用于骨矿物分析的CIRS Model 004 CT模拟器旨在通过使用基本上等同于人的材料，通过模拟平均患者的形状和密度的解剖结构来考虑影响椎体密度测量的所有已知来源关于X射线相互作用的组织，包括椎体组成中的年龄相关变化。

系统的设计允许将所有误差源减少到可接受的限度内。仔细和精确的制造和质量控制确保所有幻影是相同的，以创建适用于所有扫描仪的一般和统一的标准。操作的基本原理是充分模拟患者的解剖结构，然后以相同的技术因素连续扫描病人和体模。

CIRS 004模体可与所有CT扫描仪一起使用，并允许对病人进行连续检查，无论扫描仪使用如何。数据解释和分析可以“离线”执行，以消除不必要的扫描时间。

The CIRS Model 004 CT Simulator for Bone Mineral Analysis is designed to take into account all the known sources of variance affecting the measurement of density in the vertebral area by simulating the average patient’s anatomy in terms of shape and density by using materials essentially equivalent to human tissues as far as X-ray interactions are concerned, including age-related variations in vertebral composition.

The design of the system permits reduction of all sources of error within acceptable limits. Careful and precise manufacturing and quality controls insure that all phantoms are identical in order to create a general and uniform standard applicable to all scanners. The basic principle of operation is to sufficiently simulate the patient’s anatomy, and then to scan the patient and the phantom in succession with identical technical factors.

The Model 004 works with all CT Scanners and permits serial examinations of the patient irrespective of scanner use. Data interpretation and analysis can be performed “off line” to eliminate unnecessary scanner time.
