DICOM Conformance
Standards:
•
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.
• Define both internal and external scan
planes to ± 1 mm accuracy.
• DICOM 3.0 Storage Service Class
• Operate over full range of gantry tilt;
activated any time during exam (with tube
stationary).
Image Networking:
• Service Class User (SCU) for image
send
Exams can be selected and moved from
MR Signa Advantage, CT HiSpeed
Advantage, Advantage Independent
Console, Advantage Windows Workstation
to the Lightspeed
16
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
16
creates
images in pure DICOM format, exams
can
not be moved from the Lightspeed
16
CT
Scanner System to MR Signa Advantage,
CT HiSpeed Advantage or the Advantage
Independent Console systems.
• Service Class Provider (SCP) for image
receive
• Coronal light remains perpendicular to axial
light as gantry tilts.
• DICOM 3.0 Query/Retrieve Service Class
Visual readout is easy to read from the table
side or from the operator console.
• DICOM 3.0 MOD Media Service Class on
1.2- and 2.3-GB MOD media
Gantry tilt controls are located on the side of
the gantry.
• DICOM 3.0 Storage Commitment Class
Push
• DICOM 3.0 Modality Worklist*
Table
• DICOM 3.0 Modality Performed Procedure
Step*
• Single table, cantilever design with wide
height range
• DICOM 3.0 Print
• Vertical Range: 51.6 cm to 99.1 cm
Filming Protocol:
Exams can also be selected and moved
between the Lightspeed
16
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.
• Vertical Scannable Range: 80.6 cm to 99.1
cm
• 3M-952 Standard
• Elevation Speeds: 5 mm/sec and 40
mm/sec
System Components
• Horizontal Range: 170 cm
• Horizontal Scannable Range: 170 cm
metal-free (axial) and 160 cm metal-free
(helical & Scout)
Gantry:
Image transfer time using either
AdvantageNet or DICOM 3.0 protocols is
approximately 0.1 second per 512 image
on a 100baseT Network.
• Horizontal Speed: Up to 100 mm/sec
Advanced slip ring design continuously rotates
generator, tube, detector and data acquisition
system around the patient.
• Table automatically recenters on scan plane
with changes in vertical position (after
setting internal landmark with alignment
lights on)
• Aperture: 70 cm
• Tilt: ± 30°
Computer Based Training
• Table Load Capacity:
• Tilt Speed: 1°/sec.
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.
• 180 kg (400 lb) with +/- 0.25 mm
positional accuracy
• Focus to Detector: 95 cm
• 205 kg (450 lb) maximum allowed with
normal operation and +/- 1 mm positional
accuracy
• 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.
• 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.
A well-indexed table of contents helps
speed access to information. The CD can
be viewed on the scanner or on a PC.
• Remote Tilt from Operator’s Console.
• Integrated breathing lights and countdown
timer.
• 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.
• Integrated start scan button with countdown
to X-ray on.
Industry Standards
Scan plane toward front of gantry for improved
positioning access.
X-Ray Tube
• The LightSpeed
16
CT Scanner System
complies with a wide variety of industry
standards to facilitate more rapid adoption
of features and performance
improvements as the computing and
medical imaging industry evolves.
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.
Performix ADV Metal-Ceramic Tube Unit.
Design optimized for exams requiring a
large number of scans without tube
cooling.
