MCQA Test procedure for Express Coil suit

Prerequisites

1 Head Neck Array (HNA)/Posterior Array (PA) Check

Procedure

  1. Connect the HNA cable to Port B of MR System as shown in Figure 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.

  4. Perform the QA Check using Multi-Coil Quality Assurance Tool procedure.
  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.

    For coil layout, refer to Figure 16, Figure 17 and Figure 19 .

  6. Remove the anterior part from HNA coil, connect the HNA adapter, keep the phantom set as same as before, as shown in Figure 5.

  8. Perform the QA Check using Multi-Coil Quality Assurance Tool procedure.
  9. Take note of which Test# and which Sig_Img failed(if any). To determine which coil/s has issue, refer to the matrix below

    For coil layout, refer to Figure 16 .

  10. Remove the HNA Coil.

2 Anterior Array /Posterior Array 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. Make sure that the marker line between A, B are aligned with the space between the phantoms. It is as shown in Figure 8.

  6. Take note of which Test# and which Sig_Img failed(if any). To determine which coil/s has issue, refer to the matrix below.

    For coil layout, refer to Figure 18 and Figure 19.

  7. Place the AA coil on top of the phantoms. Make sure that the maker line between B, C are aligned with the space between the phantoms.It is as shown in Figure 12.

  11. Take note of which Test# and which Sig_Img failed (if any). To determine which coil/s has issue, refer to the matrix below.

    For coil layout, refer to Figure 18.

  12. Remove the AA Coil.
