changes to be easily made, with virtually no 
restrictions; 
•  Enhanced multi-tasking allows operators to 
review more than one exam simultaneously, 
independently - even with AutoView and 
AutoFilm on/ 
•  Operator console convenient to locate in 
suite. 
•  Computer, image processor and image 
reconstruction hardware completely 
integrated in base of console - no 
separate computer cabinet to site; 
•  Be as self-teaching as possible, and have 
on-line access to tutorials as needed. 
•  BrightBox™ dedicated controls for 
image next, prior, manual paging and 
trackball W/L helps make two person 
image review practical; 
One key element of this design is to combine 
some of the best features from several 
product families into one state-of-the art CT 
system.  For example, the LightSpeed
16
 CT 
Scanner combines: 
•  Split table top allows unrestricted patient 
viewing while still supporting 2 large color 
monitors; 
•  Up to four 512x512 images from four 
different exams can be viewed on a large 
1024 color display. 
•  Front and back work surfaces can be set 
during installation within a range of 
vertical heights that help accommodate a 
variety of siting requirements - especially 
surrounding the height of the console 
relative to the window into the scanning 
suite. 
•  SmartTools productivity software to 
automate every step of the examination, 
critical for ensuring the highest productivity 
and throughput possible with the  
LightSpeed
16
 CT Scanner; 
•  SmartmA™  User Interface - automatically 
optimizes mA to maintain constant image 
noise when collimation/detector 
configuration, scan mode, scan rotation 
speed, table speed, or image thickness 
changes.  It takes the guesswork out of 
setting scan technique when changing 
parameters (note: user must select initial 
Noise Index as well as maximum mA 
setting). Noise index enable 100% Image 
Quality reproducibity from one patient to 
another and from one user to another. 
•  Large screen interface for controlling scan 
acquisition easily, with virtually everything at 
a single glance; 
•  Work surface accommodates a large variety 
of working conditions and individual 
operator preferences. 
•  Excellent simultaneity and multi-tasking 
performance; 
•  Wide work surface has room for papers, 
patient charts, logbooks or other 
peripheral devices; 
•  Completely protocol-driven scan control 
with a dramatic reduction in number of 
screens; 
•  Wide area also helps make two person 
operation more comfortable and 
practical; 
•  Protocol Pro™ protocol manager - provides 
operator control of automated features (like 
AutoFilm, AutoStore, and AutoTransfer) on 
per patient basis. 
•  Highly flexible editing tools that allow easy 
tailoring of the exam to the patient; 
•  All console components (monitors, 
keyboard, mouse and BrightBox) are 
free-standing and can be easily moved 
on the front work surface; 
•  Large, 1024 color display; 
•  Patient demographics and exam protocols 
can be preprogrammed in advance of 
patient arrival through the Schedule Patient 
feature. 
•  Leading edge, real-time image processing 
(MPR, MPVR, Volume Viewer*). 
•  All surfaces made of high-impact resin 
that hides marks and are easy to clean. 
In summary, primary benefits of Interactive 
CT on the  LightSpeed
16 
Scanner: 
•  A preprogrammed selection of AutoView 
and Image Review Layouts allow simple 
customization of the image presentation to 
match the anatomical area of interest - 
without the complexity of free-form 
“windows”. 
•  Direct network connection means a multi-
suite Ethernet card is not required for a 
gateway out of the suite - saving costs and 
simplifying installation. 
•  A natural scan control user interface 
•  Dramatic reduction in the number of 
screens; only 2 screens to set up first 
scan and 1 screen for real-time 
monitoring while scanning; 
•  Learning Solutions provides an on-line 
Operator manual detailing system operation 
via a multi-media CD-ROM player integrated 
into the front of the operator console. 
Learning Solutions can also be accessed on 
a stand alone PC providing flexibility and 
productivity for on demand learning of 
system operation 
•  ImageWorks™ provides instant access to 
advanced image processing features such 
as MIP, MPR, MPVR, Volume Viewer*, 
Advanced Vessel Analysis*, CT Perfusion 
2* and DentaScan*. 
•  Easier and more flexible protocols 
•  Much more flexible and intuitive graphic 
prescription process with a 1024 
Localizer; 
•  View/Edit Wizard™ intuitively adjusts 
dependent parameters automatically in 
response to operator-initiated changes 
and highlights them for quick review; also 
alerts the operator to incompatible 
dependencies requiring operator 
intervention; 
•  No waiting for network transfer or image 
retrieval from archive media. 
Advanced Tube & Generator 
Technology 
•  Background filming allows use of the full 
screen for AutoView and image 
review/processing without interruption when 
auto or batch filming.  Special “one touch” 
controls provide on-screen viewing of 
camera progress during AutoFilm without 
disrupting other image processes in 
progress. 
 
•  DynaPlan Plus™ full screen display 
illustrates scan status pictorially, with 
real-time feedback. 
•  The Performix  X-ray tube, with 6.3 MHU of 
storage and 53.2 kW operation, provides 
increased helical performance with greater 
patient throughput and virtually no tube 
cooling. Advanced technology in the 
Performix tube includes a metal-ceramic 
frame for long life, a high-speed bearing for 
sub-second scanning, a high-efficiency 
motor to accelerate the large anode and 
•  Large color screen 
•  ProView™ visualization algorithms 
available to enhance anatomical structures 
without additional image reconstruction 
time. 
•  Extensive use of picture icons and color 
cues enhance ease of use; 
•  Large on-screen controls and attractive 
color palette provide comfortable viewing 
over extended periods.
