Compression of Dynamic PET Based on Principal Component Analysis and JPEG 2000 in Sinogram Domain
A new algorithm for the compression of dynamic positron emission tomography (PET) data is presented. It consists of a temporal compression stage based on the application of principal component analysis (PCA) directly to the PET sinograms to reduce the dimensionality of the data. This is followed by a spatial compression stage using JPEG 2000 to each PCA channel weighted by the signal in each ch...
متن کاملSegmentation of dynamic PET images with kinetic spectral clustering.
Segmentation is often required for the analysis of dynamic positron emission tomography (PET) images. However, noise and low spatial resolution make it a difficult task and several supervised and unsupervised methods have been proposed in the literature to perform the segmentation based on semi-automatic clustering of the time activity curves of voxels. In this paper we propose a new method bas...
متن کاملDeep reconstruction model for dynamic PET images
Accurate and robust tomographic reconstruction from dynamic positron emission tomography (PET) acquired data is a difficult problem. Conventional methods, such as the maximum likelihood expectation maximization (MLEM) algorithm for reconstructing the activity distribution-based on individual frames, may lead to inaccurate results due to the checkerboard effect and limitation of photon counts. I...
متن کاملSpatio-temporal diffusion of dynamic PET images.
Positron emission tomography (PET) images are corrupted by noise. This is especially true in dynamic PET imaging where short frames are required to capture the peak of activity concentration after the radiotracer injection. High noise results in a possible bias in quantification, as the compartmental models used to estimate the kinetic parameters are sensitive to noise. This paper describes a n...
متن کاملSinogram Denoising of Cryo-Electron Microscopy Images
Cryo-electron microscopy has recently been recognized as a useful alternative to obtain three-dimensional density maps of macromolecular complexes, especially when crystallography and NMR techniques fail. The three-dimensional model is constructed from large collections of cryo-electron microscopy images of identical particles in random (and unknown) orientations. The major problem with cryo-el...
