Abstract

A phantom for calibration and quality assurance of an MR tomograph that comprises a phantom body with measuring aids and an intermediate bottom in at least four planes. The first plane contains only measuring fluid. The second plane contains wedge-shaped elements. The third plane contains marks of known distance. The fourth plane contains comb-shaped elements. The measuring aids of the second plane are arranged on one side of the intermediate bottom and those of the fourth plane on the other side. The marks of the third plane are arranged in the intermediate bottom. This arrangement enables reliable calibration of the MR tomograph in a few steps with only this phantom.
