摘要:
A method is disclosed for data acquisition and/or data evaluation during a functional brain examination with the aid of a combined magnetic resonance/PET unit. In at least one embodiment, functional image data of the brain are acquired in at least two activity states with the aid of both modalities. Further, magnetic resonance image data and PET image data are acquired within time windows determined by the activity states, the acquisition mode and/or the image data being synchronized as a function of a timing of stimulations determining the activity states.

A method is disclosed for determining attenuation values for PET data of a patient. In at least one embodiment, the method includes detecting at least one accessory of a magnetic resonance imaging scanner and detecting the position and/or alignment of the accessory by way of an imaging measuring method; comparing the detected accessory with data from a database; and assigning an attenuation map, which is contained in the database, to attenuation values of the detected accessory and adapting the attenuation map to the detected position and/or alignment of the accessory.
摘要:
A method is disclosed for operating a hybrid medical imaging unit including a first imaging device of relatively high spatial resolution and a second nuclear medicine imaging device of relatively high sensitivity that respectively acquire imaging measurement signals from a common examination volume. In at least one embodiment, the method includes determining the duration of the measurement signal acquisition of one imaging device as a function of the duration of the measurement signal acquisition of the other imaging device, which is defined by the occurrence of a specific truncation criterion.

A method for recording magnetic resonance image data of a patient ventilated by means of a ventilation apparatus is provided. The method includes assigning influencing information describing the effect of a respiratory movement on the image data recording to pulse sequence information, determining a magnetic resonance protocol for actuating a magnetic resonance device and a ventilation protocol for actuating the ventilation apparatus, and coordinating with one another in time, taking into account the pulse sequence information together with the influencing information, an imaging objective and a ventilation requirement, and actuating the magnetic resonance device and the ventilation apparatus in a time-coordinated manner on the basis of the magnetic resonance protocol and the ventilation protocol.
摘要:
A method for spatially resolved detection and display of movement processes in an examination subject by means of magnetic resonance tomography includes the steps of imposing a magnetization pattern on at least a portion of a fluid medium located in the intestine of the examination subject, acquiring at least one image data set or a portion of an image data set that images the region of the examination subject on which the magnetization pattern was imposed, determining at least one item of movement information from the at least one image data set or portion of an image data set, by an analysis of the magnetization pattern in a processor, and presenting the at least one item of movement information through presentation device in communication with the processor.
摘要:
In a method for recording a magnetic resonance image with a magnetic resonance device, in which several projection image data records are recorded in succession with different gradient orientations, from which, through back projection, the magnetic resonance image is reconstructed, the recording of a projection data record in a recording time frame proceeds with a temporal frequency modulated excitation pulse of a pulse duration, wherein, through the frequency modulation of the excitation pulse, all spins to be recorded within the scope of the projection data record are excited in a temporal sequence and wherein the frequency modulation function describing the frequency modulation during the pulse duration exhibits at least one maximum and/or at least one minimum. During the excitation duration, a time-resolved reception signal is detected. The projection data record is determined from the reception signal through evaluation.
