  1. 1. Silicon Strip Detectors for Scanned Multi-Slit X-Ray Imaging

    Författare :Mats Lundqvist; KTH; []
    Nyckelord :x-ray; silicon strip detectors; mammography; multi-slit; scanned slit; edge-on;

    Sammanfattning : Digital imaging systems for medical applications must bebased upon highly efficient detectors to ensure low patientdose. This is particularly important in screening mammographybecause of the large number healthy women that is examined. Amammography system must also provide high spatial and contrastresolution. LÄS MER

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

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

    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. 3. Vertical charge transport in conjugated polymers

    Författare :Vasyl Skrypnychuk; Alexandr Talyzin; Ellen Moons; Umeå universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; organic electronics; conjugated polymers; nanotechnology; nanoimprint lithography; graphene; P3HT; charge transport; X-ray diffraction; structure; crystallite orientation; Materials Science; materialvetenskap;

    Sammanfattning : Conjugated polymers are novel organic electronic materials highly important for organic photovoltaic applications. Charge transport is one of the key properties which defines the performance of conjugated polymers in electronic devices. LÄS MER

  5. 4. Methanol Masers: Tracer of Star Formation

    Författare :Vincent Minier; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The Onsala VLBI group has been conducting an extensive study of the Northern hemisphere methanol masers using the European VLBI Network (EVN) and the VLBA since early 1997. In parallel, a blind survey of the Galactic plane has been undertaken in order to discover new 6. LÄS MER

  7. 5. Extrasolar Kuiper and asteroid belts Modelling far-infrared dust emission

    Författare :Joachim Wiegert; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Stars: binaries - Stars: circumstellar matter - Infrared: stars - Infrared: planetary systems - Submillimeter: stars;

    Sammanfattning : The first detections of circumstellar dust emission were announced in the mid 1980s. Direct observations of the edge-on disc of beta Pictoris provided evidence that the dust was part of possible planetary systems. About a decade later, in 1995, the first confirmed extrasolar planet around a main sequence star (51 Pegasi b) was announced. LÄS MER
