Figure 5.

(A) Measured noise correlation matrices of the 4 channel receive array on phantoms of the following circumferences—290 mm, 370 mm, and 410 mm. The coils were tuned on a phantom with a circumference of 370 mm. Measured in vivo noise correlation matrix. (B) Photograph of the in vivo measurement setup consisting of 4 non‐overlapped receive loops (a birdcage coil was used for transmit and is not shown on the image). (C) In vivo images of the knee. A magnified image of the cartilage is shown to demonstrate the fine structure.
