校正呼吸影响的方法，磁共振器和存储介质
摘要：
本发明涉及一种用于借助磁共振器来校正对检查对象的拍摄的呼吸影响的方法、磁共振器和存储介质，该方法包括下述步骤：确定外部呼吸信号，确定内部呼吸信号，确定关联信号，确定关联信号的至少一个可靠性范围，确定关联信号的至少一个可靠性范围内的拟合函数和根据确定的拟合函数校正在检查对象的呼吸影响下的所述拍摄。在一个优选的实施方式中实现，在确定关联信号的至少一个可靠性范围内的拟合函数之后，实现拟合函数到至少一个如下区间上的扩展，即该区间不与关联函数的至少一个确定的可靠性范围相符，并且根据扩展了的拟合函数来实现对在检查对象的呼吸影响下的拍摄的校正。
摘要（英）：

An object of the present invention is to provide a method for correcting respiratory influences on photographing of an examination object by using a magnetic resonance device, the magnetic resonance device and a storage medium. In the method , an external respiratory signal is determined, an internal respiratory signal is determined, a correlation signal is determined, at least one reliability range of the correlation signal is determined, a fit function in at least one reliability range of the correlation signal is determined, and the recordings subject to respiratory influences of the examination object are corrected based on the determined fit function. In a preferable embodiment, after the fit function has been determined in at least one reliability range of the correlation signal, the fit function is extended to at least one range that does not correspond to the aforementioned at least one determined reliability range of the correlation signal. The recordings subject to respiratory influences of the examination object are corrected based on the extended fit function.
