Optimization of scanning parameters for multi-slice CT colonography: experiments with synthetic and animal phantoms.


AIM To determine the optimal collimation, pitch, tube current and reconstruction interval for multi-slice computed tomography (CT) colonography with regard to attaining satisfactory image quality while minimizing patient radiation dose. MATERIALS AND METHODS Multi-slice CT was performed on plastic, excised pig colon and whole pig phantoms to determine… (More)
