For Live and stored – image fluoroscopy before, during and after surgery, the BV25 has the capability of storing images for video hard copy documentation. Also provide radiographic documentation when required.

Specifications:

X-Ray Source

X-ray generator: DC converter – generator.
X-ray tubes – focal spots: dual-focus stationary anode 0.6 and 1.8

Fluoroscopy

Image intensifier: 15cm (6 in)high quantum absorption model with fibre output.
TV camera tube: VIDICON with fibre input.
Optical coupling between image intensifier and TV camera tube: glass-fibre optics.
Source of image distance: 90 cm.
Dose rate control: Automatic, simultaneous kV/mA control with lock and manual override facilities.
KV/mA range: from 0.1 mA at 40 kV to 3 mA at 100 kV.
Focal spot:06.
Grid: Fixed circular grid 44 lines/cm, ratio 8, SID= 90 cm.

Collimator

Iris Diaphragm: electronically controlled iris diaphragm, automatically limited to size of image intensifier input field (15 cm 0). Remotely controlled and steplessely adjustable to a field size of 5 cmdiameter at input field image intensifier.
Shutters: two parallel shutters of 0.5 mm Cu, remotely controlled and steplessely adjustable to a field of 1 to 16 cm wide at range intensifier. The shutters can be rotated+ 90 degree, in the mid position, the slit aperture is perpendicular to the length of the generator housing.

TV System

XTV 5 50 Hz: 625 lines,
60 Hz: 525 lines.
Bandwidth:15 MHz,
Control: AGC feedback to dose rate control system.
Video monitor(s): 51 cm (20”)screen motorized, remotely controlled image rotation and revesal. Output signal for recording system: outpout level of the composite signal always 1.o Vp-p positive across 75 ohms.
Measuring field selection for adapting control mode to the objects to be examined: small measuring field: 0.3 X diameter of TV image, e.g. extremities.
Intermediate measuring field: 0.5 x diameter of TV image, e.g. bile duct and gall bladder. The measuring field is selected automatically as a function of the k V used.

C-arm Movements

Height adjustment: 50 cm, motorized.
Horizontal Movement: 20 cm.
Scanning in horizontal plane:12*1/2 degree to either side.
