    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 with the application of X-ray radiation to patients.
  • Page 5 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.
  • Page 6 The principle of As Low As Reasonably Achievable (ALARA) has been implemented into the imaging protocols of the MiniCAT™ and this principle shall be 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 all times.

  • Page 114: Quality Control Tests

    Xoran provides a quality control phantom to use for these quality control tests. Xoran has developed these procedures to scan only the sinuses and temporal bones, which are high- contrast or ‘bone window’ imaging tasks that require isotropic high spatial resolution and do not require the level of contrast resolution needed for other imaging tasks, such as brain or muscle tissue scanning, etc.
