Abstract :本研究は、小児股関節の低線量CR撮影におけるシステム感度のS値と表面線量簡易換算式(NDD法)によって算出した入射皮膚表面線量(以後、皮膚線量)の関係から、最小2乗法を用いて被曝線量の簡易推定式を求めたので報告する。
In order to easily estimate exposure dose in facilities without measuring instruments such as a dosimeter, the relationship between a S value (an index of sensitivity) and exposure dose (incidence skin surface dose) derived from a non-dosimeter dosimetry (NDD) method, was investigated. The equation which estimates the exposure dose from the S value was determined from the relationship among the hip thickness, the exposure dose obtained by the NDD method and the S value. The coefficient of determination of 0.83 showed relatively good fitness of this equation. This study demonstrates that a child exposure dose in low-dose radiography of hip joints using a computed radiography (CR) system can be easily estimated from the S value.
