Advanced cardiac measurements and analysis
are transferred to the worksheet, and a result file with a
screenshot of the Bull's Eye will be generated. See also
section 'Reprocessing data' on page 8-38.
• If only one or two views have been analyzed, the tool will
enter the Quad layout of the most recently processed view
and prompt the operator whether the results should be
stored. If Yes is selected, measurements are transferred to
the worksheet and a result file with a screenshot of the
Quad screen is generated. See also section 'Reprocessing
data' on page 8-38.
The peak systolic strain detection for each segment can be
verified and manually adjusted as required. To adjust the peak
detection:
1. Press BE+Traces. The Bull's Eye and Traces screen is
displayed (see Figure 8-19)
2. To change the peak marker position on a curve:
• Click on the peak marker (square point) on one of the
curves, move the peak marker to a new position and
click again to fix the point.
• Place the cursor on a segment in the Bull's Eye. The
corresponding curve is highlighted. Click on the
segment to select the corresponding peak marker and
move it to a new position.
The peak type is determined by the selected color map (systolic
for PSS, global for PSI and TTP). The position of the AVC
marker can also be checked in the Bull's Eye and Traces
screen. If needed, the APLAX view should be reprocessed to
change the AVC time.
Be aware of the following:
• Clinical assessments should be made based on both color
and segmental full wall Peak systolic strain values.
• The export function is intended for research purposes and
should not be used to archive diagnostic data.
• No values shown in any Result screen will be transferred to
the Worksheet unless either Approve and Exit or Approve
and select next is pressed.
• All results shown (curves, colors and values) are based on
drift compensated values. Any strain drifting is linearly
compensated throughout the cycle. If the drift compensation
