Scout Scans
ScoutView™ scans provide excellent
detail for anatomical localization in
conjunction with scan prescription.
Scan locations may be prescribed at the
operator console either graphically (via
mouse), or explicitly (keyboard entry) from
a Scout scan.
Prescription of scans with multiple gantry
angles are also available on a single
Scout.

requirements.

Desktop Overview

The user interface utilizes the paradigm of
managed work environments for a more
intuitive clinical workflow.
Virtually all clinical operations are managed
through three "virtual desktops" or applications
managers: Exam Rx, ImageWorks and
Learning Solutions. Operators can effortlessly
move back and forth between these
environments simply by clicking on an icon.

Exam Rx:
The Exam Rx desktop environment provides
the clinical tools necessary for comfortable,
efficient control of patient studies.
These tools include patient scheduling and
data entry, exam protocol selection, protocol
viewing and editing, scan data acquisition,
image reconstruction, image display and
routine analysis, AutoFilm or manual filming,
AutoStore and AutoTransfer.
ImageWorks:
ImageWorks is a desktop environment
designed to take advantage of the
16
Lightspeed CT Scanner System computer
and image processor.
Standard features include archive, network
and manual film control, as well as some
advanced image processing such as multi-
planar reformatting (MPR), multi-projection
volume rendering (MPVR), and MR image
display. It also has optional add-on packages
for Volume Viewer*, CT Perfusion2* and
DentaScan*.
The ImageWorks desktop also provides a
gateway for DICOM 3.0 image transactions,
either through a local area network, or via
DICOM-formatted MOD media.
Learning Solutions:
16
The LightSpeed provides an on-screen, on-
line operator manual via a multi-media CD-
ROM player integrated into the front of the
operator's console. Learning Solutions is also
viewable on a stand-alone PC providing
flexibility and productivity for on-demand
learning of system operation.
Exam Rx
Patient Scheduling
Patient demographics and exam protocols can
be pre-programmed in advance of patient
arrival by selecting Schedule Patient from the
scan/recon monitor. This productivity
enhancement allows entry of all or some of a
patient's demographic data, as well as pre-
selection of the exam protocol.
