摘要： In a magnetic resonance (MR) imaging method and apparatus, multiple diagnostic scans are obtained of an examination subject during an imaging session. An initial reference scan of the subject is obtained at the beginning of the session and, as the session proceeds, an automatic determination is made before each diagnostic scan is obtained as to whether the immediately preceding reference scan is still valid, primarily be checking whether an amount of patient movement has occurred that renders the immediately preceding reference scan invalid. Either a new reference scan is obtained before the next diagnostic scan, or, if still valid, the immediately preceding reference scan is used for the next diagnostic scan.

摘要： In a computer-implemented method, device and system for controlling an imaging system, a specific absorption rate is calculated with a computation unit and an RF transmission signal of the imaging system is controlled with a control device. The process of controlling of the RF transmission signal includes disconnecting the RF transmission signal when a remaining period during which the RF transmission signal is harmless for the patient has been reduced to zero.

摘要： In a method for determining time windows in a scan sequence, in which values of setting parameters of a scan can be changed during a current scan without adversely affecting the scan data obtained with the scan, comprising the following a scan sequence is loaded into a control computer, that then determines the time windows in the scan sequence in which values of setting parameters can be changed during a current scan, on the basis of an analysis of useful coherences in the scan sequence. The determined time windows are stored or processed so as to be available to operate an imaging apparatus to execute the scan sequence.

摘要： In a method for operating a medical imaging apparatus having subsystems, a control protocol assigned to a scan sequence to be performed is provided to a control computer that determines sequence control data for the control protocol, which define different functional subsequences of the scan sequence. Different effective volumes are assigned to each functional subsequence, and current ambient conditions of the apparatus are determined for the sequence control data and associated effective volumes, for a series of states of physiological processes that occur during the scan sequence. Control signals for the scan sequence are determined from the sequence control data, the effective volumes and the current ambient conditions per observed state, that optimize the functional subsequences of the scan sequence locally. During the scan, at least one current state of the observed physiological processes is determined and the control signals used for the ongoing scan are determined from the stored control signals, dependent on the at least one current state.

摘要： In a method for operating a medical imaging examination apparatus having multiple subsystems, current ambient conditions in a scan volume of the apparatus are determined and stored in a global ambient condition parameter set. A control computer starts a scan sequence according to a selected scan protocol, and sequence control data that define different functional sub-sequences for the respective subsystems are provided to the control computer. Different effective volumes are assigned to each functional sub-sequence, and respective current sub-regions in the effective volume associated with the respective sub-sequence are determined, in which a volume optimization is to take place. Control signals for the scan sequence are calculated using the sequence control data, the global ambient condition parameter set, and the determined current sub-regions of the affected volumes, in order to optimize the functional sub-sequences at least with regard to the current sub-region of the assigned effective volume.
