Partial Volume Correction Strategies in PET.
In the early days of PET, the partial volume effect (PVE) was identified as a serious factor affecting image quality and limiting the accuracy of quantitative analysis. Because of the limited spatial resolution of clinical PET systems, the images are blurred by the system response so that smaller objects appear larger. Although the total number of counts is preserved, they are distributed over ...
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...
متن کاملA Partial Volume Effect Correction Tailored for 18F-FDG-PET Oncological Studies
We have developed, optimized, and validated a method for partial volume effect (PVE) correction of oncological lesions in positron emission tomography (PET) clinical studies, based on recovery coefficients (RC) and on PET measurements of lesion-to-background ratio (L/B m) and of lesion metabolic volume. An operator-independent technique, based on an optimised threshold of the maximum lesion upt...
متن کاملFDG PET/CT in Oncology
The escalating costs of conventional diagnostic technology in oncology have yet to obviate futile surgery intervention and the spiralling treatment cost. The evolution in engineering technology which looks at the correlation of the anatomy and the function of tumours i.e. Positron Emission Tomography-Computed Tomography (PET-CT) have impacted on the improved diagnostic accuracy and treatment in...
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...
