SYSTEM AND METHOD OF ULTRASOUND IMAGE PROCESSING

摘要

An ultrasound system includes an ultrasound transducer adapted to obtain a dynamic series of echo signals of a subject tissue at different deformation states, and an image processor for generating and displaying ultrasound images of the tissue. The processor is configured to generate dynamic images that correspond to the dynamic series of echo signals, identify a plurality of pixels within a region of interest (ROI) of a first of the generated images, evaluate local tissue mechanical behavior by tracking the displacement, deformation, and echo intensity of the identified plurality of pixels from the first image to subsequent images based on groups of pixels that correspond to each of the identified plurality of pixels, determine tissue functionality in the subject at the tracked pixel locations, and display the tissue functionality in dynamic images that corresponds to the tracked pixel locations.

主权项

1. A non-transitory computer readable storage medium having stored thereon a computer program comprising instructions which when executed by one or more computers cause the one or more computers to:
access a first image and a second image generated from a dynamic series of echo signals of a tissue acquired using an ultrasound transducer, wherein the second image represents the tissue at a different state of deformation than the first image; identify a location of a first plurality of pixels representing the tissue in the first image; assume a location of a second plurality of pixels representing the tissue in the second image; compare echo signals of the first plurality of pixels to echo signals of the second plurality of pixels; derive actual locations of the second plurality of pixels based on the comparison; calculate a deformation of the tissue between the first image and the second image from the derived actual locations of the second plurality of pixels; and output functionality information of the tissue based on the deformation.
