Positrons - - emission tomography graph and method for determining the applied dosage distribution in the case of a particle therapy

摘要

The flexibility and, as a result, the sensitivity of a positrons - - emission tomography apparatus (2) for determining a in the case of a radiation therapy to improve the applied dosage distribution, there are two about an axis of rotation (d) arranged detectors (10, 12) is provided, which extends in the radial direction (16) opposite one another and are mounted so as to be movable relative to one another.
