1.5T HD Knee Array Coil Setup and SNR Test
Prerequisites
1 Legacy Phantom Setup
Procedure
- Place the 1.5T HD Knee Array, the phantom positioner, and the
phantom on the patient cradle as shown in Figure 1. Note the serial number of the coil.
Figure 1. Coil and Phantom Setup
- Position the coil in the cradle, connect the cable as shown
in Figure 2
Figure 2. Phantom Positioner Alignment Marks
- Being careful to align the connector pins, place the anterior
coil section onto the posterior coil section and latch into place.
(Figure 3 ) The scanner will not operate if the coil sections
are not latched correctly .

- Ensure that the coil is aligned and centered with respect to
the baseplate as indicated by the arrows on the baseplate offset scale.

- Perform the Multi-Coil Quality Assurance Tool.
2 Unified Phantom Setup
Procedure
- Place the lower section of the coil on the patient table as
shown in Figure 6.

- Ensure that the phantom positioner is aligned with the posterior
coil section as indicated by the marks on the positioner and the coil
(Figure 10)

- Carefully align the connector pins on the lower part of the
Coil with the upper part of the coil and latch both the coil sections
into place as in Figure 11. (The scanner will not operate
if the coil sections are not latched correctly).
