NEMA publishes revised industry standard for measuring PET scanner performance

The National Electrical Manufacturers Association (NEMA) announced Friday, July 13, the publication of a revised standard that provides guidelines for measuring and reporting the performance of PET scanners.

“NU 2 makes it possible to objectively compare scanners during the purchasing decision process, and, after delivery, defines tests to ensure that a quality system has been delivered,” Michael Miller, chair of the Medical Imaging & Technology Alliance NU 2 Work Group, said in a prepared statement.

The standard, NEMA NU 2-2018: Performance Measurements of Positron Emission Tomographs (PET), includes two new tests:

  • A measurement of time-of-flight (TOF) resolution for TOF-equipped PET scanners
  • The co-registration accuracy between the CT and PET components of a hybrid PET/CT scanner
