    Local Tomography and the Jordan Structure of Quantum Theory.Howard Barnum & Alexander Wilce - 2014 - Foundations of Physics 44 (2):192-212.
    Using a result of H. Hanche-Olsen, we show that (subject to fairly natural constraints on what constitutes a system, and on what constitutes a composite system), orthodox finite-dimensional complex quantum mechanics with superselection rules is the only non-signaling probabilistic theory in which (i) individual systems are Jordan algebras (equivalently, their cones of unnormalized states are homogeneous and self-dual), (ii) composites are locally tomographic (meaning that states are determined by the joint probabilities they assign to measurement outcomes on the component systems) (...)

    Generalized Orthogonality Relations and SU(1,1)-Quantum Tomography.C. Carmeli, G. Cassinelli & F. Zizzi - 2009 - Foundations of Physics 39 (6):521-549.
    We present a mathematically precise derivation of some generalized orthogonality relations for the discrete series representations of SU(1,1). These orthogonality relations are applied to derive tomographical reconstruction formulas. Their physical interpretation is also discussed.

    Informed Consent in Computed Tomography: A Case for Standardization.Casey Rentmeester - 2019 - Radiologic Technology 90 (3):300-306.
    Informed consent has become the most obvious instantiation of patient autonomy in contemporary medicine, though as a practice it does not encompass all spheres of medicine. While diagnostic radiological procedures carry some risk due to the use of radiation, there is no standardized practice of informed consent in the United States. The authors describe the ethical justification of informed consent, the legal background surrounding it, and a brief history of radiology and radiological protection. They ultimately argue that informed consent should (...)

    Upscaling Lithology and Porosity-Type Fractions From the Micro- to the Core-Scale with Thin-Section Petrography, Dual-Energy Computed Tomography, and Rock Typing: Creation of Diagenesis and Porosity-Type Logs.Jacob M. Proctor, André W. Droxler, Naum Derzhi, Heath H. Hopson, Paul Harris, Pankaj Khanna & Daniel J. Lehrmann - 2019 - Interpretation 7 (1):B9-B32.
    We have developed and validated a new approach to upscale lithology and porosity-type fractions from thin sections to cores using dual energy and multiscale computed tomography. A new rock-typing approach is proposed to upscale ⇋diagenetic mineral and diagenetic pore-type fractions, from thin sections to the core domain, eventually to create a diagenesis and porosity types logs. An extensive set of short cores from Mason County provides a representative sample set of Late Cambrian microbial buildups and their interbuildup sediments to (...)

    ‘Sehkollektiv’: Sight Styles in Diagnostic Computed Tomography[REVIEW]Kathrin Friedrich - 2010 - Medicine Studies 2 (3):185-195.
    This paper aims to trace individual as well as collective aspects of ‘sight styles’ in diagnostic computed tomography. Radiologists need to efficiently translate the visualized data from the living human body into a reliable and significant diagnosis. During this process, their visual thinking and the created images are incorporated into a complex network of other visualizations, communication strategies, professional traditions, and (tacit) visual knowledge. To investigate the interplay of collective as well as individual dimensions of diagnostic seeing, the concept (...)

    Integrated Turning-Ray and Reflection Tomography for Velocity Model Building in Foothill Areas.Tian Jun, Peng Gengxin, Junru Jiao, Grace Yan & Xianhuai Zhu - 2018 - Interpretation: SEG 6 (4):SM63-SM70.
    A special challenge for land seismic exploration is estimating velocities, in part due to complex near-surface structures, and in some instances because of rugose topography over foothills. We have developed an integrated turning-ray and reflection-tomographic method to face this challenge. First, turning-ray tomography is performed to derive a near-surface velocity-depth model. Then, we combine the near-surface model with the initial-subsurface model. Taking the combined model as starting model, we go through a reflection tomographic process to build the model for (...)

    Classical-Like Description of Quantum Dynamics by Means of Symplectic Tomography.Stefano Mancini, Vladimir I. Man'ko & Paolo Tombest - 1997 - Foundations of Physics 27 (6):801-824.
    The dynamical equations of quantum mechanics are rewritten in the form of dynamical equations for the measurable, positive marginal distribution of the shifted, rotated, and squeezed quadrature introduced in the so-called “symplectic tomography”. Then the possibility of a purely classical description of a quantum system as well as a reinterpretation of the quantum measurement theory is discussed and a comparison with the well-known quasi-probabilities approach is given. Furthermore, an analysis of the properties of this marginal distribution, which contains all (...)

    Dynamical Symmetries and Tomography.V. I. Man'ko - 1998 - Foundations of Physics 28 (3):429-438.
    The notion of dynamical symmetry is discussed in the framework of the symplectic tomography scheme for the harmonic oscillator. The stationary states are shown to appear as solutions to eigenvalue equation for “classical” probabilities. All the probabilities describing the energy levels are constructed using dynamical-symmetry operators.

    Abduction, Tomography, and Other Inverse Problems.Ilkka Niiniluoto - 2011 - Studies in History and Philosophy of Science Part A 42 (1):135-139.
    Charles S. Peirce introduced in the late 19th century the notion of abduction as inference from effects to causes, or from observational data to explanatory theories. Abductive reasoning has become a major theme in contemporary logic, philosophy of science, and artificial intelligence. This paper argues that the new growing branch of applied mathematics called inverse problems deals successfully with various kinds of abductive inference within a variety of scientific disciplines. The fundamental theorem about the inverse reconstruction of plane functions from (...)

    Two Robust Imaging Methodologies for Challenging Environments: Wave-Equation Dispersion Inversion of Surface Waves and Guided Waves and Supervirtual Interferometry + Tomography for Far-Offset Refractions.Jing Li, Kai Lu, Sherif Hanafy & Gerard Schuster - 2018 - Interpretation: SEG 6 (4):SM27-SM37.
    Two robust imaging technologies are reviewed that provide subsurface geologic information in challenging environments. The first one is wave-equation dispersion inversion of surface waves and guided waves for the shear-velocity and compressional-velocity models, respectively. The other method is traveltime inversion for the velocity model, in which supervirtual refraction interferometry is used to enhance the signal-to-noise ratio of far-offset refractions. We have determined the benefits and liabilities of both methods with synthetic seismograms and field data. The benefits of WD are that (...)

  12. 11 C-Flumazenil Positron Emission Tomography Demonstrates Reduction of Both Global and Local Cerebral Benzodiazepine Receptor Binding in a Patient with Stiff Person Syndrome.N. Galldiks, A. Thiel, C. Haense, G. R. Fink & R. Hilker - 2008 - Journal of Neurology 255 (9).
    Stiff Person Syndrome is a rare autoimmune disorder associated with antibodies against glutamic acid decarboxylase, the key enzyme in γ -aminobutyric acid synthesis. In order to investigate the role of cerebral benzodiazepinereceptor binding in SPS, we performed [ 11 C]flumazenil positron emission tomography in a female patient with SPS compared to nine healthy controls. FMZ is a radioligand to the postsynaptic central benzodiazepine receptor which is co-localized with the GABA-A receptor. In the SPS patient, we found a global reduction (...)

In this work, the application value of 3D printing technology in the treatment of cardiovascular diseases has been explored via comparison study between the 3D printed vascular solid model and the computer aided design model. In this paper, a new framework is proposed to achieve a (...)
