HNA Coil/PA Coil Check

Procedure

  1. Connect the HNA cable as shown inFigure 1.
    Figure 1. Connecting the HNA Coil
  2. Position the HNA and the phantoms as shown in Figure 2 and Figure 3. Make sure to use the phantom positioner and that the HNU pad is underneath the phantoms.
    Figure 2. Positioning the Phantom and the HNA 1
    Figure 3. Positioning the Phantom and the HNA 2
  3. Landmark on the HNA coil marking as shown in Figure 4
    Figure 4. Landmarking Coil
  4. Perform Multi-Coil Quality Assurance Tool to check SNR.
  5. Take note of which Test# and which Sig_Img failed(if any). To determine which coil/s has issue, refer to the matrix below.

AA Coil/PA Coil Check

Procedure

  1. Connect the AA cable as shown in Figure 7.
    Figure 7. Connecting the AA Coil
  2. Position the Phantoms on the cradle between marker 3 and marker 4. Make sure that the space between the phantoms is aligned with the line between marker 3 and marker 4. Place the AA coil on top of the phantoms. Center it as shown in Figure 8.
    Figure 8. Positioning the Phantom and the AA Coil 1
    Figure 9. Positioning the Phantom and the AA Coil 2
  3. Wrap the strap as shown in Figure 10.
    Figure 10. Wrapping the coil
  4. Landmark on the AA coil marking as shown in Figure 11.
