DIGITAL
UROLOGICAL
SYSTEM



Th
ere is one D
igital
Urologic
Radiographic/Fluoroscopic System
s
to be
purchased as part of the
project
. In general terms, the primary system components shall be: a
6
0 kW,
single
phase high
frequency/multi
-
pulse generator and s
ystem controls configured for digital acquisition control; a
tilting (+
88
/
-
20

degrees) table with integral
, under
-
table fluoro carriage / over
-
table x
-
ray tube
tower

that moves under/over the patient
;
dual
high
-
resolution

monitors on the tower; a

1
2

inch,
triple field of view image intensifier;

a CCD high resolution camera for digital acquisition;
a
n x
-
ray tech digital work station w/ 1000
-
line

slave monitor
.


Self
-
diagnostic software, error alarms and the capability for modem linkup to perform remote
diagn
ostics and transmit phantom images to the vendor for evaluation of image quality shall be
integral to the system.


Automatic exposure control, automatic collimation, image processing, printing and routing,
and
DICOM 3.0 compatibility are required and inten
ded to increase productivity.


GENERATOR AND
CONTROL
S


The generator for

this system shall be a 6
0 kW,

single phase
, high
-
frequency/multi
-
pulsed unit.
Touch screen controls to include digital acquisition/control are desired.

Software architecture
that pe
rmits upgrade and integration of future applications is required.

Digital network
architecture self test and calibration functions along with on
-
line performance monitoring and
control are desired (note your capabilities). Error logging with software dia
gnostics for
monitoring the entire system, allowing storage of operator messages and service diagnostic
messages is desirable.


Preprogramming of exposure parameters for fluoroscopy, radiographic, and digital acquisition

should be permitted
.
Programmable
parameters
sh
ould
include: patient name/
protocol,
procedure name, patient size, size and shape of multiple
-
field fluoro sensing window, foca
l spot
size, fluoro kVp setting
, fluoro mA selection, fluoro field of view, fluoro dose/v
ideo gain
(multiple select
ions) and

pulsed
fluoro
scopy

rate
.
Pulsed fluoro rates must be available fro
m

30
down to 3.75
f
ps
. Heat load readout of x
-
ray tubes at the control console is desirable.


Controls for system movements, as
-
well
-
as exam parameters shall be available at the
remote
control console. Integrated
table

controls

and recall of table top positional memories

shall be
available
through a hand control at the table
.
A dual mode foot switch at the table shall
consolidate table operations, spot fi
lming, and fluoro into o
ne foot control.

DIGITAL UROLOGICAL SYSTEM

(cont’d)



TABLE AND IMAGING TOWER


The
imaging
table shall be a premium quality table and have +
88
/
-
20

degree tilt capability with
variable speed tilt con
trol
. The
cysto
tabletop shall have four
-
way
hy
draulic
movement. The
table should support a minimum 450 pound patient without loss of motion accuracy.

A moving
X
-
ray tube above and image intensifier below shall provide
a minimum
17” of anatomical
viewing coverage of the stationary patient.


A 12”, tr
iple
-
field image intensifier incorporating two magnification modes shall be housed
beneath the table. A CCD
-
camera with 1024 x 1024 x 12
-
bit depth shall accomodate digital
image acquisition. Direct digital
-
acquisition radiography with single
-
frame or rap
id
-
frame shall
be integral. Direct digital fluoroscopy with single
-
frame and rapid
-
frame
shall be provided,
including the option for real
-
time cine
-
loop acquisition (all in progressive mode). Pulsed
fluoroscopy over a wide frame per second range shall be

provided. Image “road
-
mapping” and
subtraction shall be integral.


An x
-
ray tube with heat capacity of approximately
35
0 KHU with dual focal spots and rotating
anode shall be integral to the tower over the table.
A servo driven fluoro beam collimator sh
all
be integral to the X
-
ray tube system.


Dual, high
-
resolution (1024 x 1280) SVGA monitors for fluoroscopy and endoscopic videoscopy
shall be mounted on the tower. An additional “flat screen” LCD monitor for endoscopy work
should be proposed as an optio
n.


Collision safety provisions should stop table movement at contact with obstacles during tilting.


An exam room remote control shall be integral to this subsystem, providing exam room interface
for image review, print/storage selection and sending image

print commands to processors or
laser cameras.


Images acquired in the fluorographic mode
shall be stored to the hard drive with storage of a
minimum of 2000+ frames required (specify the proposed system’s capacity)
. A preview image
shall be available
un
der 10

seconds after exposure and fully processed image no later than
20

seconds after exposure. Post
-
processing
shall be permitted
at the
tech/
acquisition workstation

and
shall include contrast inversion, zoom and roam, auto window, edge enhancement, imag
e
inversion, image rotation, image reversal, multiple image display, use of electronic shutters, and
image annotation. After an image is approved by the user it is automatically saved according to
the configuration set and uploaded to a laser imager or th
e network.


Standard Ethernet link for a DICOM 3.0 compatible network shall be accomodated for both
image transmission and printing.


Note: please investigate interface compatibility with the RIS and PACS networks planned and
report these capabilities.
