Problems solved by technology

However, slow low-volume blood flow, for example in capillaries, may not be visualized by conventional Doppler methods, and thus Doppler ultrasound may not be able to visualize different vascular structures (e.g., different sized vessels) in the region of interest. Blood vessel)
Also, for example, Doppler ultrasound cannot be used to visualize organ structures to visualize blood flow distribution and perfusion in regions of interest

Abstract

A method and computer readable storage medium for contrast enhanced ultrasound quantization imaging. One of the methods comprises: for each position in a region of interest, acquiring a time-varying ultrasonic signal associated with the region of interest within a time period; for each location, a processed time-varying ultrasound signal is determined based at least on the acquired time-varying ultrasound signal, where: a portion where a local increase exceeds a threshold is mapped, and a portion where a local increase does not exceed the threshold is flattened; an image sequence of the region of interest is generated based at least on the processed time-varying ultrasound signals at each location, where the generated image sequence displays signal variations of the processed time-varying ultrasound signals in one or more structures in the region of interest to represent the one or more structures.

Description

technical field [0001] The present application relates generally to contrast-enhanced ultrasound quantitative imaging, and more particularly to methods and systems for visualizing the direction and distribution of blood flow in vascular structures. Background technique [0002] Ultrasound imaging is a non-invasive medical testing technique that examines soft tissues in the body, such as blood vessels, to reveal structural details of internal tissues and fluid flow. Many ultrasound imaging systems utilize injectable ultrasound contrast agents to obtain high-contrast images, which are desirable for visualizing blood flow in internal organ structures. For example, images of the direction and distribution of blood flow often aid doctors in diagnosis and treatment. [0003] Doppler ultrasound is an imaging test that shows blood flowing through blood vessels and is commonly used to detect and image fluid flow in the body, such as blood flow. In Doppler ultrasound, the frequency ...
