Abstract/OtherAbstract:
|
The aim of this study was to analyze the reason for variation of image quality in the upper abdomen CT with the use of CT-AEC. The CT investigated was 3D modulation in the 16MDCT and LSCT phantom was used to simulate the patient. When there was a phase difference, an image noise increase of around 15% at the maximum was accepted. It is concluded that the major reason for variation in image quality is respiratory motion and the importance of respiration control must be recognized. |
