Automatic, localized in Vivo adjustment of all first‐and second‐order shim coils

Open access
Gruetter, Rolf·1993·Magnetic Resonance in Medicine

Abstract

The implementation of a “fast, automatic shimming technique by mapping along projections” (FASTMAP) on a 2.1‐Tesla whole‐body system is described. The method provides a localized adjustment of all first‐ (X, Y, Z) and second‐order (Z 2, ZX, ZY, X 2‐Y 2, 2XY) coils in 2 min. The time savings are achieved by mapping the magnetic field along six projections rather than from whole‐imaging data sets. An analysis of noise error propagation suggests that in 64‐ml volumes the residual linewidths obtained with the method are negligible when the signal‐to‐rms‐noise ratio is above 30. The initial application of the method to localized 13 C, 31 P, and 1 H spectroscopy of the human brain resulted in linewidths of ∼2 Hz for 13 C (144‐ml volume), ∼2.5 Hz for 31 P (36‐ml volume) and ∼4 Hz for 1 H (36‐ml volume) with symmetric and reproducible lineshapes.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
