四维（4D）扩展心脏-躯干（XCAT）系列的幻影是为了提供准确的人体解剖和生理的计算机模型而开发的。XCAT系列包含了从新生儿到成人的大量不同年龄的幻影，每个都包括心脏和呼吸运动的参数化模型。XCAT的设计具有很大的灵活性，可以模拟任何数量的身体尺寸、不同的解剖结构、心脏或呼吸运动或模式、患者的位置和方向以及空间分辨率。因此，XCAT幻影在生物医学成像研究中得到了广泛的应用。在那里，他们可以提供一个虚拟的病人基础，从这个基础上定量评估和改进成像仪器、数据采集、技术以及图像重建和处理方法，从而提高图像质量和更准确的临床诊断。这些幽灵在辐射剂量测定、放射治疗、医疗设备设计，甚至安全和国防工业中也有很大的用途。这篇综述文章重点介绍了XCAT幻影在生物医学成像和其他领域中的应用。从这些例子中，我们说明了计算机模拟和计算机模拟在研究界所起的日益重要的作用。
The four dimensional (4D) eXtended CArdiac-Torso (XCAT) series of phantoms was developed to provide accurate computerized models of the human anatomy and physiology. The XCAT series encompasses a vast population of phantoms of varying ages from newborn to adult, each including parameterized models for the cardiac and respiratory motions. With great flexibility in the XCAT’s design, any number of body sizes, different anatomies, cardiac or respiratory motions or patterns, patient positions and orientations, and spatial resolutions can be simulated. As such, the XCAT phantoms are gaining a wide use in biomedical imaging research. There they can provide a virtual patient base from which to quantitatively evaluate and improve imaging instrumentation, data acquisition, techniques and image reconstruction and processing methods which can lead to improved image quality and more accurate clinical diagnoses. The phantoms have also found great use in radiation dosimetry, radiation therapy, medical device design, and even the security and defense industry. This review paper highlights some specific areas in which the XCAT phantoms have found use within biomedical imaging and other fields. From these examples, we illustrate the increasingly important role that computerized phantoms and computer simulation are playing in the research community.
