non-alcoholic intoxication (The English prefix NASH (Non Alcoholic Steato Hepatitis) is also known). The present invention also relates to a score reflecting liver lesions. Background technique [0002] Traditionally, chronic diseases of liver tissue produce liver lesions such as fibrosis. Fibrosis is the healing process of fibers in the liver tissue caused by inflammation. Initially asymptomatic fibrosis may progress to cirrhosis. The elasticity of liver tissue constitutes a marker of fibrosis. In order to measure and quantify the elasticity of liver tissue, it is known to use pulse elastography, as described...
