Introduction
The LightSpeed
16
CT Scanner with
Xtream
TM
technology is the next step in
GE’s CT Continuum and its award-
winning LightSpeed CT platform. The
LightSpeed
16
CT Scanner routinely
acquires 16 sub-millimeter slices in one
rotation, at a scan speed of 0.5 seconds.
As with the very first LightSpeed product
introduction, the LightSpeed
16
utilizes
Designed for Six Sigma (DFSS
TM
)
methodology in all aspects of
manufacturing and engineering.
LightSpeed
16
is available both as a new
system or as a cost-effective upgrade to
an existing LightSpeed system.
Primary Benefits
• Routine use of sub-millimeter slices
without image noise or coverage
compromise.
• Small lesion and small vessels
assessments – pancreas, liver or circle
of willis, renal arteries, coronary arteries
and peripheral vascular arteries.
• The 6.3 MHU Performix X-Ray Tube
demonstrates the highest reliability and
delivers the power you need for image
quality. The Performix Tube now comes
standard with a one-year, non pro-rated
warranty.
• microVoxel
TM
imaging improves 3D and
reformatted 2D resolution through the
optimum choice of sub-millimeter slice
thickness and reconstructed voxel size.
• Unmatched Volume Image Quality
specification in all planes (sagittal, coronal
and axial): 15.4 lp/cm @ 0% MTF @ 0.5
sec. Rotation
• HiLight
TM
Matrix II Detector is designed to
deliver consistent image quality with its
21,888 individual elements: 16 rows of
0.625mm thickness and 8 rows of 1.25mm
thickness
• Xtream
TM
technology, a revolutionary new
workflow design, breaks through existing
limits on speed, image quality and flexibility
to provide an optimized workflow solution
from acquisition to final report.
• Lowest dose acquisition using SmartmA,
TM
an automatic modulation technique and DLP
display that tells the operator the dose
before the scan starts.
• HyperPlane
TM
reconstruction algorithm
tackles the inherent issues with fast, high
pitch helical scanning by reducing helical
artifacts and dose, and optimizing the slice
profile.
• CrossBeam
TM
reconstruction algorithm
solves the technical challenge of cone beam
artifacts.
• Large breadth of Advanced Software
Applications: Advanced Lung Analysis, CT
Colonography, Advanced Vessel Analysis,
Brain and Body Perfusion, Cardiac Analysis,
Cardiac Function, SmartScore Pro and
Advantage Sim.
• Compact system design of the
LightSpeed
16
allows for installation in only
28m² (302 square feet).
• Productivity features designed for the CT
Technologist: In-Room Start, Remote
Gantry Tilt, Breathing Lights with countdown
timer, Gantry Controls mounted on all four
corners of the gantry and an Integrated IV
Pole at the foot of the table.
• 1700 mm scannable range for full body
scans.
• 254 GB Disk (system, image, scan disks)
stores up to 250,000 512
2
images and 2881
scan data files.
• Cardiac acquisition with Segment, Burst
and Burst Plus enable you to scan patients
with heart rates from 40 to 110 BPM, and
provide for temporal resolution up to 65
ms.
• Color Coding for Kids, winner of a
National Heroes Award from the Emergency
Medical Services for Children, provides
pediatric scan protocols based on the
Broselow-Luten
TM
Pediatric System. This
Color Coding system is incorporated into the
protocol selection on the operator’s console
and is designed to facilitate pediatric
emergency care and reduce medical errors.
• VariViewer
TM
: provides an interactive axial
review mode that can change the slice
thickness reconstruction instantaneously,
resulting in the ability to “scan thin and view
thick.”
