AAPM Task Group Report 238: 3D C-arms with volumetric imaging capability

Area of Science:

• Medical Imaging Physics
• Radiological Technology
• Quality Assurance in Medical Imaging

Background:

• C-arm Cone Beam Computed Tomography (CBCT) systems are increasingly used for volumetric imaging.
• Quality control (QC) is essential for ensuring the reliable performance of these advanced imaging systems.
• Existing QC protocols for C-arm fluoroscopy provide a foundation, but C-arm CBCT requires specific considerations for 3D imaging.

Conclusions:

• The described methodologies aid medical physicists in determining system performance and identifying the need for calibration.
• Consistent data collection on image quality and radiation dose supports the development of performance criteria and standards.
• Proactive assessment using established QC procedures ensures optimal C-arm CBCT system operation and clinical reliability.
