Perfusion flow phantom using a peristaltic pump flow source for multi-modality medical imaging

幻影是一种无生命的物体，通常用于鉴定医学成像系统。模体的使用能够实现医疗成像设备的客观质量保证和性能测试，并减少动物和/或患者实验的需要，这些实验与招募、昂贵的护理、电离辐射风险和可变生理相关。最近，越来越多的努力投入到跨成像模式类型的动态图像采集(即超越静态图像)的研究和开发中。动态成像的应用有望成为整个领域的标准，尽管一些小的技术问题仍在解决中。

Phantoms are inanimate objects commonly used to qualify medical imaging systems. The use of phantoms enables objective quality assurance and performance testing of medical imaging equipment, and reduces the need for animal and/or patient experiments, which are associated with concerns over recruitment, costly care, risk of ionizing radiation, and variable physiology. Recently, increasing effort has gone into the research and development of dynamic image acquisitions (i.e. moving beyond static images) across the spectrum of imaging modality types. Application of dynamic imaging is expected to become standard across the field, even though minor technical issues are still being solved.
