do not support DICOM Print may require a 
filming interface (purchased separately). 

To save further filming cost, the Operator 
Console can directly print to a postscript 
printer such as the GE Color Printer available 
as an option. 

ImageWorks 

ImageWorks software is designed to take 
advantage of the Lightspeed

16

 CT Scanner’s 

computer and image processor. This desktop 
environment includes image management and 
networking. 

Because some of the image analysis and 
display features of ImageWorks replicate 
those in Exam Rx, the next section describes 
only features that are incremental or 
significantly different. 

Image Analysis 

• 

Multi-Projection Volume 

Reconstruction

 (MPVR): Quick and easy 

way to generate volumetric images for CT 
angiography without thresholding data or 
removing unwanted anatomy. An entire 
volume is used to generate images in any 
plane, creating real-time frames of 
reference at the same time;  

• Clinical utility is extended via two 
additional modes:  

 MIPS - enhances contrast and improves 

visualization of calcifications 

 Average - generates 2D radiographic 

images; 

• 

Multi-planar Reformation

 (MPR): 

Provides real-time assessment of anatomy 
in offaxis planes. Sagittal, coronal, oblique 
and curved planar reformations available; 

• 

Batch reformatting

 can also be defined 

and executed for later viewing if desired; 

• Image Addition and Subtraction: Includes 
image addition of more than two images at 
a time;  

 

*Volume Viewer 

Volume Viewer is an innovative and 
powerfull suite of productivity enhanvers 

(Volume Rendering, Volume Analysis and 
Navigator) that includes :

 

• 

Dynamic Volume Review™ for Fast 
Screening 

• 

Curved Volume Of Interest 

• 

Protocol Management and Loading 

• 

Review Layout Presets 

• 

Multiple VR Objects Merge 

• 

Pseudo Surface Shading Mode 

• 

Predefined Cut Planes 

• 

Volume Rendered Navigator views 

• 

VR Preset save/recall 

• 

3D Rendered Lumen View 

• 

Automatic Path Tracking 

• 

Path Bridging (in case of occlusions) 

• 

SmartCursor™ for Easy Navigation 

• 

Synchronized Reformatted Views 

• 

Cut visualization mode

 

 

 

*Advanced Vessel Analysis 

Advanced Vessel Analysis is the ultimate 
tool to assess and quantify vascular 
structures, including stenosis analysis, 
stent planning procedures, post stenting or 
vascular surgery follow-up. 

• 

protocol driven tools to perform quick, 
flexible and accurate quantitative analysis of 
vascular anatomy 

• 

provides maximum, minimum and mean 
intraluminal diameter measurements  

• 

provides cross-sectional areas of true 
orthogonal sections of the aortoiliac systems 
at selected anatomical points 

• 

clinical benefits include: stenosis sizing, pre- 
and post- surgical assessment, stent 
planning 

• 

Measurements in % stenosis or mm of 
stenosis, and measurement of length and 
dimension of stenosis.  

 

Image Display 

• 

Magnifying Glass allows quick 2X mag 
window that can be moved over an image. 

• 

Image Scroll moves an image within its’ own 
window. 

• 

Groupings allow application of window/level 
values, magnification/minification, image 

scroll or flip and rotate to a user-defined 
image set. 

• 

Save State stores user-selected image 
orientation and window/level with each data 
set. 

• 

Window/Level values may be: 

• 

Preset to provide six on-screen instant 
window/level settings 

• 

Set independently for up to 16 images on 
the screen 

• 

User-modified in discrete or variable 
steps 

• 

Adjusted real-time on-image by holding 
down the middle mouse button and 
moving the mouse 

• 

Cine mode provides paging in up to 4 view 
ports of up to 128 previously-stored CT or 
MR images at full selected display frame 
rate.  For more than 128 images, display 
frame rate may be reduced. 

• 

Cine mode also provides temporal, spatial 
or manual playback loops. 

• 

Text Page 

Image Annotation 

• 

Image annotation and cursor are shadowed 
to permit ease in reading. 

Image Management 

• 

Images may be stored and retrieved via 
Magnetic Optical Drive (MOD) media using 
DICOM 3.0 format. This allows interchange 
with other imaging systems supporting 
DICOM 3.0 MOD media. Not all vendors 
implementation of DICOM 3.0 are identical, 
so please check with the manufacturer for 
compatibility. 

• 

Off-line retrieval of all image files. Images 
may be viewed as soon as they are restored 
from MOD.

 

• 

Image retrieval time is approximately 30 
images 512 per second.

 

VariViewer

TM

• 

VariViewer is an interactive axial review 
mode that can change the slice thickness 
reconstruction instantaneously. 

• 

The user selects the volume to be 
specifically analyzed and chooses the slice 
thickness to be displayed as axial images. 
The user can then save a number of recon 
images sets, viewing a large number of 
slices for pure axial review and filming.
