1.4 Int nd d us
The general-purpose diagnostic X-ray systems of the PRS 500-series are intended for various routine
applications in planar X-ray imaging in human medicine.
They are stationary systems that can be used both for analogue and digital imaging.
NOTE
At the acceptance test a 25mm Aluminium / ,5% purity can be used as a
phantom for a patient equivalent.
The acceptance test has to be made in accordance to the local laws and directives.
Only Special trained People are allowed to do this.
1.5 Indication and Contraindication
1.5.1 Indications
Justification of m dical xposur s
According to §23 of the German Radiological Ordinance (RöV), an X-ray examination is only justified if
the patients benefit from x-ray diagnostics outweighs the radiation risk. The examination method,
means the conventional X-ray with the PRS 500 system, must be suitable to answer the diagnostic
question and no other more suitable alternative method is available.
Accordingly, it is also described by the International Atomic Energy Agency (IAEA) in the document
Radiation Protection and Safety of Radiation Sources: International Basic Safety Standards (Requirement 37:
Justification of medical exposures). It also refers to the need to consider national or international
guidelines for the justification of a medical exposure.
A complete list of indications is unrealisable for conventional radiography, because the spectrum of
conventional X-rays is very diverse and can vary in the course of medical-technical progress.
Some examples of indications for an X-ray examination may be:
•For the diagnosis of a bone fracture or bony injuries of the skeletal system or pathological
changes of hard tissues.
•To control the bone setting.
•For the diagnosis of luxations and ligament ruptures of the locomotor system.
•For the diagnosis of degenerative, inflammatory, traumatic and tumorous diseases and
changes of the locomotor system.
•For diagnostic of malformations and malalignments of the skeletal system.
•For the diagnosis of thoracic and pulmonary symptoms (thorax exposures)
•For the diagnosis of sclerotherapy.
•For the diagnosis of inflammatory and expansive processes of the mucosa, cranial bones and
paranasal extension.
•For the diagnosis of the abdomen (e.g. acute abdomen, plain abdominal radiography,
urethrogram, cystogram).

1.5.2 Contra indications
There are no absolute contraindications for conventional X-rays.
But it is not allowed to make any exposures on humans when they are not medically indicated (see
Justification of medical exposures, chapter 1.5.1 Indication).
For pregnant women and children it is important to consider if the exposure is really necessary. It
should be avoided if possible.

diff r nt dir ctions, n ith r yours lf (op rator), th pati nt or any third party
finds th ms lv s in a hazardous position (ar a of mov m nt). R mov all
obj cts ( .g. chairs, pushcarts) from known collision ar as.
B awar that car l ss or improp r adjustm nt of th radiographic syst m

radiographic syst m as w ll as xt rnal obj cts.
2.1.5 Explosion prot ction
These radiographic system is not designated for use within areas with explosive hazards.
2.1.6 Radiation prot ction
X-Ray radiation can pose a hazard to patients and other people when the regulations regarding the
operation of X-Ray systems are not followed.
For this reason, the basic principles of radiation protection are of the highest priority and must be
followed without exception:
•Distanc from th radiation sourc
The dosage is reduced as a factor of the square of the distance from a (dot shaped) radiation source.
Double the distance ¼ dose, triple the distance 1/ dose
•K p th xposur tim as short as possibl
The dosage is directly correlated with the exposure time. A half exposure time results in a radiation
dose half that of a full exposure. (This is especially pertinent with fluoroscopy, as X-Ray images have
predetermined mAs).
•Utiliz shi lding and prot ctiv clothing
The protective value grows exponentially with the thickness of the shielding. Two half-value layer
thickness (HVL) weaken (homogeneous) radiation to ¼, 3 HVL to 1/8, und 10 HVL to less than 1/1000
of the original value.
•Do not r ach into th dir ct X-Ray b am
The dosage in a un-weakened-Ray beam is around 100 times larger than that in the scattered
radiation.
•Us p rsonal dosag m t rs in working with radiation (X-Rays), th us of p rsonal dosag
monitors is sugg st d.
The X-Ray images are principally triggered from behind a protective wall. For the creation of images
near the reproductive organs use the maximum available protection (e.g. testicular shielding or lead
covers)
People that must remain close to the patient are required to wear protective clothing (e.g. lead apron).
This counts for maintenance and installation work as well.
2.1.7 V ntilation
It is important to ensure that the air exchange of the X-Ray generator within the system is not hindered.
The ambient air temperature is not allowed to exceed 40°C.
2.1.8 Int raction with xt rnal d vic s
Unwanted interaction with external devices is not known.

4 Handling / Op ration
4.1 Op ration with th radiographic syst m
4.1.1 Op ration at th X-ray tabl
4.1.1.1 Position of pati nts on th tabl top
• Adjust the height of the tabletop so the patient can mount it easily
• Placing patient on table top and leaving table top
oCenter the tabletop as much as possible (back/front).
oThe patient should take place in the middle of the tabletop and also leave at this
position.
4.1.1.2 S tting th X-ray unit to th mid of movabl Bucky, Grid ntity
•Move the tube column to a position in between the limits of the traveling range of the table Bucky,
Press the button for auto tracking on the touch display (see user manual for PROGNOST B)
•The tube moves to the defined height, the table moves to the defined height and the Bucky travels
to the position where center beam is aligned to Bucky center. The SID is also set to the standard
height and will not be changed.
•Now if you move the tube column the Bucky follows the tube position, as long both are in the
limits of the Bucky travel, otherwise an error message appears on the TOUCH-PC: “Out of tracking
range”. If you move the tube back into the travel range the message disappears and the Bucky
follows again.
4.1.1.3 Ins rting a cass tt into th cass tt tray
•A film cassette may be placed into the cassette tray, when the X-ray tube assembly is positioned
(see item 4.1.1.2).
•Pull out the cassette tray by its handle from the bucky unit until it hits the forward stop.
•The cassette clamps center the cassette transversely within the cassette tray. Rotate its latch
counter clockwise to unlock it.
•Open the cassette clamps far enough to insert a cassette of the desired size.
•At table bucky insert the cassette, with its transverse centerline aligned with the notch in the
cassette clamps or by engaging the cassette positioner in the size of the cassette corresponding
detent (13 cm, 18 cm, 24 cm, 30 cm, 35 cm, 40 cm or 43 cm), push the cartridge to the cassette
positioner.
•Push the cassette clamps against the cassette, and rotate the latch into the locked position.
•Push the cassette tray fully into the bucky unit.
4.1.1.4 Adjusting th sourc to imag -d t ctor distanc (SID)
•Set the X-ray unit with a tape measure at the collimator or the display on the tube to the desired
source to image-detector distance (SID).
•Manual mode: You can adjust the SID by moving the tube column up or down by pressing the
corresponding button on the tube head (Detailed description, see user manual PROGNOST B).
•Auto tracking mode: The SID is fixed by the system. You can only move the table height. The tube
height will follow and the movement stops at the pre-defined SID.
4.1.1.5 Adjusting th light r sp. X-ray fi ld
•Press the collimator light switch (button , figure collimator) to turn on the collimator light, and
view the opening of the collimator shutter in both axes relative to the cassette size scales.
•Several SID scale (adjuster 1 and 7, figure collimator) are provided to indicate the correct settings of
the collimator adjustment controls for the collimator shutters for several cassette sizes so that the
light beam and the X-ray filed can be limited to the desired cassette size in both axes. Adjust
cassette size as required using the collimator adjustment controls. Reduce shutter openings to
objects size for better image quality.
