SPECT reconstruction and quantification

Improved image quality and unified SUV results

Boost your SPECT-CT scanners

Leveraging the full potential of SPECT

Using software and hardware techniques, Hermia's SPECT reconstruction is optimized for speed and a wide range of procedures, radio-pharmaceuticals and collimators, making it possible to improve image quality while reducing dose and acquisition time for virtually any camera manufacturer.

  • SUV for all radionuclides and all SPECT cameras

    Ga-68; Ho-166; l-123; l-131; ln-111; Kr-81m; Lu-177; Tc-99m; TI-201; Y-90

  • Fastest reconstruction on the market

    Thanks to the GPU computing capabilties, Hermia is able to reconstruct SPECT up to 24 times faster than multi-threaded CPU implementation (5)

  • Full collimator modelling

    Advanced resolution recovery achieves excellent image quality for the most difficult radionuclides like l-131; l-123; Y-90; Ho-166 (6)

  • Accurate planar reprojection

    Generate accurate planar images from the reconstructed SPECT

Hermia SPECT Reconstruction

”We have leveraged this technology to reduce our injected activities while maintaining diagnostic image quality - even with older imaging equipment.”

- Ran Klein, PhD, The Ottawa Hospital


The advanced reconstruction algorithms from Hermia SUV SPECT® enable conversion of the recorded counts per voxel into activity per unit volume with SUV calculations, providing essential and accurate quantitative results. Numerous clinical and technical validation publications support the accuracy and reliability of the software (1-4).

Hermia's complete reconstruction package include tools for quality control, motion correction, collimator response, attenuation and scatter correction, attenuation map registration, and post-filtering. Ready for SPECT-MR, SPECT-CT, SPECT Reconstruction and SPECT Quantification.
