6.15 Fusion Imaging
6.15.1 Overview
WARNING
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.
Ultrasound Fusion Imaging completes the matching of multiple modalities and overlapping for
ultrasound images and 3-dimensional data, such as pre-operative computed tomography (CT)/
magnetic resonance imaging (MRI) 3-dimentional data/position emission computed tomography
(PET) 3-dimensional data/ultrasound 3-dimensional data, etc. With the benefits of high spatial
resolution, wide field of view and free-interference of the air, it offers adequate diagnostic
information to the doctor.
Spatial Positioning: Import CT/MR/PET/freehand volume data to the Ultrasound System. CT/MR/
PET/freehand volume data will be set as a CT/MR/PET/freehand 3-dimensional cubic image. After
the doctor registers the ultrasound real-time image with a certain plane of CT/MR/PET/freehand
image, the Ultrasound System receives the probe position information from “positioning (probe)
sensor”. The Ultrasound System shows the CT/MR/PET/freehand image aligned with the
ultrasound image on account of the magnetic spatial navigation function.
Lesion Viewing and Marking: to show the lesions marked on the ultrasonic planes, the ultrasound
image and CT/MR/PET/freehand image are displayed simultaneously via the spatial positioning
device based on the old lesion marks on CT/MR/PET/freehand image. The lesion marks on CT/
MR/PET/freehand image appear on the ultrasound image in real time. It helps the doctor spot the
old lesion mark and perform the surgical plan to the tumor ablation.
Clinical applications: the lesions not-easily-detected in the ultrasonic exams; the panorama of the
large lesion not-fully-displayed in therapeutic ultrasound; surgical operations to tumor ablation;
biopsy and ablation to the liver neoplasms (enabled in the biopsy to renal tumor, lung neoplasms
and prostate).
6.15.2 Magnetic Navigator
NOTE:
• Place the set of the magnetic navigator away from the electromagnetic interference sources,
such as power filter, signal indication, magnetically activated metal materials, cell phone in the
use of the devices.
• Connect the magnetic navigator when the magnetic navigation controller is OFF.
• Exit Fusion imaging before reconnecting/disconnecting sensor from the magnetic navigation
controller. Turn off the magnetic navigation controller before connecting/disconnecting
magnetic generator.
Plug the auxiliary output power supply cable, USB data cable, magnetic generator and sensor(s) to
the magnetic navigator respectively following the arrow’s guide.
