A new phantom is described which simulates the human cardiac anatomy for applications in ultrasound imaging, ultrasound Doppler, and color-flow Doppler imaging. The phantom consists of a polymer left ventricle which includes a prosthetic mitral and aortic valve and is connected to a mock circulatory loop. Aerated tap water serves as a blood simulating fluid and ultrasound contrast medium within the circulatory loop. The left ventricle is housed in a Lexan ultrasound visualization chamber which includes ultrasound viewing ports and acoustic absorbers. A piston pump connected to the visualization chamber by a single port pumps degassed water within the chamber which in turn pumps the left ventricle. Real-time ultrasound images and Doppler studies measure flow patterns through the valves and within the left ventricle.
本文描述了一种新型体模,它模拟人体心脏解剖结构,用于超声成像、超声多普勒和彩色血流多普勒成像。该体模由一个聚合物左心室组成,其中包括一个人工二尖瓣和主动脉瓣,并连接到一个模拟循环回路。曝气自来水用作循环回路中的血液模拟流体和超声造影剂。左心室置于一个聚碳酸酯超声可视化腔室中,该腔室包括超声观察端口和吸声体。通过单个端口连接到可视化腔室的活塞泵在腔室内泵送脱气水,进而泵送左心室。实时超声图像和多普勒研究测量通过瓣膜和左心室内的血流模式。
