摘要:
In a method for determining the ventilation of a lung of an object under examination by magnetic resonance imaging, at least two first lung-representing image data sets are acquired at different intervals of the breathing phase. The density change of the lung tissue is automatically determined from the signal difference between the image signals of the first image data sets in at least one corresponding region of the first lung-representing image data set. The lung or the thorax volume is automatically determined using at least two of the first image data sets, or using at least an additional second lung-representing image data set in a breathing phase that corresponds with the breathing phase of a first image data set. The localized, quantitative ventilation of the lung is automatically calculated depending on the density change of the lung tissue and the change of the lung or thorax volume.
摘要:
A control unit for an equipment arrangement is provided. The control unit includes an imaging modality, a measurement device for measuring a control variable and a controllable injection device for a regulatory substance influencing the control variable, wherein the injection rate of the injection device may be varied during a data acquisition such that a proposed value for the control variable is reached.

Disclosed is a control unit for a device arrangement. The control unit includes an image-generating modality and a controllable injection apparatus for a contrast agent. The injection rate of the injection apparatus may be varied during data acquisition as a function of a patient-specific cycle duration.
摘要:
The embodiments relate to a reconstructing an image of an examination object, a medical imaging apparatus, and a computer program product where a first image data record is acquired with a first imaging modality and at least one further image data record of at least one further imaging modality is provided. At least one first image is reconstructed on the basis of the first image data record using the at least one further image data record.
