Title:
ESTIMATING STRAIN ON TISSUE USING 4D ULTRASOUND CATHETER
Document Type and Number:
Japanese Patent JP2023004945
Kind Code:
A
Abstract:
To provide a medical system.SOLUTION: The medical system includes an ultrasound probe configured for insertion into an organ of a body, and a processor. The probe includes a two-dimensional (2D) ultrasound transducer array, and a sensor configured to output signals indicative of a position, direction and orientation of the 2D ultrasound transducer array inside the organ. The processor is configured to (a) use the signals output by the sensor to register multiple ultrasound images of a tissue region, acquired over a given time duration by the 2D ultrasound transducer array, with one another, (b) estimate, based on the ultrasound images acquired over the given time duration, three-dimensional displacements as a function of time for one or more locations in the tissue region, (c) estimate respective mechanical strains of the one or more locations in the tissue region, based on the three-dimensional displacements, and (d) present a time-dependent rendering of the mechanical strains to a user.SELECTED DRAWING: Figure 1
