Book excerpt: The field of anatomy systems elements and diagnosis has been revolutionized by new techniques in powerful computations, image processing, and modalities such as computer-aided tomography (CAT) and magnetic resonance, among others. It is therefore an appropriate topic to be included in this series that studies the marriage of computer capabilities and medical imaging, which exemplifies a significant manifestation of relatively recent, valuable technologies known as the second industrial revolution. A few of the issues studied in this book are boundary detection and the applications of image segmentation; functional imaging; the registration of scans of patients undergoing cranio-maxillo-facial surgery; image processing techniques for the noninvasive alternative to needle biopsy for patients with liver disease; knowledge-based diagnosis support for mammogram image analysis; and input function monitors, necessary to quantify physiologic function. This book clearly reveals the effectivene

Download or read book Novel Denoising Methods for Dynamic Positron Emission Tomography written by and published by . This book was released on 2012 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Positron emission tomography (PET) provides inherently quantitative information about physiological and molecular processes, endowing it with great clinical and research potential. This is particularly true of dynamic PET imaging. Unfortunately, PET, and especially dynamic PET, suffers from unfavorable noise properties, limiting it diagnostically and quantitatively. Denoising methods that improve image quality and thus increase diagnostic accuracy and improve estimates of quantitative parameters could be of great benefit, particularly if they are simple, accurate, and easily implemented on a wide range of PET tracer studies. The aim of this thesis is to develop and evaluate two novel denoising methods for dynamic PET imaging: HighlY constrained back-Projection-Local Reconstruction (HYPR-LR), which has recently been applied to dynamic PET data with promising results, and spatio-temporal expectation maximization (STEM) filtering, a newly developed 4-dimensional iterative filtering process. An implementation of HYPR-LR is presented that provides the maximum amount of noise reduction that is possible without introducing any significant bias. This is accomplished using multiple time-dependent temporally summed composite images that account for the kinetics of the tracer being studied. The potential of HYPR-LR to improve dynamic PET imaging is demonstrated using phantom, simulated, and human data, with a focus on quantitative parametric images. The newly proposed STEM filtering combines two well established image processing techniques: 4-dimensional Gaussian smoothing followed by EM deconvolution. In principle, this approach should provide substantial reductions in noise while introducing little bias. STEM filtering is also evaluated using phantom, simulated, and human data, with a focus on parametric images. The potential of HYPR-LR and STEM filtering to improve PET imaging of [I-124] labeled agents is also studied. [I-124] could be a valuable radionuclide for PET imaging, but its use is often limited by noise because of dosimetry concerns and relatively few decays by positron emission. Finally, the impact of a more traditional means of controlling image noise at the cost of bias, varying the number of iterations performed during EM reconstruction, on the diagnosis of temporal lobe epilepsy is studied. This also serves as an illustration of how HYPR-LR and STEM filtering might be evaluated in a clinical context.
Download or read book Statistical Methods for Dynamic Positron Emission Tomography written by Mustafa Kamasak and published by LAP Lambert Academic Publishing. This book was released on 2010-06 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dynamic positron emission tomography (PET) is used for time response analysis of tracers injected into the patients. Physiological parameters are estimated from the time response which may reveal useful information for diagnosis of diseases. Statistical techniques are developed to estimate these physiological parameters from the reconstructed PET data. Typically, measured dynamic PET data is reconstructed into image frames and physiological parameters are estimated from these recontructed image frames. This dissertation introduces a new technique to merge the recontruction and estimation into a single process. Proposed algorithm is called direct reconstruction of physiological parameters. This method performs better than classical two-step algorithms.

Download or read book Formation of Parametric Images in Positron Emission Tomography Using a Clustering Based Kinetic Analysis With Statistical Clustering written by and published by . This book was released on 2001 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: A method is proposed for forming parametric images in position emission tomography, using clustering kinetic analysis. To overcome the dual problems experienced in voxel-based data, of signal noise and the very long computational time, the data are clustered before parameter estimation, and then estimation procedure is applied to the averaged data in each cluster. Using this algorithm, PET data are optimally clustered, depending on the noise that is present, by hierarchically applying a statistical-clustering algorithm based on Mixed Gaussian model. In a computer simulation, the proposed method correctly clustered noise-contaminated data. Applying the proposed algorithm to (18)F-FDG clinical data, physiologically acceptable parametric images of glucose metabolism in a brain were obtained in a practical calculation time.

Available in PDF, EPUB and Kindle. Book excerpt: ABSTRACT: Positron emission tomography (or PET) has been utilized for years in medical diagnosis. The PET reconstruction problem consists of recovering the image from the data gathered by the detectors in the machine. Penalized maximum likelihood techniques allow for the recovery of the image with a smoothing term to improve the image. Previous methods using this technique forced the use of a weak penalty term in order to gain convergence. Using a new method, this restriction is removed while retaining convergence. In addition, the method is extended to the problem of recovering multiple PET images along with a vector describing the motion between the images.
