  2. 1. Signal Processing for Spectroscopic Applications

    Author : Erik Gudmundson; Peter Stoica; Peter Händel; Stoica Stoica; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; spectral estimation; spectroscopic techniques; MRI; NMR; NQR; signal detection; parameter estimation; missing data; non-uniform sampling; damped sinusoids; detection of explosives; T1-mapping; relaxometry; brain imaging; skin imaging; blood velocity estimation; medical ultrasound; Signal processing; Signalbehandling; Elektroteknik med inriktning mot reglerteknik; Electrical Engineering with specialization in Automatic Control;

    Abstract : Spectroscopic techniques allow for studies of materials and organisms on the atomic and molecular level. Examples of such techniques are nuclear magnetic resonance (NMR) spectroscopy—one of the principal techniques to obtain physical, chemical, electronic and structural information about molecules—and magnetic resonance imaging (MRI)—an important medical imaging technique for, e.

    Abstract : Diagnostic ultrasound (US) is safer, quicker and cheaper than other diagnostic imaging modalities. Over the past two decades, the applications of US imaging has been widened due to the development of injectable, compressible and encapsulated microbubbles (MBs) that provide an opportunity to improve conventional echocardiographic imaging, blood flow assessment and molecular imaging.

  5. 3. Preoperative deposit of autologous blood. Effects on inflammatory mediators

    Author : Monica Hyllner; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; allogeneic; autologous; complement; cytokines; blood storage; erythropoiesis; hysterectomy; plasma; prestorage leucocyte filtration; rHuEPO; whole blood.;

    Abstract : Blood contains complex cascade systems and substances that can be activated during the processing of blood components and storage. Allogeneic blood, i.e. blood from someone else, is normally separated into components before storage and transfusion, while autologous blood (the patient s own blood) often is used as whole blood.

  6. 4. Level Set Segmentation and Volume Visualization of Vascular Trees

    Author : Gunnar Läthén; Reiner Lenz; Magnus Borga; Lasse Riis Østergaard; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; level set methods; image segmentation; edge detection; visualization; volume rendering; blood vessels; angiography; vascular trees;

    Abstract : Medical imaging is an important part of the clinical workflow. With the increasing amount and complexity of image data comes the need for automatic (or semi-automatic) analysis methods which aid the physician in the exploration of the data. READ MORE

  7. 5. Automated Assessment of Blood Flow in the Cardiovascular System Using 4D Flow MRI

    Author : Mariana Bustamante; Tino Ebbers; Carljohan Carlhäll; Petter Dyverfeldt; Michael Markl; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MRI; 4D Flow MRI; Image Analysis; Segmentation;

    Abstract : Medical image analysis focuses on the extraction of meaningful information from medical images in order to facilitate clinical assessment, diagnostics and treatment. Image processing techniques have gradually become an essential part of the modern health care system, a consequence of the continuous technological improvements and the availability of a variety of medical imaging techniques.
