5.16 Fusion Imaging
5.16.1 Overview
Ultrasound Fusion Imaging completes the matching of multiply modalities and overlapping for
ultrasound images and 3-dimensional data, such as pre-operative computed tomography
(CT)/magnetic resonance imaging (MRI) 3-dimentional 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 volume data to the Ultrasound System. CT/MR volume data will
be set as a CT/MR 3-dimensional cubic image. After the doctor registers the ultrasound real-time
image with a certain plane of CT/MR image, the Ultrasound System receives the probe position
information from ―positioning (probe) sensor‖. The Ultrasound System shows the CT/MR image
aligned with the ultrasound image in 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 image are displayed simultaneously via the spatial positioning device based on
the old lesion marks on CT/MR image. The lesion marks on CT/MR 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).
1. Fusion imaging is an optional function. Configure ―Fusion (software optional)‖,
―Fusion RESP (software optional)‖, ―Fusion Imaging Kit (hardware optional)‖,
Motion Sensor Support (hardware optional) first before conduct the Fusion
Imaging exam. See also Chapter 2.5.3 Option for details.
2. Only the probe C5-1E/SC5-1E/SP5-1E/L14-5WE supports Fusion Imaging in
B/Color/Power/Contrast mode (non-cardiac contrast mode).
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.
