The following information is provided as guidance:

Diagnostic Machines

Health Physics annually performs x-ray machine compliance tests on medical diagnostic machines to assure compliance with applicable rules and regulations. Records of these compliance tests and any findings are kept at Health Physics. Compliance test copies are also forwarded to Radiology.

The department responsible for the unit performs weekly fluoroscopy phantom checks to confirm tube current and potential as required by CCR Title 17.

CT Scanners

Daily and monthly CT testing shall be performed by the department responsible for the CT scanners. The testing procedures are based on American College of Radiology (ACR) CT Quality Control Manual.

The Joint Commission and the State of California Health and Safety Code sections (115111, 115112, and 115113) requires CT compliance in a variety of aspects. Hospital and department should work with Health Physics to ensure the compliance of State law and TJC requirements.

Mammography Machines

Mammography machine annual tests are performed by an outside contractor. Health Physics acts as a point of contact for this contractor. Records of these compliance tests are provided to the mammography supervisor/department.

Therapy Machines

Beam calibrations are performed by a Radiation Oncology Medical Physicist before initial operation and at intervals not to exceed twenty-four months. A radiation protection survey must be performed on all new and existing installations not previously surveyed, and spot checks must be performed at least once each week for therapy systems. Annual safety compliance tests are performed by Health Physics. Records of these calibrations, spot checks, and surveys are maintained by Radiation Oncology – Radiation Physics and audited annually by Health Physics.
