This section contains important safety information about using your MiniCAT™.
1.1 Safety Guidelines
Although several safety considerations were made in the design, no amount of safety features can
completely eliminate the risk associated with X-ray radiation. Improper use may result in injury.
Emergency Stop:
In the event of an emergency (i.e. any moving component collides with any parts of the equipment,
items in the environment, or that could cause physical injury to the patient), the operator should
utilize the Emergency Stop (E-Stop) button to turn off the power to all moving parts in order for
the patient to be safely removed fromthe machine.
Patient E-Stop
OperatorE-Stop
All persons operating or occupying the area around the scanner must be properly trained on the
principles of radiation safety. The persons authorized to operate the equipment will be properly
trained by Xoran Technologies on the principles of operation. Operators of the equipment must
ascertain the regulatory requirements and the risks associated withthe application of X-ray radiation
to patients.
The use of protective devices, such as radiation barriers and protective aprons, are always
recommended. Consult with a health physicist or other radiation protection expert to determine the

2
MiniCAT™ User Manual v5.2 © 2014 Xoran Technologies LLC
appropriate radiation protection devices and practices.
Radiation Safety
The gantry is self-shielded to an extent. However, no design can guarantee that allX-ray radiation is
shielded. Therefore, we recommend that additional radiation protection devices are utilized when
operating the equipment. A health physicist, or other radiation protection expert, should evaluate the
proposed areas in which the MiniCAT™ will be used to determine the radiation protection
measures that must be taken.
The MiniCAT™ is equipped with an operator control box that allows for the initiation of a scan
while the operator is at a safe distance behind a protective barrier. The operator control box also
contains an emergency stop button to terminate X-ray radiation and all powered motion of the
equipment in the case of an emergency.
Testing or calibration should never be performed while a patient is positioned in or near the scanner.
The operator should utilize the appropriate radiation protection devices while testing or calibrating
the equipment.
No attempt should be made to move, adjust or manipulate the scanner or patient during image
acquisition. This could result in unnecessary radiation exposure, injury to the patient and/or damage
to the equipment.
Caution: This X-ray unit maybe dangerous to patient and operator unless safe
exposure factors and operating instructions are observed. Unauthorized use is
prohibited. Xoran Technologies LLC is released of allresponsibility and
indemnity for injury that may result fromX-ray radiation or the improper use of
the device.
It is the responsibility ofthe user to learn about X-ray radiation health risks and to adopt
and follow proper X-ray radiation safety policies and procedures before operating the

3
MiniCAT™ User Manual v5.2 © 2014 Xoran Technologies LLC
MiniCAT™.
Allfederal and state regulations pertaining to radiation safety must be observed.
Please refer to your state radiation safety regulations for specific requirements about the
safe and proper use ofthe scanner.
Stand behind the operator's barrier when using X-ray.
Lead-shielded aprons and dose monitoring badges may be required.
ALARA
The principle of As Low As Reasonably Achievable (ALARA) has been implemented into the
imaging protocols of the MiniCAT™ and this principle shallbe exercised by the user at all times. In
this way, unnecessary exposure to radiation can be avoided. ALARA principles shall be exercised
by the user at alltimes. Only required personnel should be in the roomwhen the scanner is in use.
Personal Dosimetry
The purpose of a radiation dosimetry program is to measure the radiation dose equivalent from
occupationally exposed radiation workers. You must check with your state radiation safety program
to ascertain your state's specific radiation dosimetry requirements.
X-Ray Warning System
When the MiniCAT™ is in use and X-rays are being emitted, you will see a yellow flashing light
(located on top of the operator's console) complemented with an audible chirping sound. In
addition, it is possible to install external warning lights and/or audible alarms when the X-ray source
is enabled in ready state. Call Xoran Customer Service to learn more about these options if
required in your area.
Door Interlock System
The MiniCAT™ is equipped with provisions for an optional door interlock circuit. This type of
circuit shuts offpower to the X-ray source whenthe door is opened. Call Xoran Customer Service
to learn more about these options ifrequired in your area.
Extension Cords / Cables:

4
MiniCAT™ User Manual v5.2 © 2014 Xoran Technologies LLC
Do not use any extension cords which have not been provided with the MiniCAT™. Use only the
interface cables provided with the MiniCAT™. Do not alter the cabling configuration.
Additional Software and Accessories:
Do not connect any items or equipment to the MiniCAT™ which are not part ofthe systemor install
any additionalsoftware. Either of these actions can cause the systemto malfunction and will result in
voiding your warranty.
Disposal
Follow localregulations ondisposalof waste parts. The X-ray source assembly, image sensor and
allelectronic circuits should be regarded as non-environmentalfriendlywaste product and should be
disposed of in such a way as to minimize the hazard to the health of personnel and the value of
property and the community.
Instructions, Training, Use
The MiniCAT™ shallbe used, supervised or directed by an individual who is competently aware of
the potentialhazards involved fromionizing radiation and who is capable ofminimizing these hazards.
Xoran provides comprehensive training and support for MiniCAT™ users. Xoran accepts no
responsibility for the misuse of a MiniCAT™. The user is responsible for compliance with their
state's regulation for owning and operating a CT scanner.
Note: Health Canada does not permit the use ofthe MiniCAT CT scanner for imaging pregnant or
pediatric patients.
Note: The best practice is to consult with a qualified medical physicist to ensure safety and
compliance. Feelfree to contact Xoran Customer Service for assistance in locating an appropriate
medicalphysics professionalin your area. 1-800-70-XORAN (800-709-6726)
