Claim One:
1. A method for correcting magnetic resonance (MR) signals acquired with a time-of-flight (TOF) MR angiography technique, said method comprising the steps of: acquiring MR signals in a target volume using TOF MR angiography to generate multiple MR angiography images; in a processor, identifying pixels having a background signal in the respective MR angiography images by separation of said pixels from noise and vessel pixels; in said processor, determining a signal profile of said pixels with background signal across an entirety of the target volume; and in said processor, normalizing the MR signal for a predetermined set of pixels of the target volume with the signal profile of the pixels with background signal, to produce a normalized MR signal, and normalizing the MR angiography images dependent on the normalized MR signal, to produce normalized MR angiography images.
