Abstract:
1. A combined positron emission tomography/magnetic resonance tomography (PET/MRT) unit, comprising: a magnetic resonance (MR) tomography unit including at least one basic field magnet, a system of gradient coils, and a high-frequency (HF) system, including an MR antenna, to generate HF excitation pulses and to detect emitted resonance signals, a measurement object being movable into the MR tomography unit in an axial direction; a PET detector including at least two detector elements to detect gamma radiation emitted from the measurement object, the at least two detector elements being arranged about the measurement object at a circular periphery and having at least a size such that gamma radiation formed on a line between the at least two detector elements in the measurement object and emitted in the direction of the at least two detector elements is detected; and at least one unit computer, including control software to process the emitted resonance signals detected by the MR antenna, and the gamma radiation detected by the PET detector, to store MRT data and PET data and to display MR images and PET images; wherein
