AI Technical Summary

Technical Problem

Existing ultrasound imaging techniques are difficult to accurately diagnose heart failure with preserved ejection fraction (HFpEF), especially due to the high misdiagnosis rate caused by inaccurate measurement of myocardial stiffness and operator dependence.

Method used

By using a semi-automated ultrasound imaging system, high-quality image frames are automatically selected and myocardial propagation velocity is calculated using image quality scoring and myocardial propagation velocity calculation, and reports are generated to improve diagnostic accuracy.

Benefits of technology

It improves the diagnostic accuracy of HFpEF and the standardization of myocardial stiffness measurement, reduces inter-operator and intra-operator measurement errors, and enhances the reliability and reproducibility of measurements.

Abstract

An ultrasound imaging system can analyze the quality of images of a cardiac cycle before analyzing m-mode images associated with the images. In some examples, a user determines a number of cardiac cycles acquired by the ultrasound imaging system. In some examples, the ultrasound imaging system can detect a septum in the ultrasound images and automatically select a line through the septum for which to generate m-mode images. The ultrasound imaging system can analyze the m-mode images to determine myocardial propagation velocity measurements. In some examples, a report can be provided to the user. In some examples, outlier velocity measurements can be removed from the report.
