    • PROBLEM TO BE SOLVED: To enable SAR (specific absorption rate) to be apparently reduced and, irrespective of it, to achieve good image quality.
      SOLUTION: By forming a magnetic field having a heterogeneous first actual value, obtaining an excitation pulse using a heterogeneous maximum acceptance value, forming a magnetic field having a heterogenous second actual value which is smaller than the heterogeneous maximum acceptance value, and obtaining a middle position of a start pulse, the start pulse is divided into a first pulse section and a complement second pulse section, the first pulse section is made to correspond to each low energy section, the second pulse section is made to correspond to each high energy section, the time of the second pulse section is extended and amplitude is compressed a cording to the extension, and the second pulse section with extended time and compressed amplitude is made correspond to the excitation pulse. The mean position is decided to make the heterogeneous first actual value to be barely smaller than the heterogenous maximum acceptance value.

    • 要解决的问题:使SAR(比吸收率)明显降低,无论如何都能实现良好的图像质量。 解决方案:通过形成具有异质的第一实际值的磁场,使用异种最大接受值获得激励脉冲,形成具有小于异质最大接受值的异种第二实际值的磁场,并获得 起始脉冲的中间位置,将起始脉冲分成第一脉冲部分和补码第二脉冲部分,使第一脉冲部分对应于每个低能量部分,使第二脉冲部分对应于每个高电平 能量部分,第二脉冲部分的时间被延长,并且幅度被压缩以延伸到延伸部分,并且具有延长的时间和压缩的幅度的第二脉冲部分对应于激励脉冲。 平均位置决定使异质性的第一个实际值几乎不到异质最大接受值。 版权所有(C)2009,JPO&INPIT

    • PROBLEM TO BE SOLVED: To provide a method with which ideal excitation pulses for achieving desired magnetizations can be determined even for large deflection angles, taking into account further (linear and non-linear) limitations (in particular SAR limitations). SOLUTION: In a magnetic resonance apparatus having an RF radiating coil and gradient coils, and in a method for operating such a magnetic resonance apparatus, a drive sequence, determined for multiple time steps of a pulse sequence, is specified for operating the gradient coils of the magnetic resonane apparatus to time-dependently select regions of a selected slice or a selected volume of a subject. A non-linear equation system is then solved to obtain drive parameters for individual transmit channels of the transmit coil for each time step, with specification of a desired target magnetization, and dependent on the drive sequence specified for the gradient coils. The non-linear equation system is based on discrete values for time and space variable and, in addition to equations resulting from the Bloch equation, which are non-linear in their drive control parameters, includes at least one additional equation that describes boundary conditions for the examination of the subject.
