Method for determining movement and rest phases of a partial object that moves at times during a CT examination, and CT system

摘要: A method and a CT system are disclosed for determining movement rest phases of partial object that moves at times in an examination during examination. In least one embodiment, two different radiation sources used the comparative measurement, first source emits fan beam specific rotation angle instant, absorption said being measured beamwise fashion, second beam, same second, later likewise relative or between instants is deduced by comparing deviating values multiplicity spatially equivalent equidirectional beams proceeding from angular position sources.
