  1. 1. Radiography and bone scintigraphy in osteoarthritis of the knee: comparison with MR imaging

    Författare :Torsten Boegård; Lund Diagnostisk radiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; radiologi; Klinisk fysiologi; medical instrumentation; tomography; radiology; Clinical physics; MR imaging; bone scintigraphy; osteophyte; joint space width; weight-bearing; radiograms; Knee joint; osteoarthritis; tomografi; medicinsk instrumentering;

    Sammanfattning : The aim was to compare radiography of the tibiofemoral joint (TFJ) and the patellofemoral joint (PFJ), as well as bone scinigraphy with MR imaging in middle-aged individuals with chronic knee pain in the format of a prospective study of knee osteoarthritis. Individuals aged 35-54 years with chronic knee pain were identified. LÄS MER

  3. 2. Symmetry Filters Applied to Fingerprints : Representation, Feature extraction and Registration

    Författare :Kenneth Nilsson; Högskolan i Halmstad; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fingerprint recognition; symmetry filters; orientation field; multiscale filtering; singular points; orientation radiograms; registration; multiexpert; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : A common framework for feature extraction in fingerprints is proposed by use of certain symmetries. The proposal includes representation, filters, and filtering techniques for common features including minutiae points, singular points and the ridge and valley patterns. LÄS MER

  4. 3. The temporomandibular joint : Tomopraphic and CT assesment of its bone demarcations with reference to adjacent organs

    Författare :Jan Ahlqvist; Annika Isberg; Sven-Ola Hietala; Umeå universitet; []
    Nyckelord :Temporomandibular joint; anatomy; tomography; CT; artefacts; odontologi; Odontology;

    Sammanfattning : The wall of the temporal bone separating the temporomandibular joint (TMJ) from surroundings organs, can be very thin and also have development defects. Distortion effects in the radiographic reproduction of these bone walls can result in misinterpretations when exanimating suspected pathologic changes in the region. LÄS MER
