STUDI UNIFORMITAS DOSIS RADIASI CT SCAN PADA FANTOM KEPALA YANG TERLETAK PADA SANDARAN KEPALA
ABSTRACT: The research on the
impact of tube current and tube
voltage on uniformity of the point dose
in the head phantom was placed on the table, had been conducted. The research
was carried out on the CT Scan machine, Siemens Somatom Emotion 6. The detector
used was CT dose profiler and Piranha Electrometer 556. The phantom was head
phantom with PMAA material with diameter 16 cm and length 15 cm. The
measurement of point dose carried out by using axial mode. The measurement
conducted in five points inside the head phantom. In this research, the tube
current and tube voltage were varied. The results show that the point dose on
the head phantom was placed on the table is non-uniform. At the bottom of the
phantom, the dose is lower to below 50% than at the top of the phantom.
