AI Technical Summary

Technical Problem

Existing ultrasound contrast imaging technology can only provide qualitative descriptions and cannot intuitively present the perfusion differences between the lesion area and the reference tissue in a larger range during the imaging process. In addition, quantitative analysis cannot accurately reflect the perfusion conditions of the entire process.

Method used

By obtaining the global time-intensity curve of the region of interest, the target angiography image is divided into the lesion region of interest, the necrosis region of interest and the reference tissue region. The lesion region of interest is then divided into multiple sub-regions, and the regional time-intensity curve of each sub-region is established to obtain the target parameters, and then perform mapping processing to generate a parametric image.

Benefits of technology

It achieves the intuitive presentation of perfusion differences in the region of interest within the imaging time, improves the accuracy and efficiency of parametric imaging, simplifies the operating process, and can better characterize the actual imaging situation.

Abstract

The application discloses a contrast parameter imaging method, an imaging device, electronic equipment and a computer readable storage medium. The scheme obtains a time point corresponding to a maximum slope in a rising stage based on a global time-intensity curve, takes a contrast image corresponding to a contrast image set as a target contrast image based on the time point, divides the target contrast image into a lesion area of interest, a necrosis area of interest and a reference tissue area, divides the lesion area of interest into a plurality of sub-areas with a size of one imaging pixel, directly takes the necrosis area of interest as a sub-area, establishes a region time-intensity curve based on signal intensity changing with time in each sub-area, further obtains a target parameter based on the region time-intensity curve, and generates an image representing the target parameter of each sub-area, realizes contrast parameter imaging, can intuitively present perfusion differences of a range of an area of interest in a contrast time, and can balance the calculation accuracy and efficiency of the target parameter.
