Abstract

The invention relates to a data processing device and method, electronic equipment and a storage medium, and the device comprises: a heart data obtaining unit, which is used for obtaining a first blood flow velocity at each moment in a first time period and a first blood vessel diameter at each moment in a second time period, wherein the first time period and the second time period have non-overlapping time periods; a corresponding relation determining unit, which is used for determining the corresponding relation between the first blood vessel diameter and the first blood flow velocity at each moment; and a blood flow determining unit, which is used for determining the first time period and the second time period of the blood flow by utilizing the first blood vessel diameter and the first blood flow velocity which have the corresponding relationship, wherein each of the first time period and the second time period at least comprises one cardiac cycle. According to the embodiment of the invention, the blood flow measurement accuracy can be improved.

Description

technical field [0001] The present disclosure relates to the field of data processing, and in particular, to a data processing method, device, electronic equipment, and storage medium. Background technique [0002] Blood flow is the volume of blood passing through the vertical cross-section of blood vessels per unit time, also known as volume rate. The calculation of clinical blood flow is generally obtained by measuring the average blood flow velocity and the cross-sectional area of ​​blood vessels, and then calculating through the flow formula. [0003] It is generally assumed that the cross-section of the blood vessel is circular, and a fixed value of diameter is obtained from an ultrasound image, and the cross-sectional area of ​​the blood vessel is calculated by using the fixed value of the diameter. However, because blood vessel pressure changes in real time and vessel walls are highly elastic, vessel diameter changes as the heart contracts and relaxes during the card...
