  1. 21. Multi-spectral X-ray imaging with a laser-plasma accelerator

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

    Author : Andrea Angella; [2022]
    Keywords : Multi-spectral imaging; single-photon counting; X-ray absorption spectroscopy; XAS; LWFA; laser-wakefield acceleration; K-edge; imaging; metal-detection algorithm; Physics and Astronomy;

    Abstract : This master thesis focuses on the creation of an algorithm to perform multispectral imaging of a metallic target using X-rays. The generation of an ultrashort high-power low-divergent X-ray beam is performed by means of a Ti:Sapphire laser driven wake-field plasma accelerator. READ MORE

  3. 22. Automated HER2 Scoring of Breast Cancer Tissue using Upconverting Nanoparticle Images

    University essay from Lunds universitet/Matematik LTH

    Author : Adam Belfrage; Alexander Wik; [2022]
    Keywords : HER2-scoring; image analysis; interpretability; digital pathology; computer aided pathology; whole slide imaging; ASCO-guidelines; singular value decomposition; shape models; Bayesian classification; Biology and Life Sciences; Medicine and Health Sciences; Technology and Engineering; Mathematics and Statistics;

    Abstract : Computer aided pathology is becoming more and more of a requirement within pathology due to increased demand of individualised treatments and personalised medicine. Because of the advance of digital pathology in recent years, where a high resolution camera acquire images of microscope slides, pathologists can now assess tissue samples in digital images.

  4. 23. Phase-Contrast Imaging, Towards G2-less Grating Interferometry With Deep Silicon

    University essay from KTH/Fysik

    Author : Rickard Brunskog; [2022]
    Keywords : Phase-contrast imaging; phase-contrast; CT-scanning; Computed-tomography; 1 micrometer resolution x-ray; grating-less phase-contrast imaging; Faskontraströntgen; faskontrast; CT-skanning; 1 mikrometer upplösning x-ray; gitterlös faskontrast; datortomografi;

    Abstract : Conventional phase-contrast imaging entails stepping an analyser grating across the detector to resolve the interference pattern caused by the x-rays after passing through a series of gratings in a so-called Talbot-Lau interferometer. However, the analyser grating in the interferometer poses a challenge, not only due to the machinery and alignment required but also due to each exposure delivering a dose to the subject. READ MORE

  5. 24. Investigation of Registration Methods for High Resolution SAR-EO Imagery

    University essay from Linköpings universitet/Datorseende

    Author : Niclas Hansson; [2022]
    Keywords : SAR; FFT; MI; Image Registration;

    Abstract : With advancements in space technology, remote sensing applications, and computer vision, significant improvements in the data describing our planet are seen today. Researchers want to gather different kinds of data and perform data fusion techniques between them to increase our understanding of the world. READ MORE

  6. 25. Image analysis on the structure of the Achilles tendon

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Linnea Andersson; [2022]
    Keywords : biomechanics; Achilles tendon; image analysis; image processing; tendons; synchrotron; computed tomography; phase contrast; Technology and Engineering;

    Abstract : The Achilles tendon is the largest tendon of the human body which makes injuries of it very painful and incapacitating. A common factor of the pain are heterotopic ossifications, which are mineral deposits occurring inside the normal tendon tissue. Why and how heterotopic ossifications occur are somewhat unknown.
