<P>PROBLEM TO BE SOLVED: To provide an x-ray calibration device that models an abdomen of a patient. <P>SOLUTION: The x-ray calibration device 300 includes a core 302 including a first material with a first x-ray attenuation coefficient. The core 302 defines a cavity 306 that is configured to receive a plug of a different x-ray attenuation coefficient in order to alter the x-ray attenuation coefficient of the x-ray calibration device 300. The x-ray calibration device 300 also includes an outer layer 304 at least partially surrounding the core 302. The outer layer 304 includes a second material with a second x-ray attenuation coefficient, where the second x-ray attenuation coefficient is lower than the first x-ray attenuation coefficient. <P>COPYRIGHT: (C)2013,JPO&INPIT |
