9 eSieFusion Imaging
Instructions for Use 9 - 3
eSieFusion Overview
WARNING: This feature uses reference data collected using other imaging modalities.
Variability in system performance, operator technique, patient characteristics, patient movement,
and other factors may affect image alignment and sensor tracking data. At all times, the clinician
is advised to carefully review the on-screen data and confirm the information presented with
clinical judgment.
WARNING: The tracking system generates magnetic fields that can interfere with implantable
devices such as pacemakers and implantable cardioverter-defibrillators (ICDs). If the patient has
such an implantable device, you should be aware of any interference in its operation and
immediately power off the ultrasound system.
WARNING: Percutaneous procedures always involve heightened risk to the patient and to the
operator. Clinicians using biopsy or ablation devices under ultrasound guidance should be
trained and must observe proper procedures when attaching tracking sensors to the transducer
or the needle to avoid inaccurate tracking or alignment.
eSieFusion imaging enables viewing of a real-time ultrasound image aligned with reference
data acquired using another imaging modality, such as computed tomography (CT) or magnetic
resonance imaging (MRI). You can use the blended image for visualization during diagnostic
ultrasound exams, ultrasound-guided ablation procedures, and ultrasound-guided biopsy
procedures.
The eSieFusion feature is compatible with the following transducers and exam types.
Transducer Exam Types
4V1 Abdomen, Renal
4C1 Abdomen, Renal
6C2 Abdomen, Renal
9L4 Musculoskeletal
The eSieFusion feature requires the following tracking system equipment.
Equipment Description
Electronics unit
Provides connections to the transmitter, the transducer sensors, and
the needle sensor.
Transmitter
Connected to the electronics unit. Generates a magnetic field for
determining the location of the transducer or needle.
Transducer sensor
Attached to the transducer and the electronics unit. Provides location
and orientation information to the tracking system.
Needle tracking sensor
Inserted into the needle and attached to the electronics unit. Provides
location and orientation information to the tracking system.
