用于骨礦物分析的CIRS Model 004 CT模擬器旨在通過使用基本上等同于人的材料，通過模擬平均患者的形狀和密度的解剖結構來考慮影響椎體密度測量的所有已知來源關于X射線相互作用的組織，包括椎體組成中的年齡相關變化。

系統的設計允許將所有誤差源減少到可接受的限度內。仔細和精確的制造和質量控制確保所有幻影是相同的，以創建適用于所有掃描儀的一般和統一的標準。操作的基本原理是充分模擬患者的解剖結構，然后以相同的技術因素連續掃描病人和體模。

CIRS 004模體可與所有CT掃描儀一起使用，并允許對病人進行連續檢查，無論掃描儀使用如何。數據解釋和分析可以“離線”執行，以消除不必要的掃描時間。

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.
