Pulsatile Flow Phantoms for Quality Control of Doppler Ultrasound Imaging

摘要

In this work it is proposed the development of phantoms to allow de quality control of ultrasound equipments functioning on the Doppler mode with national technology and accessible cost. The device consists of a hydraulic circuit with a peristaltic pump, mixture simulating human tissue, tubes simulating arteries and blood-mimicking fluid. The peristaltic digital pump made the simulation of cardiac beats possible, operating at flow rates of 45 to 150 ml/min and pulse rates of 60 to 200 beats/min. The blood-mimicking fluid simulated the human red cells as particles of PVC powder with approximately 64 |μm diameter, distilled water, glycerin, detergent and dextran.
