Adjustment (Shim) Volume Display Options

In most brain imaging protocols at CFMRI, the adjustment (shim) volume is not manually adjusted and typically you do not see it graphically on the Rx window. If the adjustment volume display is left ON by a previous group, you will see a bright green border around the yellow Rx border. If you do not need to manually adjust the shim volume, you can turn the display function off by deselecting the adjustment volume icon on the Position Toolbar. In cases where the adjustment volume is manually prescribed, you must turn ON the adjustment volume display to manipulate the position and size of the shim area.
