Abstract

To provide lab scale in vitro phantom solutions for cardiac MR (CMR) studies that can be used for imaging structure and function as well as calorimetric measurements. The phantoms were purposed to accept user inputs such as beats per minute (BPM) and flow rate. We developed two generations of phantoms. The first phantom was developed using poly vinyl alcohol driven by a mechanical setup. The second was a 3D-printed phantom controlled through a user interface (UI) and a peristaltic pump. These phantoms were scanned for the characteristics mentioned above, which were qualitatively and quantitatively assessed through postprocessing of CMR images and compared with in vivo data.

成本效益高，集成体外模型心脏MRI。

为心脏MR (CMR)研究提供实验室规模的体外模型解决方案，可用于成像结构和功能以及量热测量。这些幻影被用来接受用户输入，比如每分钟心跳数(BPM)和流速。我们开发了两代幽灵。第一个幻影是用机械装置驱动的聚乙烯醇开发的。第二个是通过用户界面(UI)和蠕动泵控制的3d打印幻影。扫描这些幻影以获得上述特征，通过CMR图像的后处理对这些特征进行定性和定量评估，并与体内数据进行比较。

期刊介绍： Biomedical engineering has been characterized as the application of concepts drawn from engineering, computing, communications, mathematics, and the physical sciences to scientific and applied problems in the field of medicine and biology. Concepts and methodologies in biomedical engineering extend throughout the medical and biological sciences. This journal attempts to critically review a wide range of research and applied activities in the field. More often than not, topics chosen for inclusion are concerned with research and practice issues of current interest. Experts writing each review bring together current knowledge and historical information that has led to the current state-of-the-art.
