dc.description.abstract	Noise measurements have been carried out with changes in thick slices CT Scan image by selecting the ROI on a water phantom objects. The method used in the measurement of noise values ranging from 1 mm, 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, and 10 mm and eksposi factor of 100 kV and 500 mAs. The results obtained are 6.32 HU; 5:14 HU; 3.86 HU; HU 3:48; HU 3:14; 2.94 HU; 2.78 HU; 2.52 HU; HU HU 2:44 and 2:38. The thicker slices diminishing the noise then the resulting CT images were good	en_US
