METHOD AND SYSTEM FOR THE RECONSTRUCTION OF PLANNING IMAGES

摘要

A method for the reconstruction of planning images is based on a plurality of first respiratory cycles of a patient and tomographic raw data recorded at the same time as the first respiratory cycles being received. A reference cycle is determined based on respiratory cycles of the patient, in particular based on the first respiratory cycles of the patient. A reference cycle is subdivided into temporally equidistant reference phases, a reference amplitude being associated with each reference phase. The reference amplitudes are not equidistantly scanned therefore. Furthermore, the first respiratory cycles of the patient are subdivided into first phases, the temporal positions of the first phases each being based on one of the reference amplitudes. Reconstruction of planning images based on first intervals of the raw data follows, wherein the first intervals correspond to the first phases.

1. A method for the reconstruction of planning images, comprising:
receiving a plurality of first respiratory cycles of a patient and tomographic raw data recorded at the same time as the first respiratory cycles; determining a reference cycle based on respiratory cycles of the patient; subdividing the reference cycle into temporally equidistant reference phases, a reference amplitude being associated with each of the reference phases; subdividing the first respiratory cycles into first phases, temporal positions of the first phases each being based on a reference amplitude; and reconstructing the planning images based on first intervals of the raw data, the first intervals corresponding to the first phases.
