Fetal imaging system and method

Abstract

An ultrasound fetal imaging system uses an acceleration sensor (16) for generating an acceleration signal relating to movement of the ultrasound transducer (10). A user is guided in how or where to move the ultrasound transducer based on the results of image processing of the ultrasound images. The user can thus be guided to move the transducer in a certain direction so as to achieve a complete scan of a fetus in a shortest possible time. This limits exposure of the expectant mother to the ultrasound energy. The fetal image obtained may be used to determine a fetal weight, for example using regression analysis based on some of the parameters derived from the obtained image.

Description

technical field [0001] The present invention relates to fetal imaging systems and methods. Background technique [0002] One purpose of fetal imaging is to provide an estimate of fetal weight. [0003] Accurate estimation of fetal weight plays an important role in routine antenatal care and detection of fetal growth abnormalities. [0004] In current obstetric practice, the two main approaches to predict birth weight are the first clinical estimation based on abdominal palpation and base height measurements of fetal body parts, and the second based ultrasound measurements of skeletal fetal parts, which are then plugged into the regression equation to derive estimated fetal weight. Ultrasound estimation is the most accurate method of fetal weight estimation compared to other methods. [0005] Studies have been conducted to compare the accuracy of methods for estimating birth weight before birth, and the accuracy of ultrasound estimates was found to be superior to clinical ...
