• Batch film can typically enable you to reduce
filming images by 50%, thickening the slab
from 1.25 to 2.5mm with no information loss.
Image Networking:
Exams can be selected and moved from
MR Signa Advantage, CT HiSpeed
Advantage, Advantage Independent
Console, Advantage Windows Workstation
16
to the Lightspeed CT Scanner's Operator
Console. This is performed via the
AdvantageNet (GenesisNet) point-to-point
protocol. This protocol supports send,
receive and pull/query (no broadcast).
NOTE: Because the Lightspeed
images in pure DICOM format, exams can
not be moved from the Lightspeed
Scanner System to MR Signa Advantage,
CT HiSpeed Advantage or the Advantage
Independent Console systems.
Exams can also be selected and moved
16
between the Lightspeed CT Scanner
System and any imaging system
supporting the DICOM 3.0 protocol for
network send, receive and pull/query. GE
systems that support this interoperability
include CT HiSpeed CT/i, X/i, NX/i, QX/i,
MR Signa LX, and Advantage Windows
1.2/2.x/3.x/4.x.
Image transfer time using either
AdvantageNet or DICOM 3.0 protocols is
approximately 0.1 second per 512 image
on a 100baseT Network.
Computer Based Training
This innovative feature provides on-
screen, on-line support of Exam Rx and
ImageWorks functions via a multi-media
CDROM player, integrated into a tower on
operator console for easy access. Use of
rich graphics and text to provide truly
useful system help.
A well-indexed table of contents helps
speed access to information. The CD can
be viewed on the scanner or on a PC.

System Components

Gantry:
Advanced slip ring design continuously rotates
generator, tube, detector and data acquisition
system around the patient.
• Aperture: 70 cm
• Tilt: ± 30°
• Tilt Speed: 1°/sec.
• Focus to Detector: 95 cm
• Focus to Isocenter: 54 cm
• Maximum SFOV: 50 cm
• Rotational Speeds: 360° in 0.5, 0.6, 0.7 0.8,
0.9, 1.0, 2.0, 3.0 and 4.0 sec.
• Remote Tilt from Operator's Console.
• Integrated breathing lights and countdown
timer.
• Integrated start scan button with countdown
to X-ray on.
Scan plane toward front of gantry for improved
positioning access.
Biopsy and interventional studies have been
facilitated through a more streamlined gantry
shroud, and bilateral table/gantry controls and
gantry display that maximize maneuverability
while working next to the gantry.

Laser Alignment Lights:
• Define both internal and external scan
planes to ± 1 mm accuracy.
• Operate over full range of gantry tilt;
activated any time during exam (with tube
stationary).
• Coronal light remains perpendicular to axial
light as gantry tilts.
Visual readout is easy to read from the table
side or from the operator console.
Gantry tilt controls are located on the side of
the gantry.
Table
• Single table, cantilever design with wide
height range
• Vertical Range: 51.6 cm to 99.1 cm
• Vertical Scannable Range: 80.6 cm to 99.1
cm
• Elevation Speeds: 5 mm/sec and 40
mm/sec
• Horizontal Range: 170 cm
• Horizontal Scannable Range: 170 cm
metal-free (axial) and 160 cm metal-free
(helical & Scout)
• Horizontal Speed: Up to 100 mm/sec
• Table automatically recenters on scan plane
with changes in vertical position (after
setting internal landmark with alignment
lights on)
• Table Load Capacity:
• 180 kg (400 lb) with +/- 0.25 mm
positional accuracy
• 205 kg (450 lb) maximum allowed with
normal operation and +/- 1 mm positional
accuracy
• Controls on gantry for elevation and cradle
incrementation. Foot pedals on both sides of
table for fast elevation. Cradle position
controlled from OC for prescribed scans.
• IV Pole integrated at the foot-end of the
table prevents IV lines from becoming
crossed and tangled, and ensures that the
lines stay securely in place on the patient.
X-Ray Tube
Performix ADV Metal-Ceramic Tube Unit.
Design optimized for exams requiring a
large number of scans without tube
cooling.
