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

   University essay from Lunds universitet/Matematik LTH

   Author : Sally Vizins; Hanna Råhnängen; [2024]
   Keywords : 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;

   Abstract : 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. Assessment and evaluation of heterogeneity in data from immune infiltration spatial niches in lung cancer

   University essay from Lunds universitet/Matematisk statistik

   Author : Mahta Keivani Najafabadi; [2023]
   Keywords : Mathematics and Statistics;

   Abstract : The protein biomarker expressions in three types of sampled immune INFILTration spatial niches in lung cancer tissue were measured using the new technology Digital Spatial Profiler (DSP). The three types of immune INFILTration that were observed in lung tumors were STROMA identified as immune cells separate from tumor cells, Tertiary lymphoid structures (TLS) identified as dense structures of organized immune cells and finally Infiltraterate where immune cells dispersed among and in direct contact with tumor cells (INFILT).

4. 3. Validation of Simultaneous T1 and T2 Mapping Using Cardiac Magnetic Resonance Fingerprinting in Self-Constructed Phantoms : An Analysis of the Reproducibility and Accuracy

   University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

   Author : Sasithon Meesan; [2023]
   Keywords : Cardiac Magnetic Resonance Fingerprinting cMRF ; Cardiac Magnetic Resonance Imaging CMR ; Simultaneous T1 and T2 Mapping; Validation; Accuracy; Reproducibility; Cardiac Magnetic Resonance Fingerprinting cMRF ; Kardiovaskulär Magnetresonans CMR ; Simultant T1 och T2 Parametrisk-Karaktärisering; Validering; Noggrannhet; Reproducerbarhet;

   Abstract : Quantitative cardiac magnetic resonance imaging (CMR) has gained traction within both the clinical and research field due to high prevalence of cardiovascular diseases. Cardiac magnetic resonance fingerprinting (cMRF) is a novel approach introduced to address the limitation associated with evaluation of multiparametric quantitative CMR. READ MORE

5. 4. Comparative Analysis of Transformer and CNN Based Models for 2D Brain Tumor Segmentation

   University essay from Linköpings universitet/Institutionen för medicinsk teknik

   Author : Henrik Träff; [2023]
   Keywords : Machine Learning; ML; AI; Computer vision; Vision Transformer; Swin Transformer; U-Net; nnU-Net; Brain Tumor Segmentation; Deep Learning;

   Abstract : A brain tumor is an abnormal growth of cells within the brain, which can be categorized into primary and secondary tumor types. The most common type of primary tumors in adults are gliomas, which can be further classified into high-grade gliomas (HGGs) and low-grade gliomas (LGGs). READ MORE

6. 5. Objective assessment of drawer test in cruciate ligament rupture in dogs

   University essay from SLU/Dept. of Clinical Sciences

   Author : Ellinor Harlén; [2023]
   Keywords : cranial cruciate ligament rupture; CCLR; canine; dog; drawer test; diagnostics; motion analysis;

   Abstract : Cranial cruciate ligament rupture (CCLR) is one of the most common orthopaedic diagnosesin dogs. There are different methods to diagnose CCLR, but only a few can be considered as both noninvasive and objective. READ MORE
