Specification of 500 Ma X-Ray Machine

Specification of 500 mA X-Ray Machine

500 mA-125 KVP full wave solid state rectified X-Ray Generator for radiology with connectivity to image intensifier, single X-Ray Tube (Up-gradable to double tube), with buckeye table with spot film device.

X-Ray Generator

500 mA, 40 KW X-Ray Generator for Radiology/fluoroscopy/spotfilms Radiography KV Range : 40 to 125 Fu\fluoroscopy Range : 0 to 3 mA at 40/45 to 90 KV

Power rating of 500 mA at 100 KV/Radiography parameter from 40 to 125 KV range with ma & mAs range at small focus & large focus to be specified at all mA stations with THX 1 DRA Tube.

Generator Controls: Radiographic Timer Switch should have a timing range 0.01 to 5 sec.

Control should consist of:

 Push on/push off button with voltmeter, mA meter.  Technique control buttons  Selected focal spot display  Quick trip overload protector  Voltage compensator  Digital display blinking in case of overloading (Protection for Tube)  Space charge compensator  Technique selector  Digital display of active KVP, mA & mAs  Protective anode braking device  Electronic protection for overload of tube H.V. Cables & HT tank  Spot filming at all mA stations  Independent fluoro KVP selector  Pre heating on the both the focus during filament boosting for tube safety  Fluoro mA selector  Fluoroscopic timer: totalizer with buzzer  Bucky controls  Hand switch with flexible long cord  Serialography 2 frames per second

Main Panel should indicate:

 Incoming power line condition  Selected focal spot  Tube overload indicator-incase exposure factors exceed tube rating  Digital display of KV/MAs for radiography/spot filing selected

High Voltage Transformers

 H.V. Transformer comprising of HV Rectifiers, HT Transformer, Filament Transformer  Unit should have phase balancing transformer workable on 3 phase 415 volt AC  Power supply requirement should be 400-440 V AC, 50 Hz 3 Phase

Control & HT Transformers should be suitable for two tubes in future without added expenditure.

X Ray Tube:

 BEL DRA-1 double focus rotating anode Head THX 1 with DRA 1 125/20/40 tube unit 0.6 to 1.2mm. smaller focal spot will be preffered.  Aluminium filters  Light beam diaphragm with halogen lamp preferably auto shut off motorized collimator (as per BARC)  Pair of HV cables with standard length (preferably 10 meters)

Tube Column:

Should be floor to ceiling with fully counter balanced tube head with safety lock in case wire failure and capable of 360 degree convenient rotation and stops at 90 degree.

Lateral parking of fluoroscopy panel.

X Ray Table:

Motorized X-Ray Diagnostic Table with 90’ & 12’ movement alongwith spot film device with lateral parking for cassette size 8” x 10”, 10” x 12” and 14” x 14” with a grid 8:1, 40 lines per cm. All controls should be on SFD. Multi position with motorized bucky with bucky grid ratio of 10:1, 40 lines per cm with electro magnetic fully counter balanced floor to ceiling 360’ rotation with safety lock in case of wire failure.

 Fluoroscopic lead glass & screen assembly size 14 x 14  Grid 14x 14 inches (grid ratio & lines/inch should be specified)  Lead rubber flaps protective  Mark cones  Adopter format/adopting kit for 14 x 14 cassette  Lateral parking  Handgrip, foot rest, foot switch, compression band.  Motorized collimator with auto shut off system.
