About this task

This document details the “check scan” used at the conclusion of many procedures. This functional check assures the unit is in good clinical working order.

It is important to use a phantom with known geometry, such as the DQA Phantom, so the image can be analyzed for correct orientation.

Procedure

  1. Place the DQA III phantom on the Table.
    1. Place phantom positioner onto the hollow for HNU. R/L direction will be fit to the hollow.
    2. Push phantom positioner toward the magnet until the two bottom bars reach the end of hollow.
    3. Place DQA III phantom onto the phantom positioner and verify its orientation and levelness.
  2. Landmark on the center line of the DQA III phantom. The laser must be in the middle of the black circumferential line on the phantom. Press [Advance to Scan] button.
