2D

Before you begin

A 2D series must be selected from the Workflow Manager and be in the INRX (In prescription) state.

About this task

Keep the following in mind when depositing slice location lines:
  • If the slice location lines that have been saved in a protocol are orthogonal, when they are applied to the localizer image the slices are applied in the same fashion that they were saved in the protocol.
  • If the slice location lines that have been saved in a protocol are oblique, when they are applied to the localizer image the slices are applied right to left. The start/end locations change to reflect this state. To obtain a left-right slice prescription that was originally saved in the protocol, the slices must now be rotated (3D or 2D), or erased and prescribed again (2D only).
  • To select a viewport other than the default viewport, click it to make it active.
  • You can only tilt the slices if oblique is the selected plane.
  • If oblique is the selected plane, each group of slices can have a unique orientation.

Use these steps to prescribe a 2D acquisition.

Step-by-step instructions

  1. Place the cursor in the viewport on which you want to deposit the slices.
  2. Click to deposit the first line of the 2D graphic tool.

  3. If the scan plane is an oblique, click and drag the Rotate handle to set the scan plane.
  4. Click and drag the Add handle to define the slice range.
  5. Click and drag any of the Scan Lines to move the group of slices to the desired location.
  6. Press Shift and simultaneously click for each group of slices you want to add to the prescription.
  7. Change the scan range parameters (FOV, slice thickness, and spacing) as needed to adjust the Graphic Rx.
  8. If you have selected SAT to deposit saturation pulses, to change the function of the left-click from SAT to Graphic Rx, click the Locs icon from the Graphic Rx toolbar.
    If you have a multi-slice multi-group scan prescription, the total number of slices is displayed on the graphic Rx viewport.
