Development and Application of a Quality Control Body Model for Ultrasonic Doppler Diagnostic Instrument
Objective:To develop a variety of ultrasonic Doppler diagnostic instrument quality control body model development,for medical equipment application quality and technical evaluation.At present,the quality control standard of ultrasonic Doppler diagnostic instrument in medical institutions is not perfect,the supervision is not in place,many equipment"with disease"operation,adverse events occur from time to time,strengthening the quality control is urgent.Based on the existing quality control means of ultrasonic Doppler diagnostic instrument,this paper will further study the development and application of ultrasonic Doppler diagnostic instrument quality control body model.Methods:According to the principle of ultrasonic Doppler imaging research and analysis of the merits of the existing die bodies,according to China national standard selected die body detection project,according to the standard adult normal blood vessels outside diameter and inner diameter size design of generic simulated blood vessels,making AGAR gel type body model,AGAR gel mould,internal wore two silicone tube,with a peristaltic pump drive,can control the flow velocity and direction,simulation of blood flow velocity change,blood flow state,simulation of blood flow direction recognition,as well as the depth of detection,under the ultrasonic verification of each indicator.Results:The quality control body model of ultrasonic Doppler diagnostic instrument was developed.By simulating human tissue and blood flow,and by controlling flow velocity,direction and depth,the probe of ultrasonic Doppler diagnostic instrument was detected,so as to verify the reliability,fast and accurate detection of the equipment and probe,and achieve the development goal.Conclusion:With the development of ultrasonic Doppler diagnostic instrument,ultrasound imaging technology is also improving,and ultrasound imaging as a data in medical diagnosis becomes more and more important.In color Doppler echocardiography use place,under the change of performance index in the process of decline in the quality also gradually exposed,combining with hospital colour to exceed in use process quality control body model,discusses ultrasonic Doppler in the diagnosis of image quality analysis,in order to better master the quality control method of color Doppler echocardiography,ensure that image quality.
