5-62 Image Optimization
Type Parameters Description
Edit Depth Depth
Function: allows you to define the image depth to be cut. 3D
image changes in real time along with the depth.
Full: the full depth of the selected region will be cut.
Define: allow you to define the depth to be cut. When [Full
Depth] is “Off”, you can define the depth by clicking [Edit
Depth]. The range is 0%-100%, in increments of 5%.
Other
Operations
Undo To undo the last cut only.
Redo To restore the cut region.
Undo All To undo all cuts since you entered image edit mode.
Done Click to confirm the edit.
Tips: when reset ROI, entering cine review, exiting “Accept VOI”, unfreezing the system,
or entering acquisition preparation, the system will confirm with you “This operation will
clear all edit effect, are you sure to continue?”.
Reset ROI
 Function
Reset ROI is to reset the region of interest to re-render the 3D image.
It’s performed on frozen images.
NOTE: 1. Resetting ROI is not to re-capture images but to re-render 3D image with the
image data acquired already. Usually, if the ROI set before capture is not the
optimal one (e.g. the one contains the largest fetal face section area), you
can reset it to improve the 3D imaging effect.
2. Resetting ROI cannot improve 3D image with a bad imaging condition, such
as the un-optimal fetal posture s or lack of amniotic fluid, etc.
 Procedures
(1) Enter reset ROI mode: in Smart 3D image viewing mode, click [Reset ROI] in the
soft menu or the menu. There displays the original B-mode images marking with
ROI/VOI and progress bar.
(2) Adjust the ROI /VOI in size and position, for details; please refer to “Adjust VOI”.
(3) Set first frame/end frame: roll the trackball to view to a certain 2D image, click
[Set First Frame]/ [Set First Frame].
(4) After the ROI is reset, click [ReImaging] item in the soft menu to enter the 3D
viewing screen. The system will create a new 3D image based on the reset ROI.
In ROI resetting status, the parameters in the soft menu can be divided into image
acquisition parameter and image viewing parameter. Here,
 3 image acquisition parameters: Method, Distance or Angle, reset curve, their
functions and adjusting method are the same as the parameters in “Smart3D
Acquisition Preparation”.
 3 image viewing parameters: Set First Frame, Set End Frame, Auto Play, their
functions and adjusting method are the same as the parameters in “Cine
Review”.
