Abstract 胃Ⅹ線検査に造影剤として用いられる硫酸バリウム懸濁液の濃度を,簡便に,客観的に決定する目的で,歯科用アルギン酸塩印象材を用いて,コインの図柄を写しとったファントムを制作した。これを使って二種類の硫酸バリウム製剤の適正濃度(PD)を調べた結果,BARITOP PとBARICON MEALを単体,若くは混合した場合には,おおよそ,PD(W/V%)=0.75C+165(ただし,CはBARICON MEALの混合比(%))となった。また,BARICON MEALはコントラストが高く,精密検査に有利だと考えられ,BARITOP PとBARICON MEALを混合すると濃度の許容範囲が広がるため,通常の検査に都合がよいと考えられた。更に,このファントムは簡便に作成することができ,しかも,硫酸バリウム懸濁 液との親和性も良いことから,硫酸バリウム製剤やⅩ線TV装置の評価,増感紙・フィルム系の評価等にも応用できると考えられた。
Abstract Alternative A phantom copied designs of coins was created with alginate dental impression material to establish a objective, simple and easy method for deciding density of barium sulfate suspensions which are used for stomach X-ray examination as contrast media. As a result of examining proper density (PD) of two kind of barium preparations with this phantom, in case of BARITOP P and BARICON MEAL, PD were almost shown by the next equation : PD(W/V%)=0.75C+165(C meant content of BARICON MEAL (%)). As BARICON MEAL resulted in hight contrast, it was thought to be suitable for a close examination. Mixture of BARITOP P and BARICON MEAL was thought to be suited to a routine examination becouse of wide permissible level of density. This phantom would be able to apply to the test of balium preparations, X-ray TV systems, screen/film systems and so on.
