Scout Scan: when enabled, provides image to assist in defining the Measure scan region
Force initial scan on-axis: forces end point of initial scan to be on same Y-axis as the start point
Maximum degrees to snap final scan on-axis: This field defines the maximum degree of rotation of the
cursor box at the scan progress screen (following a scout scan) that will result in an on-axis scan. On-axis
scans are faster than off-axis scans.
Rotation of the cursor box to an angle greater than or equal to the
Maximum degrees setting will result in
scan data collection at that angle. Rotation of the cursor box to an angle less than the Maximum degrees set-
ting will result in an on-axis scan.
On-axis scans are scans taken with the start and end points on the same y-axis.
If the
Maximum degrees to snap final scan on-axis is set to 15, then Force on Axis will correct scout view dis-
play for scout scans that are up to 15 degrees off axis.
Scan Type Name: operator-defined; default is “Research” or “Small Subject”
