2.4 RADIATION PROTECTION

Because exposure to X-ray radiation can be damaging to the health, use greatcare to ensure protection against exposure to the primary beam. Some of theeffects of X-ray radiation are cumulative and may extend over a period ofmonths or years. The best safety rule for an X-ray operator is “Avoid exposure

to the primary beam at all times” .

Any object in the path of the primary beam produces secondary (scattered)radiation. The intensity of secondary radiation depends on the energy andintensity of the primary beam and the atomic number of the object materialstruck by the primary beam. Secondary radiation may be of greater intensitythan that of the radiation reaching the film. Take protective measures tosafeguard against this.

An effective protective measure is the use of lead shielding. To minimizedangerous exposure, use such items as lead screens, lead impregnatedgloves, aprons, thyroid collars, etc. Lead screens should contain a minimumof 2.0 mm of lead or equivalent and personal protective devices (aprons,gloves, etc.) must contain a minimum of 0.25 mm of lead or equivalent. Forconfirmation of the local requirements at your site, please refer to your “LocalRadiation Protection Rules” as provided by your Radiation Protection Advisor.

WHILE OPERATING OR SERVICING X-RAY EQUIPMENT,ALWAYS KEEP A DISTANCE OF NOT LESS THAN 2 METERSFROM THE FOCAL SPOT AND X-RAY BEAM, PROTECTBODY AND DO NOT EXPOSE HANDS, WRISTS, ARMS OROTHER PARTS OF THE BODY TO THE PRIMARY BEAM.

2.5 MONITORING OF PERSONNEL

Monitoring personnel to determine the amount of radiation to which they havebeen exposed provides a valuable cross check to determine whether or notsafety measures are adequate. It may reveal inadequate or improper radiationprotection practices and potentially serious radiation exposure situations.

The most effective method of determining whether or not the existing protectivemeasures are adequate is the use of instruments to measure the exposure.These measurements should be taken at all locations where the operator, orany portion of the body may be exposed. Exposure must never exceed theaccepted tolerable dose.

A frequently used, but less accurate, method of determining the amount ofexposure is the placement of film at strategic locations. After a specified periodof time, develop the film to determine the amount of radiation.

A common method of determining whether personnel have been exposed toexcessive radiation is the use of personal radiation dosimeters. These consistof X-ray sensitive film or thermoluminescent material enclosed within a holderthat may be worn on the body. Even though this device only measures theradiation which reaches the area of the body on which they are worn, they doprovide a reasonable indication of the amount of radiation received.

Eachtime a Film / Screen push-button is selected (illuminated), the others areautomatically deselected.

DENSITY: These push-buttonsareusedto adjust the radiographic film density.

Film density canbe proportionally increased or decreased inseveral steps.Theselected value is shown in the Density Display. The variation percentagedensity between steps can be changed during the equipment calibration by theengineer according to customer preferences (the percentage by default is25%).

AECRESET: If theexposure is abortedbytheAEC back-uptimer, theindicatoronthe“ AEC Reset ” push-button blinks accompanied by an audible alarm. The

next exposure is inhibited until the AEC function is reset by pressing the “ AECReset ” push-button. When the Generator is in “Prep” mode, the AEC functioncan not be reset.

The “ AEC Reset ” push-button may blink when the kVp value, the AEC Densityand the Film/Screen Combination select a technique that is out of the operativerange with AEC, inhibiting the next exposure. Change any parameter (kVpvalue, AEC Density and/or Film/Screen Combination) in order to obtain atechnique enabled for AEC.

4.7 ANATOMICAL PROGRAMMER (APR)

The Anatomical Programmer (APR) module is comprised of the controls whichselect the Patient Size and Display Selectors. The process is shown on the

APR Display.

The APR techniques are factory pre-programmed according to differentstandard techniques that combines six Body Regions with their AnatomicalViews (Organ + Projection). Besides the radiographic parameters, selectionsof the workstation or AEC can be assigned to the APR techniques. Theseselections will always be common for all the patient sizes of each Anatomical

View. These techniques may be modified and stored again by the operator inthe “ APR working File” .

The APR techniques are intended as a guide only. Accurate exposure factorsdepend, among other things, onBucky grid factors, table topabsorption, screenfilm combinations and film processing.

APR modeactivates when one of the three Patient Size (small, medium or largesize) is selected (push-button lighted), and deactivates by deselecting any ofthem.

APR language may be changed by pressing the “Power On”

push--button immediately after selecting one of the patient size

(APR activation). Language selected remains stored even after

the equipment is turned Off. Different languages available

according to order specifications.

If an APR technique is to be stored with AEC parameters, a

suitable back-up time (and/or mAs) MUST be stored in the

programme by the operator.

APR DISPLAY : Shows the different Body Regions and Anatomical Viewsavailable for each APR technique, and the final APR selection.

Because each area of the APR Display is limited in length to eight characters,some regions and views are abbreviated.

PATIENT SIZE: These push-buttons are used to adapt the APR techniquechosen according to patient size. Six patient sizes are available. The threeright-hand push-buttons select Small, Medium and Large adult sizes (only oneis illuminated when selected). The left-hand paediatric push-button changesthe function of the right-hand three push-buttons from adult patient size topaediatric patient size. (In this mode, the “Paediatric” push-button and one of

the other three buttons may be illuminated at the same time).

ANATOMICAL VIEW SELECTORS: Each push-button is related with thenearestareaof theAPR Display and they areusedto selectone of thedisplayedBody Regions, Organs and Projections. The selected Region and Viewsappears in negative block ( SKULL ).

The APR display shows the Body Regions, Organs and Projections. When a

Body Region has been selected its indication is locked on the screen and the APR Display shows directly all its respective Organs. In some cases, an Organmay show several Projections.

When theAPR selection is finished, the Consoleshows thefinal selection(APRDisplay), its respective parameters (RAD Display), the Workstation and AECcontrols related to the technique.

To go back to the previous level, press on the right-lower APR push-buttonwhich displays the “ return” symbol.

APR TECHNIQUE CHANGES

The APR techniques are factory pre-programmed to standard technique sets. All parameters of the APR techniques may be manually overridden as requiredby the operator and stored in the non-volatile memory for later use.

If the operator determines that some factors in an APR technique should bere-programmed, use the following procedure:

1. Select an APR technique and modify the factors and selections ofWorkstations or AEC which require to be re-programmed.

2. Verify that all factors of the technique are at the required values.

3. Store the new technique by first pressing the selected Patient Size andwithout releasing it press the Projection selected. (Refer to

Illustration 4-1).

The newly selected technique is now stored in the memory and can berecalled for future examinations.

This procedure only changes the technique values of the selected

patient size; repeat the procedure for other patient sizes.

To view theremainingHeat Units,press and hold the“On” push-button.ThekVpDisplay shows the percentage of Heat Units that remain preceded by the letter“H”. For example, a display of “H75” would indicate that 75% of Heat Unitscapacity of the X-ray Tube remains. “H -- -- ” indicates that all the capacityremains. The kVp Display reverts to its normal function after releasing the “On”push-button.

4.9 EXPOSURE COUNTERS

The operator can read the number of exposures made by the Generator, asindicated below:

Press and hold and press once

The number of exposures are shown on the kVp and mAs Displays, up to amaximum of 999,999 exposures.

kVp mAs

= 123,456 exposures

4.10 SELF-DIAGNOSIS INDICATORS

ERROR INDICATOR: Lights when a malfunction is detected in the system,alerting the operator that one of the following error inhibits X-ray exposures.Duringnormaloperation of the system, theseerror indicators are directlyshownon the APR Display or as an error code on the kVp Display. (Refer to Section

4.11).• Tube Overload (T.OVL): Indicates that either technique selected is

beyond the X-ray Tube ratings or the present conditions of the X-rayTube inhibit the exposure (anode overheated). Parameters for nextexposure may be temporally limited by the Generator (change theexposure values or wait for the X-ray Tube to cool).

Check that heat units available are lower than the ones calculated for thenext exposure (heat units close to zero). Reduce exposure factors orwait for the X-ray Tube to cool. (To display Heat Units refer to Section

4.8).

• Generator Overload (G.OVL): Indicates that the exposure wasinterrupted because arcing or malfunctioning occurred during exposure

on the HV circuitry (X-ray Tube, HV Transformer and/or HV Cables) ora failure of IGBT module (overheated or defective IGBTs) was detected.

It can also appear when making a lengthy or high powered exposure withthe X-ray Tube cool (X-ray Tube has not been sufficiently warmed-up).

• Rotor Error (ROTOR) : Indicates that the X-ray Tube anode is notrotating while “Prep” is active, then exposures are inhibited.

• Heat Unit (HEAT): Indicates that the X-ray Tube thermostat /

pressurestat is open due to overheating of the Tube housing (housing istoo hot; wait for the housing to cool) or to a thermostat / pressurestatmalfunction (housing is cool). Heat units may rise to any value.

• Technique Error (TECH): If activated during exposure it means that:

EXPOSURE HAS BEEN INTERRUPTED BY THE “SECURITY TIMER” BECAUSE OF A FAILURE IN THE SYSTEM. TURNTHE GENERATOR OFF AND CALL FIELD SERVICE.

This error can be also shown after an APR technique selection to advisethat exposure parameters displayed on the Console are not the valuesstored for this APR technique. Exposure parameters are adapted by theGenerator to enable other permitted values.

4.11 ERROR CODES

Error codes indicate the potential cause of a system failure. They areintermittently shown on the kVp Display at the same time an alarm sounds. Ingeneral, to remove the error indication on the Console keep pressed the “ AEC

Reset ” push-button till the alarm goes off. (Refer to Table 4-2).

All these error codes are preceded by the letter “E ” (i.e., E01) and they willenable the operator to indirectly convey the possible source of error to servicepersonnel. This may prevent the need for a service call or enable servicepersonnel to anticipate corrective actions prior to arriving on site.

SECTION 5 OPERATING SEQUENCES

5.1 START-UP ROUTINE

After turning ON the Console, the Generator will go through a start-up routineconducting an automatic self-test that will show information usable only byservice personnel.

After the power-up has been completed the Console should display normalradiographic factors. If there is a malfunction, error messages will be displayedon the RAD kVp Display specifying the fault.

Some indicators on the Console are used to provide service

information during the start-up process. These indicators should

be ignored by the operator until the unit has completed its

power-up sequence.

5.2 X-RAY TUBE WARM-UP PROCEDURE

Before effecting X-ray exposures ensure that the Tube is

properly warmed-up. Make sure that no persons will be

inadvertently exposed to unnecessary X-rays during this

procedure.

Routine exposures should not be effected unless the Tube is previouslywarmed-up, this prolongs X-ray Tube life.

ItisrecommendedthatthefollowingprocedurewillbeperformedforX-rayTubewarm-up, at the start of each day and when the Tube selected has not been inuse for approximately one hour.

This warm-up procedure is used for a typical X-ray Tube.

Consult the X -ray Tube manufacturer instructions for the

actual Tube in use, comparing its recommendations with this

procedure. If there is conflict with this procedure, comply

with the Tube manufacturer’s instructions.
