摘要: In a magnetic resonance (MR) apparatus and an operating method therefor, a sequence with which the MR data are to be recorded is created in or provided to a control computer of the MR apparatus. A maximum RF output and a maximum gradient performance of the scanner magnetic resonance apparatus during the performance of the sequence are determined by simulating or analyzing the performance of the sequence in the control computer, and it is verified whether the maximum RF output and/or the maximum gradient performance violate predetermined limit values. Execution of the sequence to record the MR data is performed only if the verification showed that the limit values are not violated.

摘要: A method for automatically and dynamically optimizing image acquisition parameters/commands of an imaging procedure performed by a medical imaging apparatus in order to mitigate or cancel dynamic effects perturbing the image acquisition process of an object to be imaged by the medical imaging apparatus. The method includes connecting a dynamic correction module (DCM) to the medical imaging apparatus, automatically acquiring by the DCM image acquisition parameters/commands and data about dynamic changes or effects, and automatically determining in real time, by the DCM, at least one new image acquisition parameter/command from the image acquisition parameters/commands defined in the imaging control system and the dynamic change data, while the image acquisition parameter/command defined in the imaging control system remains unchanged. The method further includes automatically providing, by the DCM, the new image acquisition parameter/command to the hardware control system.

摘要: In a magnetic resonance apparatus and a method for operation thereof, at least one electrical operating value of at least one predetermined component of the apparatus is captured and, as a function of the at least one operating value, at least one coil operating value of a transmitting coil arrangement of the magnetic resonance apparatus is controlled for the purpose of limiting a B1 value.
