EVA Series are controlled by Digital key panel console that displays KV, mA and mAs with APR meuu
programmed. System-self-diagnosis and self –diagnostic circuitry standard on each unit. Equpped with
closed loop for X-ray tube current as well as kVp, minimizing potential errors and need for re-adjustments.

Microprocessor controlled high frequency generator for all examinations in the area of the X- ray
diagnostics, prepared for special applications. The automatic exposure control (AEC) is integrated. This
generator features by a very compact design and can be integrated in the base of the examination table
as a space saving compact solution.
The foil coated control desk enables easy operation and hygienic possibilities for cleaning as well as easy
operation for the user. In the anatomical program operating mode can be stored programs individually.
An internal self-diagnosis centre monitors the X-ray unit and indicates errors on the screen. So the
generator is optimal protected against malfunctions.

The radiographic examination unit EVA featured by an optimised construction which permits to realise a
multitude of examinations on a minimised room. The table is prepared to integrate a special X-ray
generator into the base. The complete system can be installed quickly and simple without additional
special construction works.
The examination table is composed of a Bucky table with floating patient table top and an integrated
column which supports the tube assembly, collimator and the control board. The column doesn’t need any
additional fixing elements.
The arm which supports the tube and the control board permits the rotation of the radiogen system on the
axe of the arm itself and enable to realise special positions with different angles of incidence as well as the
operating of a Bucky wall stand. The vertical movement of the radiogen system is balanced by
counterweights. The transversal displacement of the tube as well as the rotation of the column is standard
All movements of the column and the table top are stopped by electromagnetic brakes.
The top panel of the Bucky table is in radio transparent laminated plastic with longitudinal profiles in
extruded aluminium and lateral guides of insertion and anchorage of the accessories of common use. The
movements of the table top are stopped by electromagnetic brakes which are active in the absence of
power. They keep it in a defined position as well the installation is off.
The Bucky diaphragms of the table as well as the wall stand can be equipped with AEC ionisation
measurement chambers.
