5 Technical Manual

Safety The user is requested to observe national laws concerning the use and installation of x-ray equipment. This equipment is not intended to function in an atmosphere containing explosive gas. A check of the reliability and efficiency of the apparatus every 12 months is recommended for the safety of both patient and operator. Worn parts may become dangerous; they must be checked and replaced by new ones. Before using the unit, the operator is to ensure that all safety devices are in working order. Only properly qualified Technical Department personnel is authorised to remove the protective housing of the apparatus. No modification is to be made to the apparatus without the authorisation of the manufacturer. The condition of the cables and connections is to be regularly checked; they are to be replaced if they show signs of wear. In case of any doubt, call the Technical Department.

Protection against Radiation For protection against radiation during exposures, the operator must always remain at a sufficient distance away from the generator by using the full length of the handswitch cable. The personnel must use the protection accessories for protection against radiation and respect the security rules. Wear an anti-X apron. Make sure that the patien t is fully protected in case of exposures near the reproductive organs. Protective clothes should also be worn by the persons that stay near the patient during the exposure. For the patient security, we recommend to use a distance from focus as large as possible, and advise the patient on the secondary effects that the X-Rays emission added can develop. Before each utilisation, the operator must check the leaded collimator. To do it, make a fluoroscopy, press on keys 24 and 23 (see page 10), and watch onthe screen, the openning and closing of collimator

Transport The equipment does not be moved without taking precautionary measures. For more information, please contact the representative of APELEM Company.

Ref : 81-40-001-F


Use in fluoroscopy The image intensifier and the X-rays tube are to be covered with protection bags to avoid any liquid getting inside. When switched on, the machine will always start up in fluoroscopy mode. If in the course of use you find yourself in a different mode, press the fluoroscopy mode key.

1

Manual fluoroscopy

The manual fluoroscopy mode is obtained when the automatic fluoroscopy indicator light is off. If this indicator is alight, just press either the corresponding key or one of the four kV- or mA-setting keys. The operator adjusts the high tension and anodiccurrent values using the appropriate keys so as to obtain a good operating image on the video screen, and thus disactivates the automatic mode if that was the mode the machine was in. If the mode is changed, the operator is informed by a short beep sounding off. If the automatic fluoroscopy mode is exited with the automatic radioscopy key there is no beep.

2

Automatic fluoroscopy

In the automatic mode, the operator does not need to adjust the high-tension and anodic current values; this is done by an electronic system which examines the video in a circular zone in the screen centre and adjusts the fluoroscopy settings to obtain the best image. There is two Automatic fluoroscopy mode : low-energy : from 40 to 120 kV and from 0.1 to 3 mA high-energy : from 40 to 120 kV and from 0.1 to 6 mA

3

Flash radioscopy

The flash fluoroscopy mode is used to obtain a highly contrasted image of the subj ect thanks to x-ray emission of short duration but high intensity. This operating mode can only be used if the subject under observation moves slowly.

Ref : 81-40-001-F

23 Technical Manual

The operator presses the fluoroscopy pedal and an x-ray emission takes place. Once an image is obtained, it is stocked in the memory and the x-ray emission ceases, even if the operator continues to press the fluoroscopy command. After flash fluoroscopy, the machine returns automatically to continuous fluoroscopy mode.

4

Inversions of the fluoroscopy camera scan

In order to make the fluoroscopic observation easier, the direction of the camera scans can be inverted both horizontally and vertically. Right and left sides are inverted, or top and bottom. A configuration parameter is used to define the inversion modes active on start-up. The scan inversion mode required is selected by pressing the corresponding key. Each time it is pressed one of four idfferent inversion combinations is obtained. Two indicator lights indicate the activated inversions.

5

Digital video memory use This machine usually has two digital video memories.

The first memory is connected to the live TV monitor and enables the last image obtained to be frozen. If this memory is of the continuous integration type, the quality of the image can be improved by reducing the noise swarming. Memorisation is automatic and takes place each time the radioscopy control is released (L.I.H.!). The second memory is connected to the second monitor and enables to compare examinations with the first monitor by stocking, in the course of the observation, the diff erent images obtained. Two keys on the console control the functioning of his t memory: one key is used to transfer the image from the direct monitor to the copy memory, the other key is used to search for images. Both these keys may be activated at any time, during radioscopy or not.

Ref : 81-40-001-F


6

Remote control of video printer

The possibility of obtainingin a few seconds a paper copy of an image on the screen is given with the video printer. If your machine is equipped with a video printer, a print can be obtained at any moment by pressing the corresponding key on the keyboard.

7

Fluoroscopy timer This machine is equipped with a five-minute fluoroscopy timer.

After five minutes of x-ray emission in fluoroscopy mode, the timer must be reseted by pressing the corresponding key on the keyboard. If the fluoroscopic timer is not reseted, the fluoroscopy will be stopped and blocked, a beeper will bring this to your attention if you attempt to start another fluor oscopy by pushing the pedal. During fluoroscopy, you are informed that one minute has been spent by a short beep. When you have only 30 seconds left, a beep will sound every second, and then when the time is up, a long beep will sound off and the stop light will come on. The fluoroscopy timer can be reseted at any time.

Table of the parameters Description of the configuration parameters :

The following list is a condensed description of the parameters. Please note the following : The displays and the keys normally used to set the high tension are used in the configurationthe mode theused parameter, whereas themode displays and the normally used to set mA to or select mAs are in the configuration to modify thekeys value of a parameter. Parameter n" 1: Starting time restriction When the machine is first switched on, the capacitors of the inverter are not charged. A few seconds are necessary for them to charge. Moreover, the numerical video memory requires a certain lapse of time to initialise. It is not advisable to request an x-ray emission during this phase. Parameter n" 1 is used to f ix the duration of the stop just after start-up. The entered value expresses the duration of the stop in seconds. The minimum value is 10. parameter 8 : NU Parameter n" 9: Radioscopy extension time This parameter is used to fix a certain extension time of the x-ray emission in radioscopy when the pedal is released, to ensure the proper functioning of the video memorisation process. The entered value expresses this time in hundredths of a second. The video memory of the machine retains only the final image when the radioscopy pedal is released. The radioscopy drive must be prolonged after release by the operator so that the memorisation cycle can be completed. The necessary extension time will vary according to the type of memory used. You must programe this parameter with as short an extension time as possible, without a blinking phenomenon occurring.

Ref : 81-40-001-F


Parameter n"12 : Radioscopy establishment time This parameter is used to define the time between the start of the fluoroscopy and the moment when a video image appears. This parameter avoids useless display on the screen when there is not yet an observable image. Only at the end of this time is a live image obtained on the TV monitor. The entered value expresses this time in hundredths of a second.

Parameter n"13 : Live memory time This parameter is used to define the time in pulsed fluoroscopy durring which the TV monitor will be on live. The entered value expresses this time in tenths of a second. The memory must receive a live command or else the memorisation cycle cannot take place, since the command %s electric signal always defines the memory state. N.B. The ways in which the different fluoroscopy modes develop are as follows: Normal radioscopy: time actions

tt==00.1 sec parameter

fluoroscopy requested x-ray emission commanded await for fluoroscopy establishment then display of live video

When the operator requests the stopping of x-ray emission: - eventual waiting time fixed by parameter 13 (minimum time of live video) - live video memory stops - memorisation cycle begins - await for the end of extension time for memorisation - then stop. Parameter n" 20 : Automatic fluoroscopy on start-up This parameter is used to fix the state of the automatic fluoroscopy key on start-up. Parameter n" 2 : Scan inversions on start-up This parameter is used to fix the scan inversions validated at each start-up. Parameter n" 48 : Reference video in high-energy mode This parameter is used to fix the reference video to be reached during automatic high-energy fluoroscopy use. Parameter n" 78 : Ref erence video in low-energy This parameter is used to fix the reference video to be reached during automatic lowenergy Fluoroscopy use.

Ref : 81-40-001-F

31 Technical Manual

Parameter n" 15 : Radiography preparation time This parameter is used to fix the preparation time of radiography. The entered value expresses the time in seconds. When a radiography is requested a certain lapse of time must be waited before the emission of x-rays, so as to give the tube%s filament the time to attain its nominal temperature. Parameter n" 16 : Stop after a radiography This parameter is used to fix the duration of the stop after a radiography. The entered value expresses the time in seconds. After a radiography the tube%s large filament must be left to cool down in order to prevent a considerable x-ray emission from a radioscopy request while the tube is still too hot. Parameter n" 17 : Auto-repeat! slow speed This parameter is used to fix the repetition speed of the slow auto-repeat keys on the console. The entered value expresses this time in hundredths of a second. Parameter n" 18 : Auto-repeat! fast speed This parameter is used to fix the repetition speed of the fast auto-repeat keys on the console. The entered value expresses this time in hundredths of a second. N.B. The keys used in the configuration mode have a repetition speed independent of the programming. Parameter n"19: Starting time for the Auto-repeat! This parameter is used to fix the starting time for the repetition keys after a continued press. The entered value expresses the time of continued press in tenths of a second before repetition is started. Parameters n" 23, 24: Heating radiography 45 ... 45 kV, 80 mA This parameter is used to define the heating of the big focal spot for the corresponding kV range. Param)tre n" 84 DSA : This parameter allows to define the APX type used ( compact or DSA version). DSA = 0 (DSA function not active). DSA = 1 (DSA function active). Parameter n" 85 dsa_int : This parameter allows to define the integration type at switching on DSA_INT = 0 (integration x 2) DSA_INT = 1 (integration x 4) DSA_INT = 2 (integration x 8)

Ref : 81-40-001-F


Parameter n" 86 ACQ_A : This parameter allows to define the active level of the ACQ A signal ACQ_A = 0 (active at low level) ACQ_A = 1 (active at the top level)

Process for the centring of the laser module NOTES : All necessary measures must be applied for avoiding damage to the pieces, particularly painted and visible pieces of the finished unit . These measures include protection and attention to the pieces during their handling, and during the cleaning of the work station. During all the mounting the unit must be stored in a place perfectly cleaned. Reference documents : Special tooling Pieces to be prepared : Preparing of the shift

WARNING : The setting of the unit must be realised only by qualified technicians. DANGER : The laser beam may be dangerous to patient and operator if it is saw in a front view (in its axis), and may create a burn of the retina. 1-Position the +C, in +face/profile position,, cable output 1 in upward position.(Fig1). 2 - Place the at 25 cm from the collimator output, in the X-rays axis, the hole of a ruler situated vertically. 3 - Center the laser centring cross at the middle of the input face of the intensifier. 4 - Set the fluoroscopy with a minimum of kV and Ma. 5 - Switch on the laser centring. 6 - Engage a fluoroscopy and move the +C, so as to visualise the leaded cross exactly in the centre of the ruler hole. This action allows to materialise the X-rays axis(fig.1and 2). 7 - Tighten the arms and check that the ruler is fixed in position. Check the X-rays axis. 8 - Adjust each arm support of the module so that the line generated by each of thus crosses the ruler in its centre, and also be superimposed with the corresponding line of the cross designed on the centring disk. 9 - If the centring has been yet realised in the factory, it is enough to set the two supports.

Ref : 81-40-001-F


10 - If the centring is made for the first time, you have to displace the two arm supports and to direct each module in order making the cross orthogonal, and also adjust the position of each module with the one of its output window. This window has a hole which allows to limit the dispersion of the laser beam out of the useful image intensifier field. 11- Check again the X-rays axis for compensating an inopportune decentring. 12 - Block the screws. as soon as the setting is realised. 13 - Check again the setting, and applied a varnish for blocking each screw. When you install the superior cover of the housing, take care of not knocking against the module support. NOTE : periodicity of the laser XR/centring : 6 months. X-rays axis

Preventive maintenance The user is requested to observe national laws concerning the use and installation of xray equipment. A check of the reliability and efficiency of the apparatus every 12 months is recommended for the safety of both patient and operator. Worn parts may become dangerous; they must be checked and replaced by new ones. Before using the unit, the operator is to ensure that all safety devices are in working order. Particular attention is to be paid to indicator and display lamps by using the lamp test!. The indicator lamp (x-ray emission) on the console is to remain alight only when the x-ray emission controls are pressed. If it does not go out, disconnect the plug and call the Technical Department. No modification is to be made to the apparatus without the authorisation of the manufacturer. Good earthing of the sockets is to be ensured. The condition of the cables and connections is to be regularly checked; they are to be replaced if they show signs of wear. In case of any doubt, call the Technical Department. The vertical displacement mechanics of the structure, the wheel movements, the mechanical brakes and the safety switches are to be checked once a year.
