Probes and Biopsy 13-49
Dispersion of the ultrasound beam
To avoid this problem, note points below:
Do not rely only on the echo of the needle tip on
the image.
Pay careful attention to the target
object, which should shift slightly when the biopsy
needle comes into contact with it.
Before you perform the biopsy, please evaluate the
size of
the object and confirm if the biopsy can be
carried out successfully.
Refer to navigation device accompanied manual about installation, operation and
disinfection of navigation device. Contact navigation device manufacturer if necessary.
During needle navigation guiding procedure, please keep the navigation device,
ultrasound system and the probe away from electromagnetic interference, such as: power
filter, signal indication, magnetic materials, cellphone and metal instruments. Otherwise,
navigation may be interfered.
Frontal side of the magnetic navigator should directly face the lesion. Distance between
the magnetic navigator front part and the target should reaches 20-66cm within the scope
of 30cm from left to right, up to down. Otherwise, magnetic signal is unstable for
navigation precisely.
Check stability of magnetic navigator before conducting needle navigation.
The Fusion Imaging is contraindicated to the person wearing the internal pacemaker,
cochlear implant or nerve stimulator. People wearing the implant or intra-corporeal
devices should keep one-meter away when the magnetic generator starts working.
Needle navigation feature combines technology of real-time imaging and mini-magnetic locating to
provide GPS real-time guiding biopsy. Based on the sensors attached to the probe and needle,
magnetic navigator provides the related 3-dimentional orientation of the needle and the ultrasound
image plane.
There are two types of needle navigation: in-plane and out-plane. In-plane navigation applies to needle
path inside the ultrasound image plane and out-plane navigation applies to needle path not inside the
ultrasound image plane.
