摘要：A new phantom for bone salt determination consists of a calcium phosphate cpd. as a bone-salt-equivalent substance dispersed in a high molecular cpd. The high mol. cpd. is pref. a thermoplastic resin or a water- or organic-solvent-soluble high molecular substance. In the prepn. of the phantom, a fluid prepolymer of the high molecular cpd. is dispersed in a calcium phosphate cpd. and allowed to polymerise. Alternatively, the calcium phosphate cpd. is dispersed in a molten thermoplastic resin and cooled to solidify, or a calcium phosphate cpd. is dispersed in an aq. or organic solvent soln. of a high molecular cpd., and the solvent removed to solidify. The high molecular cpd. is pref. one of polyurethane, polystyrene, acryl resin, polyethylene, polypropylene, nylon, polyvinyl alcohol, vinyl acetate, and epoxy resins. The calcium phosphate cpd. is pref. one or a mixt. of hydroxy-apatite, tricalcium phosphate, and tetracalcium phosphate.
