5.16.9 Parameter Setting
The parameters of the Fusion Imaging are described below:
Nav System
Operation
Tap [Tracking System] to enable or disable the function.
CT/MR image and the ultrasound image build up the coordinate relation. The
sensor indicator becomes green (navigation signal state indicator).
Fusion Ratio
Description
Adjust the display ratio that the ultrasound image registers with the CT/MR image.
Operation
Rotate the knob beneath [Fusion Ratio] to set the ratio.
The adjusting range is -1 ~ 1 in increments of 0.1.
 0~1 represents that the ultrasound image registers with the CT/MR image; the
change of the fusion ratio appears on the right window side.
The larger the value is, the better the display effect becomes for the ultrasound
image registering with the CT/MR image; and vice versa. 0 only relates to
CT/MR image on the right window side and 1 only relates to ultrasound image
on the right window side.
 -1~0 represents that the CT/MR image registers with the ultrasound image; the
change of the fusion ratio appears on the left window side.
The larger the value is, the poorer the display effect becomes for the CT/MR
image registering with the ultrasound image; vice versa. -1 only relates to
CT/MR image on the left window side and 0 only relates to ultrasound image on
the left window side.
