  • Method for rapid acquisition of spin resonance data for a spatially resolved investigation of an object
    Patent number: 4808928
    Abstract: The "spoiled FLASH" nuclear magnetic resonance (NMR) method avoids image artifacts which may be caused by transverse magnetization remaining at the end of a TR period of a partial experiment by applying an additional "spoiler" slice gradient pulse ("SP") after the detection of a gradient echo ("Signal") and before the application of the radio frequency pulse (RF) of the following partial experiment. The amplitude-time integral, i.e. the duration and/or the amplitude of the additional spoiler slice gradient pulses is incremented and/or decremented from partial experiment to partial experiment of a given total experiment. Each spoiler amplitude may be repeated after a time of the order of T.sub.2.
