Method and apparatus for determining induced flow adaptation of the imaging parameters of the three-dimensional magnetic resonance angiography for

摘要

In order to image the material flowing, magnetic resonance preconditioning pulse is applied in the upstream region (28). For scanning the object, the magnetic resonance data lines corresponding in each multiple slices along the vessel of (40 ₁ ... 40 _n) RF pulse calibration sequence is a (36 ₁ ... 36 _n) is performed by generating. The processor (54), RF in the spatial position according to the curve that depends dynamically on the subject (58), it is scanned fit the curve intensity (56), the slice group to determine the signal intensity for each slice I will adjust the pulse profile. In the imaging sequence following an inclined angle is adjusted, the image representation stored in the (64) (52), the memory data lines from each slice is reconstructed received (62).
