The Effect of Kilovoltage and Milliampere-Second Parameters on CT Number: Study Phantom Quality Control CT Scan

---

CT number is one of the indicators in determining the diagnosis of disease, so it is necessary to ensure the level
of accuracy. The aim is to determine the parameters of kilovoltage and tube current to the CT value. Descriptive
quantitative analytic research method with previously tested linearity and the suitability of the CT number.
Furthermore, the variation of kilovoltage: 80 kVp, 100 kVp, 140 kVp and the tube current value is 192 mAs.
After that, the tube current variation was continued: 80 mAs, 100 mAs, 140mAs and the voltage value was 120
kVp. Phantom image results were analysed using radiant viewer software with a region of interest (ROI) size
of 5 mm. Then analyse the correlation coefficient to determine the degree of relationship between the
kilovoltage and milliampere-second parameters to the CT number. The results of the linearity test and the
suitability of the CT number value were within the tolerance limit. For variations in kilovoltage to CT number,
the correlation coefficient values are water R2=0.09, fat R2=1, soft tissue R2=0.9, bone R2=0.7. As for the
milliampere-second variation of the CT number, the correlation coefficient values are: water R2=0.7, fat R2=0.8,
soft tissue R2=1, bone R2=0.7
