摘要:
 论述了动态心脏体模作为计算机断层扫描(CT)设备心脏成像质量评价与质量保证工具的重要性;介绍了当前几类动态心脏体模在心脏CT成像质量控制中的应用进展,包括运动型、功能型和仿真型动态心脏体模。分析了现有动态心脏体模在解剖结构、组织材料和运动特性的不足,并提出利用等效材料制作四腔室心脏体模和基于容积-时间曲线控制模拟心脏全周期运动的可行性,以探究研制一种“结构仿生、运动仿真”动态心脏体模的可行性,从而为建立心脏CT成像质量定量评价标准提供理论依据和技术支撑。
Abstract:
 The current dynamic heart phantom is classified as moving gated, functional and simulation phantoms. Herein the significance of dynamic heart phantom applied for the quality evaluation and quality assurance of cardiac computed tomography (CT) imaging is briefly discussed, and its developments in the quality control of cardiac CT imaging are introduced. The analysis revealed that the existing dynamic heart phantoms have limitations in anatomical structure bionic design, tissue equivalent material and movement characteristics simulation. Therefore, the feasibilities of using equivalent material to establish a four-chamber heart phantom and simulating motions in the whole cardiac cycle based on volume-time curve are expounded. Furthermore, the possibilities of a dynamic heart phantom of "structure bionic design and motion simulation" are investigated. This study provides theoretical basis and technical support for the establishment of standards for quantitatively evaluating the cardiac CT imaging quality.
