In a method for compensation of an out-of-balance condition of an imaging
data acquisition device, rotatable around a patient opening of a
stationary unit of a tomography apparatus, such as an x-ray computed
tomography apparatus or an ultrasound tomography apparatus, the data
acquisition device being rotatably mounted such that it can rotate around
an axis in a bearing of the stationary unit, vibrations transferred to
the stationary unit by the out-of-balance condition of the data
acquisition device, at least one of the out-of-balance vectors causing
the out-of-balance condition is determined from the vibration
measurement, and the axis of the data acquisition device is adjusted with
regard to an axis of the bearing to compensate the out-of-balance
condition.
