The IAEA Nuclear Medicine Quality Control (NMQC) Toolkit is a set of ImageJ (Fiji edition)-based codes developed in Java v.1.8 that allow the processing and analysis of nuclear medicine images acquired for quality control tests of gamma cameras and SPECT systems.

Proper quality control (QC) procedures in single-photon emission computed tomography (SPECT) play an essential role in ensuring optimized performance of imaging equipment, and are a requisite for providing high quality clinical care. Since QC procedures are implemented routinely, streamlining them with automated software may offer several benefits: improved speed, reduced errors, and the standardization of calculation methods across centres.

The IAEA-NMQC Toolkit has been developed to support common SPECT QC data analysis procedures for several QC tests. The plugins included in the IAEA-NMQC Toolkit are designed to be easy to use and allow the automatic or semi-automatic analysis of the following tests:

  • Planar uniformity;
  • Maximum count rate;
  • Sensitivity;
  • Intrinsic spatial resolution;
  • Intrinsic spatial linearity;
  • System spatial resolution;
  • Pixel size;
  • 4 quadrant bar phantom;
  • Centre of rotation;
  • Tomographic contrast;
  • Tomographic resolution;
  • Tomographic uniformity
