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)
• Scatter correction based on window subtraction technique
• 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
