Abstract

The purpose of this study is to evaluate the tube current profile of Siemens 128 slice CT scanner with tube current modulation (TCM) technique using the Borobudur phantom. Borobudur phantom was made from acrylic which has four different diameters of 8, 16, 24, and 32 cm. It was filled with distilled water. The phantom was scanned using a Siemens Somatom 128 slice CT Scanner. The CT scanner took a topogram image first to estimate the attenuation level of each diameter of the phantom. The phantom was scanned using tube voltage and quality reference variations. After the axial images of the phantom were obtained, the tube current information was extracted from digital imaging and communications in medicine (DICOM) header in each dataset using through IndoQCT software. It is found that as the phantom diameter increases, the tube current also increases. For variation of quality reference, the increasing value of quality reference will increase the tube current value. The results show that the tube current profile in the tube voltage variation shows insignificant changes with a statistical test p-value of 0.752. From this study, we conclude that TCM can be evaluated using Borobudur phantom and IndoQCT software.
