Our phantom QRM-SSP is designed to test the slice sensitivity of a CT scannerís spiral/helical scan modes. It contains a 25 micron thick metal foil of circular area (diameter 1 mm), embedded in a cylinder of uniform tissue-equivalent plastic. The heavy-metal insert is designed to evaluate all collimations from 0.5 mm to 10 mm with adequate image contrast. We suggest to analyze the maximum CT number of the high-contrast insert for a series of axial images.
