SVD-based
coil-combination improves SNR in metabolic imaging of hyperpolarised 13C
compounds and is robust enough to be included in a fully automatic processing
pipeline.
Fig. 1: Comparison of different coil combinations in a kidney cancer patient acquired
with an 8-channel receive coil (average of time steps 3 to 10; slice 3 out of 5
slices).
Fig. 2: Sensitivity maps in the same kidney cancer patient as in Fig. 1 (real part only) acquired with eight 13C receive channels: raw receive sensitivities after SVD calculation are shown in the top row (“bare SVD”) and the sensitivities after polynomial smoothing and channel normalisation in the bottom row (“SVD+”).
