Image Optimization 5-41
ROI Tracking
Tap [ROI Tracking] to be On to start tracking.
This function provides a motion-compensated ROI as precise time-intensity information can be acquired
using active tracking.
Tip:
Elliptical ROIs can be positioned in any way that keeps their center within the image boundaries.
If part of the ROI is outside the image boundary, only data from within the image boundary is
used for calculating the mean intensity value.
When the user repositions an ROI, the old trace data is erased from the plot and the trace data
for the new position re-plotted.
X axis caliper
Rotate the hard key [X axis caliper] below the touch screen to select the different value to change the
display of X axis caliper. The tissue information can be located precisely.
Smooth
It is for smoothening the curve. The system provides 7 levels of smooth effect.
Export curve (save curve data)
1. Tap [Export] on the touch screen.
2. The dislog box appears. Then select the storage path and type the file name.E drive is default; and
the file type is .CSV.
3. Tap [OK] to complete the export.
After being exported successfully, a BMP. file shows on the thumbnail area.
The exported data include:
Current image;
Analysis curve data;
Analysis parameter.
5.11 3D/4D
This chapter includes multiple options. See Chapter 2.4.3 Options for details.
NOTE:
3D/4D imaging is largely environment-dependant, so the images obtained are provided for
reference only, not for confirming a diagnosis.
5.11.1 Overview
3D/4D is an option. The probe D8-4U/D8-2U/DE10-3U/DE11-3U/DE10-3WU supports static 3D imaging.
The ordinary 2D imaging has the limitations on viewing the overall structure and different planes of the
target. However, 3D imaging can obtain the reference information by overall observation.
Terms (see the graphics below)
Volume data: to obtain the data collection of three-dimensional object via the sequence
reconstruction to two-dimensional object.
3D image Volume Rendering (VR): the 3D image on the screen.
View point: the position for viewing volume data/3D image.
