Positron emission tomography partial volume correction: estimation and algorithms.
Partial volume effects in positron emission tomography (PET) lead to quantitative under- and over-estimations of the regional concentrations of radioactivity in reconstructed images and corresponding errors in derived functional or parametric images. The limited resolution of PET leads to "tissue-fraction" effects, reflecting underlying tissue heterogeneity, and "spillover" effects between regi...
متن کاملEvaluation of partial volume effect correction methods for brain positron emission tomography: Quantification and reproducibility
Quantitative accuracy of positron emission tomography (PET) is decreased by the partial volume effect (PVE). The PVE correction (PVC) methods proposed by Alfano et al., Rousset et al., Müller-Gärtner et al. and Meltzer et al. were evaluated in the present study to obtain guidelines for selecting among them. For accuracy evaluation, the Hoffman brain phantom was scanned with three PETs of differ...
متن کاملRespiratory motion correction in prostate cancer positron emission tomography: A study on patients and phantom simulation
Introduction: To investigate the effects of breathing cycle and tree diaphragm motions on prostate cancer tumors standard uptake value (SUV) during positron emission tomography (PET) and to correct it. Materials and methods: Respiratory motion traces were simulated on the common patient breathing cycle and tree diaphragm motio...
متن کاملA Generalized Methodology For Partial Volume Correction In Emission Tomography
We describe a generic methodology to correct 3-D partial volume effects in clinical emission scans. It is based on prior knowledge of tracer biodistribution and tomographic imaging characteristics. We derive this information from registered and segmented MR/CT data. Two fast numerical algorithms are then used to estimate structure-specific recovery coefficients and activity spillover contributi...
متن کاملRespiratory Motion Correction in Positron Emission Tomography
In this thesis, we develop a motion correction method to overcome the degradation of image quality introduced by respiratory motion in positron emission tomography (PET), so that diagnostic performance for lung cancer can be improved. Lung cancer is currently the most common cause of cancer death both in the UK and in the world. PET/CT, which is a combination of PET and CT, providing clinicians...
