Improvement Study on Measuring Method of X-Ray Grid Characteristics

Authors attempted grid performance test by film methods than can be used easily on the hospital. And we investigated the utility of it comparing with the values measured by fluorescence meter recommended to be used ordinarily. The result was that, the characteristic values obtained by film methods was almost the same as those obtained by fluorescence meter methods. And besides plain film methods that can be applied simply showed small standard deviation. Therefore, we considered that it can be adopted easily on the labor that was not ready for special measuring apparatus like fluorescence meter.
