  1. 1. Improving the experimental setup for ultrasound-optical tomography imaging

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Ibtisam Dahir Ahmed; [2023]
    Keywords : Ultrasound-optical tomography UOT ; thulium-doped lithium niobate;

    Abstract : According to Bröstcancer förbundet, mammography is not efficient at detecting tumors in dense breast tissue or diagnosing breast cancer at its early stages. Ultrasound-optical tomography (UOT) is an imaging technique in development and has the potential for deep-tissue imaging. READ MORE

  3. 2. Chromia-Alumina Thin Films from Alkoxide Precursors : From Precursor Synthesis to Deposition and Characterisation

    University essay from Uppsala universitet/Oorganisk kemi

    Author : Elina Elvelo; [2023]
    Keywords : alkoxide; synthesis; thin film; coating; alumina; chromia; spinodal decomposition;

    Abstract : A hetero-bimetallic alkoxide CrAl3(OiPr)12 was synthesised through metathesis of achromium(III)chloride THF complex (CrCl3 . 3 THF) and 3 KAl(OiPr)4.It was used as a single sourceprecursor to make oxide powders and films with 1:3 chromium/aluminium compositionthrough sol-gel synthesis.

  4. 3. Dielectric Characterization of Bone Using Ultra Wide Band Microwave Transmission Probe

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Abhinav Singh; [2022]
    Keywords : ;

    Abstract : The body has the capability of reabsorbing and generating new bone throughout life. Bone remains healthy as long it maintains the equal amount of old and new bones. Bone loss is occurred when the old bone absorbed is more and new bone created is less. Osteoporosis is a very common bone disease among men and women in their later years. READ MORE

  5. 4. 2D & 3D phase retrieval for propagation-based X-ray phase-contrast tomography

    University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Author : Philip Stjärneblad; [2021]
    Keywords : Propagation-based X-ray phase-contrast tomography; PB-PCT; Propagation-based X-ray phase-contrast Imaging; PB-PCI; 2d phase retrieval; 3d phase retrieval; TIE; sinogram consistency; reconstruction artefacts; Science General;

    Abstract : Propagation-based X-ray phase-contrast tomography is a 3d imaging technique that utilizes two-dimensional projections from different angular views $\theta =[0,\pi]$ to reconstruct the 3D object information. The phase-contrast allows for higher feature contrast than conventional transmission tomography, as the phase interference gives rise to a sharp edge contrast. READ MORE
