The Design And Implementation Of Stress Echocardiography Test Offline Subsystem

With the development of cardiac ultrasound imaging techniques, stress echocardiography test(Stress Echo) is more applied in clinical. Stress echocardiography plays an increasingly important role in the non-invasive diagnosis of myocardial ischemia, and other heart disease diagnosis. Stress echocardiography test, ECG stress test and nuclear cardiac stress test common composition a modern cardiology diagnostic system. Compared with ECG stress test, Stress echocardiography test has more accurate in terms of detection of myocardial ischemia. Stress echocardiography test and nuclear cardiac stress test have similar capabilities in the cardiac diagnostic. But stress echocardiography test is cheaper than nuclear cardiac stress test.This paper is based on the clinical requirements and stress echocardiography in clinical usage, design and develop the ultrasound offline view system. The system based on Windows platform, using C++ language development. The system uses the SQLite database to store data, and uses the GUI Qt framework to implement user interaction. In this system, the display and event response of the irregular widget is realized by using the Qt control the drawn. Doctors to the section of the segment score. Use Q-T timetable calculate systolic and diastolic, a comparative analysis of the ultrasonic echocardiography can be performed before and after the stress. The doctor can obtain the ultrasonic inspection data on the personal computer, scan the echocardiography, analysis of cardiac wall motion and score for the segment. It output of the ultrasonic stress echo report, complete the work of the stress echocardiography test.Stress echocardiography test system can meet the basic requirements of the stress echocardiography test and provide strong support for the diagnosis of cardiac ultrasound. Design and implement ultrasound offline view system is a summary and refining of ultrasound clinical experience. It able to complete the requirement of clinical diagnostic ultrasound, and reduce a lot of working hours of the ultrasound machine, and have a high value for apply.
