本研究ではインクカートリッジに14C標識化合物を添加混合し，写真用紙に印字したイメージングプレート（IP）用面線源及び検量線を作製し，その応用を検討した。本面線源とIPを密着露光してBAS-5000計測から，本面線源の面均一性及び直線性が確認された。またアルミ箔を用いた密度検量線作製用試料とラット凍結乾燥切片との密着露光による骨密度定量の可能性を認めた。
We prepared a surface source for imaging plates (IPs) by adding a 14C-labeled compound into ink cartridges and subsequent printing on photographic paper. The BAS-5000 measurement of the IPs confirmed that the surface source showed uniform distribution of radioactivity. The radioactivity counts and photostimulated luminescence levels were well correlated with the transmission levels of the printer. In addition, the present study also suggested the application of the surface source to bone density quantification of experimental animals.
Key words: surface source; imaging plate; radioluminography; carbon-14; uniformity. bone density
