Removing Circumference Artifacts

Circumference Artifacts are displayed in the Preview Screen as
horizontal lines in the Coronal and Sagittal views and a white partial
circle around the Axial View.

This artifact can be removed from the dataset by right clicking the
Preview Screen and selecting

Remove Stray Voxels from

Circumference

. The data is recalculated without the artifact.

Adjusting MIP, Centerline and Image Type

The following slice control bar is found in various views and
positions throughout the system software.

•

Center-Line Position -

click and drag the

Center-Line

Position

tool moves the displayed centerline of the selected

image. This changes the selected position of subordinate
images as applicable.

•

MIP/Radiograph Toggle Control -

clicking the

MIP/

Radiograph Toggle Control

toggles the images displayed

between MIP and Radiograph (refer to page 7).

•

Slice Thickness Control -

click and drag the Slice

Thickness Control right/left increases/decreases slice
thickness and spacing (respectively).

NOTE:

The Slice Thickness of each view is at the Voxel size

originally scanned. For example, if scanned at a 0.3 Voxel size, the
slice thickness is 0.3. If scanned at a Voxel size of 0.4, the slice
thickness is 0.4
