NMToolKit Analysis

NMToolKit Analysis supports NEMA acceptance testing protocols and routine SPECT Gamma Camera QC.

NEMA processing tools;

  • Intrinsic spatial resolution and intrinsic spatial linearity
  • Multiple window spatial registration
  • System spatial resolution with and without scatter
  • SPECT reconstructed spatial resolution without scatter
  • SPECT reconstructed spatial resolution with scatter
  • Flood field uniformity
  • System planar sensitivity

SPECT QC processing tools;

Deluxe Jaszczak phantom (Data Spectrum, Durham, NC);

  • Reconstructed image uniformity
  • Contrast - solid spheres

Ectphan™ (The Phantom Laboratory, Salem, NY);

  • Slice thickness, slice incrementation, pixel size, spatial resolution – point spread function (PSF), reconstructed image uniformity
  • NEMA SPECT reconstructed spatial resolution with scatter (3 line or point source inserts)


  • Results available in PDF format
  • Database for all results
  • Export database to csv file format
  • Camera summary reports from database
