Transcript New Power Point/Operation of the new Quantum HF Odyssey X-ray

Operation of the new Quantum
HF Odyssey X-ray Room
This room is used with the digital
radiography equipment.
The Quantum Equipment Features
• The Quantum Room features
– A more powerful generator with mA up to 600
mA for faster exposure and larger patients
– 0.6 and 1.2 focal spot x-ray tube for superior
resolution
– Tilting Wall Bucky for upper cervical technique
– Elevating Floating Table Top Table
– AGFA Digital Full spine Film Holder
Tilting Wall Bucky
• The Tilting Wall Bucky
will tilt 15º for
positioning the upper
cervical base
posterior.
• We still use the nonBucky film holder with
the Bucky.
• Note the chin rest for
chest radiography.
Tilting Wall Bucky
• The Bucky design allows
the patient to get closer to
the Bucky for lateral
views.
• A button on the handle
releases the lock to raise
or lower the unit.
• Buttons on the support
are used to angle the
Bucky.
Cassette Centering
• For the 24CM by 30
CM cassette or 43 cm
by 35 cassette
orientation, the
cassette is raised to
the center.
• The tray is calibrated
for proper placement
of the cassette
support.
Cassette Centering
• By centering the
cassette, the tray can
be pushed in sooner
and a notch on the
handle used to center
the beam to the film.
Full Spine Film Holder
• On the opposite side
of room to the Tilting
Bucky is the AGFA
Full Spine film holder.
• Three 35 cm by 43
cm cassettes are
loaded for full spines.
• The computer stitches
the images together
for digital full spines.
Full Spine Film Holder
• Note that we still use
the Nolan Filtration
System with the
digital system.
• We also have a
radiographic ruler to
perform scanograms.
Radiographic Table
• The table lowers to 21”
allow easy access for the
patient.
• It is then raised to
imaging height( 32.5”).
• The table top floats to
afford easy patient
positioning. Float control
is controlled by foot
pedals or handle at foot
of table.
Radiographic Table
• Both the Table and
Wall Buckies are true
Buckies with
osculating 200 line
grids.
• The Object Film
Distance is slightly
increased.
Table Bucky Tray
• Like with the Wall
Bucky, the film should
be centered but the
support is not
needed.
• The Bucky rolls about
3 feet to aide in
positioning
Tube Controls
• The tube angle has
an electric lock so do
not angle the tube
without pushing the
angle button.
• Lights come on the
tube when you are at
40” or 72” SID to
either Vertical Bucky
or the Table Bucky.
Tube Controls
• The Longitudinal Lock is
what we called the
Horizontal Lock in
Laboratory or on a
Universal Tube Stand.
• Do not touch the
Transverse Lock Button
when using the Bucky as
you can miss align the
tube to the Bucky with it.
Tube Controls
• The All Locks
Button will control
all of the locks at
once, including the
transverse and
angle lock.
• The collimator is
calibrated in metric
and English
measurements.
Tube Controls
• The Collimator has
a laser for film
centering.
• The tube angle
indicator is very
accurate.
SID Scales for Table
• There are two scales
for the Table SID.
• They are calibrated
for the full up table
top position.
• One is for the table
top and the other for
the table Bucky.
Wall Bucky SID Scale
• The Wall Bucky SID scale is on the floor rail.
Transverse Tube Angulation
• The tube may be angled across the table or in the
transverse plane.
• The scale is on the bottom of the tube support and the
lock on the top.
• We do not use this feature except to realign the tube to
the Bucky.
Quantum Odyssey HF Generator
• One thing you will
notice is the room
does not have a wall
full of technique
charts.
• All of our charts are
programmed into the
Anatomical
Programming of the
control.
Quantum Odyssey HF Generator
• The Quantum
generator offers more
user selections than
the Universal Control
Panel.
• You may select mA
and time instead of
just mAs.
• You need to select the
correct Bucky or Film
Holder.
Quantum Odyssey HF Generator
• It shows controls for
Automatic Exposure
but our unit is not
equipped with AEC.
• We will always use
the Anatomical
Programming feature
for setting technical
factors.
Anatomical Programming
• Select the region by pressing the button next to
the region.
Anatomical Programming
• Select the View by pressing the button next to
the View.
Anatomical Programming
• Use the buttons next to the arrows to enter the
patient measurements.
Anatomical Programming
• Adjustment for habitus can be made in 25%
changes.
Anatomical Programming
• Note that the focal
spot and even the
image receptor is
selected for normal
exams.
• For hips, lumbar
obliques and knees,
the image receptor
may need to be
changed.
Anatomical Programming
• When everything is
set, the ready light will
be on.
• Press the prep button
until it lights up. You
will hear the rotor
rotating.
• When the prep light is
on also press the
expose button to
expose the image.
