CT Simulator For Bone Mineral Analysis 004


Change in trabecular bone mineral content is an early indicator  of change in metabolic function. CT, with its superior contrast discrimination, is a major tool in the evaluation of trabecular bone in the central skeleton. All CT scanners require a standard of reference to properly perform quantitative tissue analysis.


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.
