Preliminary study on mobile platform-oriented echocardiogram data visualization for the evaluation of left ventricular diastolic function / 中华超声影像学杂志

ABSTRACT

Objective To research and develop the mobile platform-oriented echocardiogram data visualization technology for the evaluation of left ventricular diastolic function,and investigate its application value.Methods First,diagnostic algorithms for the evaluation of left ventricular diastolic function (based on recommendations from ASE & EAE guidelines) were programmed into a mobile application software package,using Adobe Flex builder 4.0 as a basic tool for data visualization.Second,the program was installed in the Apple iPad4 tablet computer,then debugged and improved according to feedback information from practical applications.Results The echocardiogram data visualization for the estimation of left ventricular filling pressures in patients with depressed ejection fraction(EF) or normal EF and grading diastolic function can be implemented in mobile platform device,and simultaneously with emergency bedside echocardiography.The evaluation process can be visually presented by using the graphics to show the algorithm framework,the animation to express the analysis step,the axis to indicate the direction of information,and the color to differentiate the degree of the diastolic dysfunction.Conclusions The mobile platform-oriented echocardiogram data visualization technology makes the evaluation of left ventricular diastolic function more convenient,efficient and fast,and shows its potential to become an important adjunct to evaluation of cardiac function in the context of mobile health.
