method and recheneinrichtung in support of a radiotherapy treatment

摘要

procedures in support of a radiotherapy treatment of a moving area of a body by breathing of a patient of the target area, complete the following steps:- inclusion of a moving aufnahmegebiet by breathing in the target area, pointing magnetresonanzdatensatzes (8) using a magnetresonanzsequenz, in the phasenkodierungsrichtung (2) along a z direction and reading in different radial en ausleserichtungen (5) a to z direction vertical ausleseebene (3) is provided.on several atmungszyklen,- determination of the atmungszustand wiedergebenden atmungsparameters from the k raumzentrum magnetresonanzdaten measured for each point in the k - raumzentrum measure,- allocation of the magnetresonanzdaten of magnetresonanzdatensatzes (8) each one by the associated atmungsparameter atmungszustand described.identification of a bewegungsmodells, using the various atmungszustu00e4nden assigned magnetresonanzdaten and- use of the bewegungsmodells to identify at least one of ansteuerungsparameters and / or planungsparameters to strahlentherapiebehandlung.
