Chapter 1 Overview
1.1 Main Features
The equipment uses high frequency and high voltage technology with standard 200V
power supply and delivered to tube assembly after having been inverted through inverter.
The X-ray is generated from X-ray assembly. And because of different issues in the
patient absorb X-rays in different amounts, transmitted (X-rays which have passed
through the patient) X-rays will have different attenuation when it passing through patient
body. Transmitted X-rays will be converted by image intensifier and acquired by CCD
camera, then the X-ray signal will be converted into video signal and transferred to
central control unit for display or viewing
Compared with low frequency machine, this equipment has the features of more
stable X-ray hardness and intensity, less soft X-ray component, and higher X-ray
generation efficiency. Therefore, it produces better image quality but results in lower
absorbed dose for skin. C-arm & Frame is designed on ergonomics to greatly facilitate
the operation and positioning by operator, resulting in safe and precise positioning for
patient. The TV system of the image intensifier supports last image hold, direct connect,
horizontal flip, vertical flip, and edge enhancement for the image.
1.2 Main Components
The system comprises C-arm&Frame, control cabinet, combined tube, image
intensifier and TV system (workstation, monitor and TV System handcar).

Mobile C-arm X-ray System User Manual
3.3 Maximum permissible dose (MPD)
Before operation, persons qualified and authorized to operate this equipment should be
familiar with the Recommendations of the International Commission on Radiological
Protection, contained in Annals Number 60 of the ICRP, with applicable National
Standards; and should have been trained in use of this equipment. To ensure the safety
of operators, please observe the legal, relevant and internal provisions and technical
requirements for labor protection and accident prevention
Warning: The operator shall use the largest possible focal spot to skin distance order to
keep the absorbed dose as low as reasonably achievable.
3.4 Radiation protection
Because exposure to X-ray radiation can be damaging to the health, use great care
to ensure protection against exposure to the primary beam. Some of the effects of X-ray
radiation are cumulative and may extend over a period of months 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 and intensity of the primary
beam and the atomic number of the object material struck by the primary beam.
Secondary radiation may be of greater intensity than that of the radiation reaching the
film. Take protective measures to safeguard against this.
Filtration of X-ray tube assembly
The total filtration of the tube is 2mmAl equivalent, with the extra 1mmAI equivalent
on the interface of the collimator.
Position of reference axis and the focal spot to the image reception plane
distance
13
Mobile C-arm X-ray System User Manual
The reference axis of the X-ray field is perpendicular to the image reception plane,
and the distance from the focal spot to the image reception plane is 1000 mm.
Focal spot to skin distance
To reduce the absorbed dose of a patient to a level as low as reasonably achievable,
the operator shall ensure that the focal spot to skin distance be as wide as practically
possible.
X-ray beam attenuation
If the system works with a bed, it is recommended that the bed board adopt carbon
board to avoid the excessive attenuation of the X-ray beam caused by the material
fiber
between the patient and the image reception plane.
Lead protection
An effective protective measure is the use of lead shielding. To minimize dangerous
exposure, use such items as lead screens, lead impregnated gloves, aprons, thyroid
collars, etc. Lead screens should contain a minimum of 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. For confirmation of the local requirements at your site, please refer to
your “Local Radiation Protection Rules” as provided by your Radiation Protection
Advisor.
Warning: While operating or servicing X-ray equipment, always keep a distance of not
less than 2 meters from the focal spot and X-ray beam, protect body and do not expose
hands, wrists, arms or other parts of the body to the primary beam.
3.5 Monitoring of personnel
Monitoring personnel to determine the amount of radiation to which they have been
14
Mobile C-arm X-ray System User Manual
exposed provides a valuable cross check to determine whether or not safety measures
are adequate. It may reveal inadequate or improper radiation protection practices and
potentially serious radiation exposure situations.
The most effective method of determining whether or not the existing protective
measures are adequate is the use of instruments to measure the exposure. These
measurements should be taken at all locations where the operator, or any portion of the
body may be exposed. Exposure must never exceed the accepted tolerable dose.
A frequently used, but less accurate, method of determining the amount of exposure is
the placement of film at strategic locations. After a specified period of time, develop the
film to determine the amount of radiation.
A common method of determining whether personnel have been exposed to excessive
radiation is the use of personal radiation dosimeters. These consist of X-ray sensitive film
or thermoluminescent material enclosed within a holder that may be worn on the body.
Even though this device only measures the radiation which reaches the area of the body
on which they are worn, they do provide a reasonable indication of the amount of
radiation received.
3.6 Protection against electric shock hazards
This X-ray Unit has been classified as a type-B ( ) device in accordance with IEC
60601-1.
The test and commissioning must be performed in an easily accessible place without

Chapter 4 Installation and debugging
4.1 Field Requirements
Field area should not be less than 50 ㎡ in principle. The room, with the narrowest
location not less than 4m, should be divided into operating room and control room, and
lead protective measures should be accordance with local requirement. For this
equipment is a mobile Unit, the ground should be leveled without doorsill at the joint
between rooms to facilitate free access of the equipment through the door with a width of
90cm.
The power supply required by the overall system is single phase AC with frequency
of 50Hz±1Hz, capacity no less than 3.5kW. Ask for 16A three-core inlet, rated voltage of
220V±10% and source resistance not higher than 0.6Ω. The power supply should be
grounded securely with earth resistance not higher than 4Ω.
If the power level is at 220V with no X-Ray emission and drops more than 3V (for
example, if Tube V/A at 70KV/3mA) with X-Ray emission, this indicates that the power
source doesn’t supply sufficient power and a 5kW or above AC voltage stabilizer needs to
be installed (should be equipped with a reliable brand).
Supply the equipment with an independent power source is mandatory since shared
power source might cause severe electromagnetic interferences impacting normal
performance of the X-Ray equipment.
