The latest model / version of CT Sacnner available at the time of shipment should be provided inspite of
final quoted configuration.
Essential specifications of the proposed state of the art MDCT are given below.
The specifications mentioned are the essential minimum requirements of the tender. While the terms and
conditions are mentioned separately
Description
A State of Art Spiral Multi slices / Multi detector row CT Scanner capable of generating 128 slices per 360 0 rotation
with isotropic micro voxel imaging to perform whole body scanning (including trauma, vascular, cardiac, pediatric,
neurologic applications), the system should have at least 64 rows of detector with simultaneous generation of minimum
of 128 or more slices,
1 PATIENT TABLE
a) Load Carrying Capacity 180 Kg or more with positional accuracy of +/- 0.25 mm or less
b) Metal free scannable range of 150 cm or more
c) Mention the horizontal movement range and it should be sufficient to cover the patient from head to toe.
Also specify the horizontal speed
d)Specify vertical range, vertical scannable range and elevation speed.
e) Specify width and length of table – distance between gantry front and table base (min. & max.)
f) Automatic re-centering facility to the scan iso centre in all three directions should be available.
2 SCANNER GANTRY
a) Aperture minimum 70 cms or higher
b)Scan field of view in acquisition mode should be 50 cm. Specify minimum and maximum FOV with
increment values
c) Tilt : +/- 30 degree adjustable from gantry and console by remote
d) 3-D laser lights for positioning. Isocenter in all planes should be maintained ever when the gantry tilts
e) The gantry should be provided with user control panels on either side for easy positioning
f) Specify focus to iso centre distance and focus to detector distance
g) Specify the entire range of rotation time for 360 0 (lesser will be preferred).
3 X-RAY GENERATOR
a) High frequency type inverter based
b) Power output : 70 KW or more at 120 Kvp
c) mA range : 100– 600 mA or more
d) Kv range 80 to 130 or more.
e) Specify the max. mA allowed for 120 Kv for how long
4 X-RAY TUBE
a) Tube Voltage : 80 - 140 kVp or more
b) Anode Heat Storage capacity of at least 7.5 MHU or more. Alternatively the tube should have a high
dissipation rate of 1600 KHU/Min or more. Specify the dissipation rate also. And mention the details of
cooling system of the tube.
c) Specify the focal spot size as per IEC standard.
d) Source output of 70 KW or more.
5 SPIRAL ACQUISITION
a) Scan time should be 0.35 sec or less, for full 360 deg rotation
b) Specify the time in minutes for warm up from fully off in normal as well as in emergency situation.
c) Minimum slice thickness should be 0.625 mm or less. Specify minimum slice thickness in axial, spiral and
cardiac modes.
