Ultrasonic parameter measurement method and ultrasonic parameter measurement system

Abstract

According to the ultrasonic parameter measuring method and the ultrasonic parameter measuring system, the area of a left lung area and / or the area of a right lung area and the head girth are determined respectively based on the obtained four-cavity heart standard section and the thalamus level standard section of a target fetus in the end of diastole, and therefore the lung-head ratio is determined; under the condition that a lump exists in the lung, based on the obtained lung lump area and the thalamus level standard cross section of the target fetus, the size and the head girth of the lung lump area are determined respectively, and therefore the lung-head ratio is determined; the two measurement methods comprise a full-automatic mode and a semi-automatic mode in the whole measurement process, and compared with manual measurement by a user in the prior art, the working efficiency and the measurement accuracy are improved.

Description

technical field [0001] The present application relates to the technical field of ultrasonic measurement, and more particularly to an ultrasonic parameter measurement method and an ultrasonic parameter measurement system. Background technique [0002] Ultrasonography has been widely used in clinical examination due to its advantages of safety, convenience, non-radiation, and low cost, and has become one of the main auxiliary means for doctors to diagnose diseases. Among the many examination items of ultrasound, the examination of fetal lung-to-head ratio is an important examination item. By measuring the lung-to-head ratio, it helps to screen whether the fetus has isolated lung, pulmonary cystadenomatous, and pulmonary diaphragmatic hernia and other diseases. The assessment of fetal growth and development is crucial. [0003] For the calculation of fetal lung-to-head ratio, it is necessary to first locate the four-chamber view and thalamic view of the fetus at the end of dia...

Problems solved by technology

[0003] For the calculation of fetal lung-head ratio, it is necessary to first locate the four-chamber view of the fetus at the end of diastole and the thalamus view, and then measure the lung area and head circumference based on the corresponding views. If there is a mass in the lung, it is also necessary to measure the lung mass. Manually tracing the lungs (or mass) and the brain not only requires certain clinical experience and knowledge, but also is very time-consuming, affects the doctor's work efficiency, and the assessment is inaccurate
