PY - Y1 - N2 - Acquiring both anatomical and functional images during one scan, PET/CT systems improve the ability to distinguish pathology from normal uptake and to precisely localize abnormal by: 6. mathematical modeling of an image reconstruction problem. The following statements and results are mainly based on [24], [8] and [18]. Positron Emission Tomography Positron Emission Tomography is an imaging method in nuclear medicine based on the use of a weak radioactively marked pharmaceutical in order to image certain fea-File Size: 2MB. In this book, multidisciplinary specialists explain the foundations and principles of tomographic imaging and describe a broad range of applications. 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 .

Abstract Image reconstruction from projection is the field that lays the foundation for Medical Imaging or Medical Image Processing. The rapid and proceeding progress in medical image reconstruction, and the related developments in analysis methods and computer-aided diagnosis, has promoted medical imaging into one of the most important sub-fields in scientific : Shailendra Tiwari, Rajeev Srivastava. Combined and optimized Positron Emission Tomography and Computed Tomography (PET-CT) exams are among the more complex of the radiographic modalities utilized in both body oncology and neurology settings. A distinct and targeted workflow is essential to successful data acquisition, processing, and related image management and reporting [1, 2 Author: Todd Faasse. Abstract.
