2. 1. Core Acquisition Management in Remanufacturing : Current Status and Modeling Techniques

   Author : Shuoguo Wei; Ou Tang; Erik Sundin; Jan Olhager; Moritz Fleischmann; Linköpings universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Core acquisition; remanufacturing; closed-loop supply chain; quantitative modeling; return uncertainties;

   Abstract : Remanufacturing is an important product recovery option that benefits our sustainable development. Cores, i.e. the used products/parts, are essential resources for remanufacturing. READ MORE

4. 2. Computational Diffusion MRI: Optimal Gradient Encoding Schemes

   Author : Mohammad Alipoor; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gradient Encoding Scheme; ADC imaging; Diffusion MRI; D-optimal experiment design; Diffusion Tensor Imaging; Optimal Image acquisition; Second and Fourth Order Tensors.; Diffusion Kurtosis Imaging;

   Abstract : Diffusion-weighted magnetic resonance imaging (dMRI) is a non-invasivestructural imaging technique that provides information about tissue microstructures.Quantitative measures derived from dMRI reflect pathologicaland developmental changes in living tissues such as human brain.

5. 3. Evaluation of Regularized Image Reconstruction for Clinical Positron Emission Tomography

   Author : Elin Lindström; Mark Lubberink; Jens Sörensen; Anders Sundin; Anne Larsson Strömvall; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Positron emission tomography; PET CT; molecular imaging; image reconstruction; regularized reconstruction; quantification; oncology; neurology; cardiology; Medicinsk radiofysik; Medical Radiophysics;

   Abstract : Positron emission tomography (PET) combined with computed tomography (CT) is a widely used noninvasive molecular imaging modality with a broad range of clinical applications in oncology, neurology, and cardiology. Producing imperative image quality and accurate quantification are important driving forces behind the technological advances within PET image reconstruction and system development. READ MORE

6. 4. Methods of image acquisition and calibration for x-ray computed tomography

   Author : Martin Sjölin; Mats Danielsson; J. Webster Stayman; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Medical Technology; Medicinsk teknologi;

   Abstract : X-ray computed tomography (CT) is a common medical imaging device for acquiring high-resolution 3D images of the interior of the human body. The images are formed by mathematical reconstruction from hundreds of planar x-ray images that have been acquired during less then a second. READ MORE

7. 5. Quantifying image quality in diagnostic radiology using simulation of the imaging system and model observers

   Author : Gustaf Ullman; Michael Sandborg; Gudrun Alm Carlsson; Nicolas Pallikarakis; Linköpings universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; radiology; radiation physics; image quality; optimisation; effective dose; chest radiography; Radiological physics; Radiofysik;

   Abstract : Accurate measures of both clinical image quality and patient radiation risk are needed for successful optimisation of medical imaging with ionising radiation. Optimisation in diagnostic radiology means finding the image acquisition technique that maximises the perceived information content and minimises the radiation risk or keeps it at a reasonably low level.
