THESIS, 2023 FERDI WIJAYANTO ANALYSIS OF CT NUMBER AND NOISE VALUES BEFORE AND AFTER CALIBRATION AS QUALITY CONTROL PROGRAM OF CT SCAN MACHINE 5 Chapters + 48 Pages + 23 Images + 8 Tables + 9 Attachments Background of Research: Technically, in order to ensure the quality of CT scan image can be accordingly guaranteed, as well as to keep the radiation dose below the specified limits, a qua…
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 kV…
