Model calculations with raw PET data (sinograms)

Analysis methods for PET sinograms

Currently only few applications exist:

• Logan plot to produce DV or DVR sinogram (sensitive to noise, smoothing recommended)
• Sum sinogram frames, reconstruct an image, and use it to calculate parametric blood flow image using in vivo autoradiograhical methods
• Use the PatPar program (applying Gjedde-Patlak plot) on SUN to calculate parametric sinogram, which can be reconstructed to a K_i image; current version requires that a 3-exp function is fitted to the plasma curve.
