METHOD OF GENERATING RF EXCITED PULSE TO EXCITE VOLUME HAVING ARBITRARY SHAPE, EXCITATION METHOD BY TARGETING SPINDLE IN BLOOD VESSEL, METHOD OF GENERATING PROJECTION IMAGE OF MR BLOOD VESSEL, AND CORRESPONDING MAGNETIC RESONANCE SYSTEM

摘要

The present invention relates to a method of generating an RF excited pulse (32) together with inclined curves (Gx′, Gy′) to excite a volume (35) having an arbitrary shape to a magnetic resonance system (5). The method includes: a step of, after a step of detecting an MR signal (33), preparing a volume segment (34) in which the volume (35) is placed to allow spindles in the volume (35) only to calculate the MR signal; a step of detecting the MR signal (33) from the volume segment (34) along a trace in a k-space wherein at least one slope (Gx, Gy) for scanning the k-space along the trace is switched during the detection; and a step of generating the RF excited pulse (32) corresponding to the MR signal (33) detected in a time-inversed method and generating the inclined curves (Gx′, Gy′) corresponding to the time-inversed curve of the slope (Gx, Gy) to scan the k-space.;COPYRIGHT KIPO 2014
