SYSTEM CALIBRATION IN AN MR SYSTEM

摘要

In a method for making calibration measurements in a magnetic resonance (MR) system, in order to acquire an MR image of an examination subject, wherein the MR unit has a computer for operating the MR scanner, and a system control computer designed to control multiple system components of the MR scanner, a preparation step is executed by the computer to prepare a first calibration step, in which a first parameter of a system component is matched to the examination subject via the system control computer, and to prepare a second calibration step, in which a second parameter of a system component is matched to the examination subject via the system control computer. The first calibration step is executed by the system control computer as is the second calibration step. The preparation step is executed by the computer to prepare one of the first or second calibration steps before one of the calibration steps is initiated by the system control computer.

1. A method for making a calibration measurement in a magnetic resonance (MR) apparatus, said MR apparatus comprising an MR scanner comprising a plurality of scanner components, a computer interface operable by a user, and a system control computer configured to control said scanner components, said method comprising:
in said computer interface, executing a preparation step, for an image acquisition by said MR scanner from an examination subject situated in the MR scanner, to prepare a first calibration step that will be executed by the system control computer to adjust a first parameter of one of said scanner components relative to the test subject, and to prepare a second calibration step, which will also be executed by the system control computer, to adjust a second parameter of one of said scanner components relative to the examination subject; and in said system control computer, executing said first calibration step and said second calibration step, with said preparation step being completed in said computer interface before one of said first and second calibration steps is initiated by said system control computer.
