영문 초록

This study was found out change factors of dose efficiency in multi- detector CT. The dose efficiency was analyzed by change of technical scan parameter such as kVp, mA, pitch, SFOV, beam collimation with 8 & 16 channels CT. The results obtained were as follows; 1. Dose efficiency was higher 20 mm beam collimation than 10 mm beam collimation in all devices. 2. Dose efficiency was higher at small focal spot than large focal spot in all devices. 3. There was no change of dose efficiency about change of pitch in all devices. 4. There was no change of dose efficiency about change of SFOV in all devices. 5. The 16 channels MDCT was higher dose efficiency than 8 channels MDCT.
