  1. 1. Towards Clinical Implementation of Dynamic Positron Emission Tomography in Neurodegenerative Diseases

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : My Jonasson; Uppsala universitet.; [2018]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Positron emission tomography; PET; Molecular imaging; Quantification; Kinetic modelling; Parametric images; Alzheimer’s disease; Parkinson’s disease; Radiology; Radiologi;

    Abstract : Alzheimer’s disease (AD) and Parkinson’s disease (PD) are the two most common neurodegenerative disorders worldwide. Positron emission tomography (PET), together with suitable biomarkers, can aid in the clin-ical evaluation as well as in research investigations of these diseases. READ MORE

  2. 2. Filter Bank Techniques for Signal and Image Processing

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Farook Sattar; [1996]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Imaging; Higher-order statistics; Detection; Echo cancelling; Multirate system; Multiscale; Image enhancement; Time-frequency analysis and synthesis; Non-stationary signals; Filter bank; Non-parametric estimation; image processing; Bildbehandling; Signal processing; Signalbehandling;

    Abstract : This thesis consists of five parts, each of which considers methods based on filter banks for different applications in signal and image processing. In Part I, a non-parametric estimation method is proposed using filter banks to estimate signals with varying waveforms and arrival times. READ MORE

  3. 3. Quantitative methods for tumor imaging with dynamic PET

    University dissertation from Umeå : Umeå Universitet

    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Dynamic positron emission tomography; PET; tumor imaging; compartment modeling; Monte Carlo; radiofysik; radiofysik;

    Abstract : There is always a need and drive to improve modern cancer care. Dynamic positron emission tomography (PET) offers the advantage of in vivo functional imaging, combined with the ability to follow the physiological processes over time. READ MORE

  4. 4. Decoding the complex brain multivariate and multimodal analyses of neuroimaging data

    University dissertation from Umeå : Umeå University

    Author : Alireza Salami; Umeå universitet.; [2012]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; multivariate analysis; univariate analysis; multimodal imaging; episodic memory; aging; functional magnetic resonance imaging; diffusion tensor imaging; biology; biologi; Psychology; psykologi; datoriserad bildanalys; Computerized Image Analysis;

    Abstract : Functional brain images are extraordinarily rich data sets that reveal distributed brain networks engaged in a wide variety of cognitive operations. It is a substantial challenge both to create models of cognition that mimic behavior and underlying cognitive processes and to choose a suitable analytic method to identify underlying brain networks.

  5. 5. Ultrafast Photoionization Dynamics Studied with Coincidence Momentum Imaging Spectrometers

    University dissertation from Department of Physics, Lund University

    Author : Yu-Chen Cheng; Lund University.; Lunds universitet.; [2019-03-01]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Photoionization; High-order Harmonic Generation; Extreme Ultraviolet; Free-Electron Laser; Molecular Dissociation; Charge Transfer; Coincidence Measurement; Momentum Imaging; Electron Wave Packet;

    Abstract : The time scale of the dynamics in atoms and molecules varies from attoseconds (10-18) to picoseconds (10-12) depending on the size of the particles. To study such dynamics, ultrafast light pulses are needed to trigger and capture the reaction. One of the most direct methods consists in ionizing the system and observing the following response.
