Scout Scans
All these devices are free-standing and can be
easily moved to accommodate a large variety
of working conditions and individual operator
preferences.
Learning Solutions:
ScoutView™ scans provide excellent
detail for anatomical localization in
conjunction with scan prescription.
The LightSpeed
16
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.
Split table top allows unrestricted patient
viewing while still supporting 2 monitors. Each
work surface can be adjusted at installation to
help accommodate a variety of siting
requirements.
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.
Desktop Overview
Exam Rx
The user interface utilizes the paradigm of
managed work environments for a more
intuitive clinical workflow.
Scout Scan Parameters
Aperture: 1.25 mm effective aperture
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.
Xtream
TM
technology
enhances multi-tasking
architecture and maintains simultaneously all
processes so no work is lost or disrupted as
desktops are switched.
Patient Scheduling
Table speed: 100 mm/sec.
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.
Scan Technique:
•
kVp: 80, 100, 120, 140
•
mA: 10 to 440 in 5 mA increments
•
Power: 0.8 to 53.2 kW
