User's Manual

1.1. Electrical safety

Only trained service personnel authorized by Villa Sistemi Medicali may remove the unit covers and only in accordance with the instructions contained in the Service Manual.

This x-ray unit may only be used in environments or medical rooms in compliance with the applicable IEC standards.

The x-ray unit must not be used in areas where there exists a danger of explosion.

Cleaning and disinfecting agents, including those used on patients, may create an explosive, gaseous mixture. Use only those products in compliance with the applicable rules.

1.2.Laser targeting devices safety

•Keep always a good lightening on the room.

•Never look through the output window of the laser targeting device.

•Never fix the reflections of the laser targeting devices.

•Before starting any examination, the patient must remove earrings, glasses, necklaces and whatever could reflect the laser beam and be printed on the image.

•Don't clean the openings of the laser targeting devices with tools that could modify their optics. Only the service personnel must perform possible cleaning actions.

•The min. distance between the laser source and the patient must not be lower than cm20.

The only purpose of the laser use is to reduce the patient dose to a minimum, it doesn’t be considered as an absolute means of centering.

The activation of procedures other those listed above can cause the emission of dangerous non-ionizing radiations.

1.3. Mechanical safety

The unit can be moved only by trained personnel by complying with the following safety conditions:

•Move the unit by considering the conditions for the movement that are indicated in detail in the paragraph 3.1.

•Don't move and use the unit on surfaces with inclination higher than 5°

•Only use the proper handles to move the unit.

•Avoid collision with obstacles.

1.4. Electromagnetic compatibility (EMC)

This apparatus is in compliance with the standard IEC 60601-1-2 that defines the max. allowed emission levels from electronic devices and the required immunity from interference caused by externally generated electromagnetic fields.

It is not, however, possible to exclude radio signals coming from transmitters such as mobile phones or similar mobile radio devices. These and other transmitting devices, including those in compliance with the EMC standards, may influence the proper functioning of medical apparatus when used in proximity and with a relatively high transmitting power. Therefore, the use of radio equipment proximity to electronically controlled systems must be avoided in order to eliminate any interference risk.

Any transmissions by mobile radio equipment must be avoided. Mobile phones must be switched off in zones close to the unit.

These rules must be applied when the unit is switched on (that is to say connected to the mains and ready for use).

1.5. Protection against ionizing radiation

Before any x-ray exposure, ensure that all the necessary protective precautions have been taken.

During the use of x-rays, personnel present in the room must comply with the following rules concerning protection against ionizing radiation:

When necessary, use protective shielding against radiation in addition to the shielding already provided on the unit.

Use protective aprons containing a material equivalent to 0,35mm of lead. Material of this nature reduces radiation at 50kV by 99,95% and at 100kV by 94,5%.

The best protection against radiation is distance. It is therefore recommended that you stay as far as possible from the x-ray source and the exposure target. For this purpose, use all of the cable length provided for the foot-switch.

Avoid walking or standing directly in the x-ray beam.

Always use the smallest possible field of exposure by closing properly the collimator diaphragms. The scatter dose produced depends principally on the volume of the irradiated object.

Never modify or disconnect the safety circuits or devices designed to prevent accidental exposures.

Collimation system adjusted to a field of 30 x 30 cm2 at 1 m from the x-ray tube focus. Exposure parameters: 100 kVp and 1 mA. Values normalized to 1 min. of fluoroscopy (µGy/min).

Equivalent water phantom 30x30x20cm.

The complete isodose measures are included into the report 035-07 ISO KERMA MAPPING (cod.200394) attached to the unit documentation

2.5. Handswitch for radiography / fluoroscopy control

The control handswitch is made of a twosteps switch.

Radiography mode:

1° step: preparation control. 2° step: emission control.

In radiography mode it is possible to press immediately the exposure control (2° step), with an emission delay due to the anode

starting phase (only for rotating anode version).

It is possible to control Fluoroscopy and Storage even with the radiography handswitch.

Fluoroscopy mode:

1° step: fluoroscopy control. 2° step: image storage.

Normally the function is enabled. In order	Fig. 14

1Indication of the dose value (only if the dosimeter is present and in working condition / MESSAGES and/or ERRORS Area)

2Indication of the FLUOROSCOPY / RADIOGRAPHY phase.

3Indication of the available thermal units (HUT), expressed in percentage from 0% (indicator completely white and spent HUT) to 100% (indicator completely black and available HUT).

When the residual HUT value allows a use of the unit below five minutes, under the indicator will appear also the residual time indication (t = …min), valued in function of the employed power. Simultaneously it’s issued an acoustic alarm not modifiable.

When the residual HUT reach 0%, the x-rays emission block intervenes.

It’s possible to exceed this limit and proceed with the x-rays emission (only in fluoroscopy mode) till intervention of monobloc thermal security.

This choice must be performed by Service personnel and on express request of the final user.

As the monobloc temperature decreases, the HUT will be regenerated. Residual time indication will disappear, when thermal units allow a use exceeding five minutes.

4Selection of the Anatomic Curve in Fluoroscopy (Standard / Paediatric / Pelvis-Head /

Standard for sturdy patient (only for rotating anode with camera 1K2)).

5Indication of the set kV value. It changes in Automatic mode or in Manual mode by using the kV+ and kVkeys of the control panel.

6Indication of mA value concerning kV and the selected curve. During the exposure it indicates the measured mA value.

7Indication of the AUTOMATIC / MANUAL mode.

8Dose printing key. It appears if the dosimeter is present and in working condition and if the printing mode in Utility Mode is selected (§3.6.10).
