Area of Science:

  • Medical Imaging
  • Nuclear Medicine

Background:

  • Positron Emission Tomography (PET) scanners require standardized performance evaluations.
  • Existing performance metrics lack uniformity across different manufacturers and institutions.

Framework:

  • Proposes a comprehensive set of standardized performance measurements for PET scanners.
  • Developed collaboratively by the Society of Nuclear Medicine's Computer and Instrumentation Council and the National Electrical Manufacturers Association.

Implementation:

  • Includes tests for spatial resolution, scatter fraction, and sensitivity.
  • Covers count rate performance (losses, randoms, linearity correction), and image quality (uniformity, scatter correction, attenuation correction).

Implications:
