With a foundation of clinically validated algorithms developed at the University of Michigan, Corridor4DM provides advanced nuclear cardiology quantification and image displays. As a comprehensive tool for physicians and technologists, its integrated workflow is available in a single, configurable application. Available for use with SPECT, PET, and SPECT/CT cameras, 4DM is used by medical professionals world-wide to manage their clinical workflow.


Corridor4DM aids physicians and technologists by providing:

  • Quantification, review, and reporting for nuclear cardiology imaging performed with SPECT, PET, and SPECT/CT cameras.
  • Accurate interpretation of myocardial perfusion and function in a single, comprehensive environment
    • Quality assurance measures to identify motion, artifacts, or other volumetric variances which may impact quantification results
    • Review the perfusion and function of the left ventricle and verify quantification results
    • Fuse CT and NM datasets and review CT acquisitions for any incidental findings
    • Conduct final study interpretation and report findings
  • Compare patient studies to a similar patient population with a low likelihood of cardiac disease (including one day, two day, Thallium, dual isotope, FDG Viability)
  • Review a variety of diagnostic images, including: 2D multi-slice images and polar maps; 3D representations of the LV; and four-dimensional (4D) displays of beating SA and 3D cines for gated datasetsReport clinical findings using either the 4DM integrated report generator which integrates findings in pre-defined or custom reporting templates; or use the 4DM Export feature to collect data for other applications
