About this task

Follow this process to prepare for the MCQA test. This procedure can be performed using either a flat table or a curved table. Each table has its own coil. Use the correct coil for the table you are using.

  • (For curved table) 3.0T HD 8-Channel Wrist Array by Invivo, catalog number M3340CA

  • (For flat table) 3.0T HD 8-Channel Wrist Array by Invivo, catalog number M7000GW

Note:

Coils do not ship with phantoms. Phantoms come in a unified phantom set with the MR system.
