Image Optimization 5-141
Image Magnification
Description
The lesion or tumor ultrasound and CT/MR image becomes clearer and easier to register
via <Zoom> key.
Operation
Rotate <Zoom> to zoom in or zoom out the image.
The parameter “Z” on the right side of the image refers to the magnification value. The
adjusting scale is: 0.8-2.0.
Toggling CT/MR Anatomical Plane
Description
The Ultrasound System sets CT/MR volume data to 3-dimensional image automatically
after importing Ct/MR volume data. There are transverse plane, coronal plane, sagittal
plane displaying from left to right at the bottom of the screen.
It is available to toggle and register among three planes.
Operation
Toggle [Steer] left. Toggle the CT/MR anatomical planes (among the sagittal plane,
transverse plane, coronal plane).
Cycling CT/MR Image Axially
Description
Rotate X/Y/Z to rotate CT/MR 3D image. Obtain the desired CT/MR plane to register.
Operation
Rotate <M>, <PW>, or <C> knob to cycle CT/MR image through X-axis, Y-axis or z-axis
in increment of 2°. The rotation range is 0° ~ 360° in increment of 2°.
See also Chapter 5.17.10 Rotating/Scrolling CT/MR Image.
Offset X/Offset Y CT/MR Image
Description
It is available to offset CT/MR image through X-axis and Y-axis and obtain a proper
position to register.
Operation
Rotate [Offset X]/[Offset Y] to offset the CT/MR image.
Scrolling CT/MR Image
Description
It is available to scroll one certain plane (sagittal/transverse/coronal) of CT/MR 3D image
on the Ultrasound System and obtain a desired CT/MR plane to register.
Operation
Rotate the multifunctional knob
to scroll Ct/MR plane.
See also Chapter 5.17.10 Rotating/Scrolling CT/MR Image for scrolling operations.
Window Width (Window W)/Window Level (Window L)
Description
It is available to set CT/MR image contrast via the window width.
It is available to set CT/MR image grey scale via the window level.
Window
Width
Rotate [Window W] to set the value in increment of 1.
Effect
The larger the window width is, the poorer the image contrast becomes.
The smaller the window width is, the better the image contrast becomes.
