    • An apparatus for calibrating an x-ray computed tomography device has a plurality of objects formed from a material that is visible to x-rays, and a base at least in part fixedly supporting the plurality of objects so that each of the plurality of objects contacts at least one of the other objects. Each one of the plurality of objects: 1) is configured to receive x-rays without changing shape, 2) has substantially the same shape and size as the other objects, 3) has an attenuation value to x-rays (“object attenuation value”), and 4) is symmetrically shaped relative to its center point. Like the objects, the base also has an attenuation value to x-rays (the “base attenuation value”). The object attenuation value is greater than the base attenuation . Each of the plurality of objects is kinematically locked in place on the base.
    • 用于校准X射线计算机断层摄影装置的装置具有由X射线可见的材料形成的多个物体,以及至少部分地固定地支撑多个物体的基部,使得多个物体中的每一个接触 至少一个其他对象。 多个对象中的每一个:1)被配置为接收x射线而不改变形状,2)具有与其他对象大致相同的形状和尺寸,3)具有对x射线的衰减值(“对象衰减值 “)和4)相对于其中心点对称成形。 像物体一样,基座也具有x射线的衰减值(“基极衰减值”)。 物体衰减值大于基极衰减值。 多个对象中的每一个被运动地锁定在基座上的适当位置。

    • An imaging method positions a heterogeneous object within a fixture having a chamber. The fixture also has a valve for receiving a gas and normally sealing the chamber. Thus, the object is within the chamber. Next the method positions the fixture within an active region of a CT machine, fluidly connects a gas line to the valve, and injects an inert gas into the chamber through the gas line and the valve. The inert gas may include one or more of the xenon, argon, and krypton. The method then increases the pressure within the sealed chamber to increase the density of the gas within the chamber, and directs x-ray energy toward the active region of the CT machine to produce a plurality of two-dimensional images of the object and the pressurized gas. Finally, the method generates a three-dimensional representation of the object from the plurality of images.
    • 成像方法将异质物体定位在具有腔室的固定装置内。 夹具还具有用于接收气体并且通常密封腔室的阀。 因此,物体在室内。 接下来,该方法将夹具定位在CT机器的有效区域内,将气体管线流体连接到阀门,并通过气体管线和阀门将惰性气体注入腔室。 惰性气体可以包括一种或多种氙,氩和氪。 该方法然后增加密封室内的压力以增加腔室内气体的密度,并且将X射线能量引向CT机的有源区域以产生物体的多个二维图像和加压 加油站。 最后,该方法从多个图像生成对象的三维表示。
