The content is organized in five parts, which are dedicated to image reconstruction, microtomography, industrial tomography, morphological medical tomography and functional medical tomography. Positron emission tomography (PET) is one of the key molecular imaging modalities in medicine and biology. Penalized iterative image reconstruction algorithms frequently used in PET are based on maximum-likelihood (ML) and maximum a posterior (MAP) estimation techniques. The ML algorithm produces noisy artifacts whereas the MAP algorithm eliminates noisy artifacts by utilizing available .

Emission Tomography: The Fundamentals of PET and SPECT explains the physics and engineering principles of these important functional-imaging methods. The technology of emission tomography is covered in detail, including historical origins, scientific and mathematical foundations, imaging systems and their components, image reconstruction and.

The history of positron emission tomography (PET) can be traced to the early s, when the medical imaging possibilities of a particular class of radioactive substances were first realized. It was recognized then that the high-energy photons produced by the annihilation of the positron-emitting isotopes could be used to describe, in three dimensions, the physiological distribution of "tagged.

The applications in X-ray CT, SPECT (single photon emission computed tomography), PET (positron emission tomography), and MRI (magnetic resonance imaging) are discussed. Contemporary research results in exact region-of-interest (ROI) reconstruction with truncated projections, Katsevich's cone-beam filtered backprojection algorithm, and Cited by: 3.

Positron emission tomography (PET) is a nuclear medicine functional imaging technique that is used to observe metabolic processes in the body as an aid to the diagnosis of disease.

The system detects pairs of gamma rays emitted indirectly by a positron-emitting radioligand, most commonly fluorine, which is introduced into the body on a biologically active molecule called a radioactive : Image reconstruction for hard field tomography is a continuously developing field.

While the basic mathematics of the Radon transformation and its inverse in two or more dimensions is a solved problem, the practical aspects of image reconstruction of noisy, corrupted, or limited tomographic data is a major driver for current developments.

Overview. Image reconstruction methods are central to many of the new applications of medical imaging. This course will provide an introduction these techniques in a consistent framework by developing a sequence of software tools for the reconstruction of medical imaging data.

This book is written for engineers and researchers in the field of biomedical engineering specializing in medical imaging and image processing with image reconstruction. Gengsheng Lawrence Zeng is an expert in the development of medical image reconstruction algorithms and is a professor at the Department of Radiology, University of Utah, Salt.

Synopsis of image reconstruction This book treats image reconstruction as an inverse problem of the following form. We are given a finite-length measurement vector y, from which we want to recover a function f that describes some property of an object. For example, in emission tomography, f represents the 3D spatial distribution of a File Size: KB.

For example, before exiting the patient, many of the g-ray photons experience photoelectric interactions that cause absorption of photons, and many thus experience Compton scattering, which changes the direction and energy of the original conventional reconstruction techniques (e.g., x-ray CT algorithms) are used in SPECT, the reconstructed images.
