Image Optimization 5-119
Five windows descriptions are given below:
When Fusion Ratio is among -1 to 0, the Ultrasound System registers
CT/MR image to ultrasound image. The fusion display appears then. See
also Chapter 5.16.9 Parameter Setting for fusion parameter adjustment.
When Fusion Ratio is among 0 to 1, the Ultrasound System registers
ultrasound image to CT/MR image. The fusion display appears then. See
also Chapter 5.16.9 Parameter Setting for fusion parameter adjustment.
R, L, A, and P imply the right, left, anterior and posterior of the patient.
R, L, H, and F imply the right, left, head and foot of the patient.
H, F, A, and P imply the head, foot, anterior and posterior of the patient.
Four indicators (1
st
indicator is on positioning (probe) sensor and 2
nd
indicator is on motion (abdomen) sensor. 3
st
indicator is on Needle
Navigation Guiding sensor. 4 indicator are reserved functions.)
Check the indicator becomes green in use.
Different indicator color:
Blinks green: excellent.
Blinks yellow: mediocre.
Blinks red: poor.
Stays grey: no signal activated. (Magnetic navigation is not
enabled.)
Note: if the signal of the sensor becomes poor, check the connections of the
magnetic devices. Reset the distance/orientation among the magnetic
generator, sensors and the patient. Exclude the interference from the metal
devices (ward beds made of metal materials) or the electromagnetic.
