  • Hermia SPECT Reconstruction


    The quality of SPECT imaging is reduced by photon attenuation, resolution loss due to collimator-detector blur, photon scatter, and noise. All these factors limit both the visual quality and quantitative power of SPECT images. Hermia SPECT Reconstruction provides methods to compensate for the effects of the aforementioned four factors by modelling them in iterative reconstruction.

  • Advanced Bone SPECT Reconstruction in Hermia

    With easy-to-use software enabling precise determination of reconstruction parameters, we are proud to offer several Bayesian reconstruction algorithms to optimise your bone SPECT/CT images, including two algorithms leveraging the information from the CT to guide the SPECT reconstruction, namely AMAP-Smooth and AMAP-RDP. AMAP-RDP showed superior performance to all other tested reconstruction algorithms in the study by Kangasmaa et. al. (1)
