# 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.
