Region-Based Partial Volume Correction Techniques for PET Imaging: Sinogram Implementation and Robustness
Background/Purpose. Limited spatial resolution of positron emission tomography (PET) requires partial volume correction (PVC). Region-based PVC methods are based on geometric transfer matrix implemented either in image-space (GTM) or sinogram-space (GTMo), both with similar performance. Although GTMo is slower, it more closely simulates the 3D PET image acquisition, accounts for local variation...
متن کاملCorrection of partial-volume effect for PET striatal imaging: fast implementation and study of robustness.
UNLABELLED PET imaging of D(2) receptors or (18)F-L-dopa metabolism are reference protocols to follow and study neurodegenerative diseases, but the accuracy of striatal PET imaging is limited by the partial-volume effect (PVE). For such studies, the geometric transfer matrix (GTM) method has been proposed to correct the regional mean values for PVE and is now widely used. METHODS The GTM meth...
متن کاملStatistical Based PET Partial Volume Correction
The partial volume effect in Positron Emission Tomography (PET) is a problem for quantitative radiotracer studies. This effect results from the limited spatial resolution of the imaging device (a few mm’s). Two factors are involved; the spillover of radioactivity into neighbouring regions and the underlying tissue inhomogeneity of the particular region. Linear methods are currently used to corr...
متن کاملPartial Volume Correction in PET/CT
In this thesis, a two-dimensional pixel-wise deconvolution method for partial volume correction (PVC) for combined Positron Emission Tomography and Computer Tomography (PET/CT) imaging has been developed. The method is based on Van Cittert's deconvolution algorithm and includes a noise reduction method based on adaptive smoothing and median filters. Furthermore, a technique to take into account...
