PET/CT

The PET/CT protocols are a set of clinical applications for review and analysis of PET/CT studies. Separate applications are provided for Oncology, Neurology and Cardiology, each with optimized settings for scaling, color and layouts. Up to 4 PET/CT scans can be loaded simultaneously for comparison purposes.

Features include:

  • Standardized orthogonal slice displays
  • Accurate SUV computation for all vendors and models
  • Display functions: triangulation, window leveling, color-scale selection, slice alignment, cine controls, zoom, pan, magnify, colorize
  • Measurement tool

  • User-definable CT window presets
  • Distance-weighted Maximum Intensity Projections (MIP)
  • Fusion display mode based on variable alpha blending and/or variable thresholding
  • Manual registration adjustment (translations, rotations)
  • Automatic registrations using fast mutual information algorithm
  • Tumor-tracking analysis using auto 3D lesion contouring
  • Export of RT Struct Files

  • Customized layouts through display scripts

SPECT/MR

SISCOM is one of our SPECT/MR neuroimaging application used in the diagnosis for Epilepsy. Please review our neurology portfolio for more details on this application.

Hybrid Reconstruction

The Hybrid Reconstruction protocol is an advanced application for the iterative reconstruction of SPECT data with CTAC attenuation correction (separately acquired CT scan).

Features include:

  • Fast 3D OSEM implementation (GPU assisted)
  • Gaussian and other post filter options
  • User definable #subsets and #iterations
  • Fanbeam support
  • Resolution recovery (collimator de-blurring)

  • Attenuation correction using CT (hybrid or external)
  • Integration registration of emission to CT
  • Reorientation and masking of reconstructed volumes

MIRegister

The MIRegister protocol is an advanced application for automatic registration of tomography data using Mutual Information technique.

Features include:

  • Voxel intensity based algorithm (mutual information)
  • No need for anatomical landmarks
  • Applicable to any combination of PT, NM, CT and MR
  • Option to adjust field of view for registration
  • Linked series follow automatically (i.e.: register PT of PT/CT to MR and CT follows)
  • GPU assisted for fast performance
  • Save new pixel data or save transformation matrix
  • Selectable degrees of freedom (3,6,9, 12)
  • Applicable to any organ
