  1. 1. Virtual H&E Staining Using PLS Microscopy and Neural Networks

    Master-uppsats, Lunds universitet/Matematik LTH

    Författare :Sally Vizins; Hanna Råhnängen; [2024]
    Nyckelord :Deep learning; Virtual staining; Skin tissue; Hematoxylin Eosin; H E; Pathology; Carcinoma; Point light source illumination; Neural Networks; GANs; Generative adversarial networks; CNNs; Convolutional neural networks; Relativistic generative adversarial network; Unet; Digital microscopy; Attention-Unet; Dense-Unet; Mathematics and Statistics;

    Sammanfattning : Histopathological examination, crucial in diagnosing diseases such as cancer, traditionally relies on time- and resource-consuming, poorly standardized chemical staining for tissue visualization. This thesis presents a novel digital alternative using generative neural networks and a point light source (PLS) microscope to transform unstained skin tissue images into their stained counterparts.

  3. 2. Virtual Staining of Blood Cells using Point Light Source Illumination and Deep Learning

    Master-uppsats, Lunds universitet/Matematik LTH

    Författare :Joel Wulff; [2022]
    Nyckelord :Deep learning; virtual staining; blood; cells; GANs; Generative adversarial networks; CNNs; convolutional neural networks; ESRGAN; Unet; digital microscopy; Mathematics and Statistics;

    Sammanfattning : Blood tests are an important part of modern medicine, and are essentially always stained using chemical colorization methods before analysis by computational or manual methods. The staining process allows different parts of blood cells to be discerned that would be unnoticeable in unstained blood. LÄS MER

  4. 3. Deep Learning Based Focus lnterpolation for Whole Slide Images

    Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Davis Nicmanis; [2022]
    Nyckelord :;

    Sammanfattning : Whole slide imaging is a crucial component of digital pathology, which emulates conventional microscopy by scanning the entire microscope slide. It results in a large digital image that can be examined by a cytopathologist or used in further computer-assisted image analysis. LÄS MER

  5. 4. Correlation between microstructure and fatigue cracks in cast aluminium alloy A205

    Kandidat-uppsats, Jönköping University/Tekniska Högskolan

    Författare :Max Holmberg; Pontus Sundberg; [2022]
    Nyckelord :Aluminium Alloy A205;

    Sammanfattning : Materials research in the aerospace industry is, among other things, focused on reducing the weight and increasing the life of components. Materials with high strength and long lifespan are therefore examined. LÄS MER

  7. 5. Bildanalysbaserad retikulocytnumrering : Utvärdering av en prototyp av ett program för retikulocytnumrering i perifiera blodprov

    Kandidat-uppsats, Malmö universitet/Fakulteten för hälsa och samhälle (HS)

    Författare :Patryk Stendel; [2022]
    Nyckelord :automated cell counter; CellaVision; digital hematology; evaluation; manual microscopy; reticulocyte; automatiserad cellräknare; CellaVision; digital hematologi; manuell mikroskopering; retikulocyt; utvärdering;

    Sammanfattning : Allt mer forskning kring digitala bildanalysplattformar sker då de har visat lika bra eller bättre prestation än existerande manuella och automatiserade metoder samt effektiviserat handläggningstiden för patientprov. Nyligen har företaget CellaVision utvecklat ett prototypprogram som via bildanalys kan räkna och klassificera retikulocyter. LÄS MER
