  1. 1. Positron Emission Tomography with Three-Dimensional Reconstruction

    University dissertation from Radiation Physics, Lund

    Author : Kjell Erlandsson; [1996]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; radiology; Clinical physics; quantitation; reconstruction; three-dimensional; tomography; positron; emission; 3D; PET; medical instrumentation; Klinisk fysiologi; radiologi; tomografi; medicinsk instrumentering;

    Abstract : In this thesis, the developments of two different low-cost scanners for positron emission tomography (PET) based on 3D acquisition, are presented. 3D reconstruction methods for these systems are also presented. READ MORE

  2. 2. Three-dimensional ultrasound studies of normal and abnormal ovaries

    University dissertation from Department of Clinical Sciences, Lund University

    Author : Ligita Jokubkiene; Lunds universitet.; Lund University.; [2012]

    Abstract : Popular Abstract in Swedish Äggstockarna genomgår förändringar under en normal menstruationscykel. I samband med tumörväxt i äggstockarna utvecklas nya blodkärl. Dessa förändringar kan upptäckas med både tvådimensionellt (2D) och tredimensionellt (3D) gråskale- och Doppler-ultraljud. READ MORE

  3. 3. Three - dimensional ultrasound studies of the cervix in pregnancy

    University dissertation from Medicinsk Informationsteknik, Malmö

    Author : Linas Rovas; Lunds universitet.; Lund University.; [2005]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; andrology; gynaecology; Obstetrics; Prostaglandin .; Labor induction .; Spontaneous delivery .; Pregnancy .; Cervix uteri .; Blood flow indices .; Doppler ultrasound .; Three-dimensional imaging .; sexuality; reproduction; Obstetrik; sexualitet; reproduktion; gynekologi; andrologi;

    Abstract : Popular Abstract in Swedish Tre-dimensionell ultraljudsundersökning av livmodertappen (cervix) Syftet med avhandlingen var att utvärdera förändringar i livmodertappen (cervix) med tre-dimensionellt ultraljud och utreda om tre-dimensionellt power Doppler ultraljud kan förutsäga tiden till spontan eller inducerad förlossning hos överburna, gravida kvinnor. Avhandlingen baseras på fem studier: reproducibilitet av cervixmätningar (studie I), referensvärde för normala mätningar på cervix med tre-dimensionellt ultraljud under graviditet (studierna II och III) samt förmåga att förutsäga tiden till spontan eller inducerad förlossning hos överburna, gravida kvinnor med tre-dimensionellt power Doppler ultraljud (studierna IV och V).
