It has been studied on the scanogram of the CT Scanner calibration with Phantom head to find out its value of the CT number, in the Radiodiagnostik Instalation in the RSUP dr Kariadi Semarang. The CT number is a value of the Inier attenuation coefrisien of the bodies tissue on a scanogram. In the ten different oases of study, the researcher scanned ten different images to evaluate ten different CT scanner's sistem problems, then she counducted CT Scanner calibration with Phantom and finally she scanned the calibrated CT scanner. Scennograf of head has been done in this study to evaluated the value of the CT number for different tissues. Key word : Calibration, CT number, CT Scanner
