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.

Abstract: The invention relates to a phantom for simple calibration and quality assurance in an MR tomograph, having a phantom body (2), measuring aids (10, 11, 12, 13) and an intermediate bottom (14) having an upper and a lower side, wherein the measuring aids (10, 11, 12, 13) and the intermediate bottom (14) are arranged in the phantom body (2) in at least four planes (6, 7, 8, 9) and a first plane (6) comprises as the measuring aid only the measuring fluid (10), a second plane (7) comprises as the measuring aid wedge-shaped elements (11), a third plane (8) comprises as the measuring aid marks (12) of known distance from one another, and a fourth plane (9) comprises as the measuring aid comb-shaped elements (13), wherein the measuring aids (11) of the second plane (7) are arranged on one side of the intermediate bottom (14), the measuring aids (13) of the fourth plane (9) are arranged on the other side of the intermediate bottom (14) and the measuring aids (12) of the third plane (8) are arranged in the intermediate
