Advances in medical technology to evaluate the variety and frequency of the diagnostictest to learn the change of the noise value and the SNR according to the change in the tube voltageas a target in the MDCT trend to increase throughout the world for the high image acquisition andappropriate patient dose. This study in both the scan time, slice thickness, kernel value of Sʼs andthe same equipment Somatom Definition Flash Tube voltage 80, 100, 120, is changed to 140 kVp tomeasure the noise and SNR. Noise and SNR measurement is measured 10 times for each condition by setting the ROI in Clibration QC Phantom of the same size are shown as mean. Change in thenoise in the first Care Dose 4D decreased 60.8% increase relative to 80 kVp to 100 kVp to, decreased46.3% increase in 120 kVp, increasing to 39.8% and decreased to 140 kVp. And mA Fix (200 mA)decreased 63.1% increase in the 100 kVp based 80 kVp, decreased 48.7% increase in 120 kVp,decreased to 41.7% increase in when 140 kVp. First, the change in SNR Care Dose 4D decreasedby - 100% increase in 100 kVp based 80 kVp, 120 kVp to increase during - 366.7% decrease,decreased to - 433.3% increase in when 140 kVp and mA fix (200 mA) The 83.3% increase relativeto the increase in 100 kVp, 80 kVp, increase 120 kVp increased by 250%, increased from 383.3%increase in when 140 kVp. In this study with an increase in the tube voltage was found with theNoise SNR is reduced, the noise proper to valuable diagnostic image acquisition, with the tube voltagevalue and the optimum SNR is believed to minimize patient dose.
