    Sammanfattning : Throughout the last century, medical imaging has come to revolutionise the way we diagnose disease, and is today an indispensable part of virtually any clinical practice. In cardiovascular care imaging is extensively utilised, and the development of novel techniques promises refined diagnostic abilities: ultrasound elastography allows for constitutive tissue assessment, 4D flow magnetic resonance imaging (MRI) enables full-field flow mapping, and micro-Computed Tomography (CT) permits high-resolution imaging at pre-clinical level.

    Sammanfattning : The opportunity to non-invasively probe the structure and function of different parts of the human body makes medical imaging an indispensable tool in clinical diagnostics and related fields of research. Especially neuroscientists rely on modalities like structural or functional Magnetic Resonance Imaging, Computed Tomography or Positron Emission Tomography to study the human brain in vivo. LÄS MER

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

    Författare :Martin Sjölin; Mats Danielsson; J. Webster Stayman; KTH; []

    Sammanfattning : 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. LÄS MER

  4. 4. Synthesis and Characterization of Nanoprobes for X-Ray Fluorescence Computed Tomography (XFCT) Bio-imaging

    Författare :Yuyang Li; Muhammet Toprak; Hans Hertz; Ender Suvaci; KTH; []

    Sammanfattning : X-ray fluorescence computed tomography (XFCT) is an emerging biomedical imaging technique. The KTH-XFCT laboratory system offers a characteristic 24 keV emission line, and high spatial resolution (200 ?m) images. XFCT as a newly emerging modality also requires the exploration and development of suitable contrast agents. LÄS MER

  5. 5. The ADAPT scaffold as a tool for diagnostic imaging and targeted therapy

    Sammanfattning : Molecular recognition, or the specific interactions between a protein and its ligand, is central to biology and a key factor for many different clinical and technical applications. Despite antibodies being only one of many different affinity proteins, it has by far been the most successful. LÄS MER
