1. 1. Network Orientation and Segmentation Refinement Using Machine Learning

   Master-uppsats, Linköpings universitet/Institutionen för medicinsk teknik

   Författare :Michael Nilsson; Jonatan Kentson; [2023]
   Nyckelord :deep learning; semantic segmentation; orientation learning; road networks; retina networks;

   Sammanfattning : Network mapping is used to extract the coordinates of a network's components in an image. Furthermore, machine learning algorithms have demonstrated their efficacy in advancing the field of network mapping across various domains, including mapping of road networks and blood vessel networks.

3. 2. Image Segmentation and Object Identification in Cancer Tissue Slides from Fluorescence Microscopy

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen Vi3

   Författare :Sebastian Eriksson; Fredrik Forsberg; [2023]
   Nyckelord :image analysis; cancer research; fluorescent microscopy; image segmentation; bildanalys; cancerforskning; fluorescensmikroskopi; bildsegmentering;

   Sammanfattning : In cancer research, there is a need to make accurate spatial measurements in multi-layered fluorescence microscopy images. Researchers would like to measure distances in and between biological objects such as nerves and tumours, to investigate questions which includes if nerve distribution in and around tumours can have a prognostic value in cancer diagnostics.

4. 3. On the Greek Physician Praxagoras from Kos and the Development of Medicαl Thinking in Antiquity

   Master-uppsats, Lunds universitet/Grekiska (antik och bysantinsk); Lunds universitet/Masterprogram: Språk och språkvetenskap

   Författare :Lars-Ove Farnebo; [2023]
   Nyckelord :artery ies - ἀρτηρία ι; humor s – χυμός χυμοί; innate - ἔμφυτος; nerve – νεῦρον; pneuma – πνεῦμα; pulse – σφυγμός; vessel s – φλέψ φλέβες.; Languages and Literatures;

   Sammanfattning : The Greek physician Praxagoras from Kos was active around year 300 BC. He represents the transition between the Hippocratic and the Hellenistic periods in medicine. Praxagoras was the teacher of several renowned physicians active during the 3rd century BC. Although he wrote many books nothing of his writing has survived to our time. LÄS MER

5. 4. Real-time Autofocus Algorithm in Laser Speckle Contrast Imaging

   Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

   Författare :Giovanni Russo; [2023]
   Nyckelord :Laser speckle contrast imaging; Autofocus; Blind image sharpness assessment; Speckle noise; Perimed’s Perfusion Speckle Imager;

   Sammanfattning : Microcirculation is defined as the blood flow in the smallest blood vessels. Laser speckle contrast imaging (LSCI) is a full field imaging technique that provides instantaneous 2-D perfusion maps of illuminated tissues based on speckle contrast. LÄS MER

7. 5. Riskfaktorer för Strongylus vulgaris – en enkätstudie

   Master-uppsats, SLU/Dept. of Clinical Sciences

   Författare :Jessica Lernå; [2023]
   Nyckelord :Strongylus vulgaris; blodmask; stor blodmask; häst; avmaskning; riskfaktorer;

   Sammanfattning : I stort sett exponeras alla betande hästar för endoparasiter någon gång under sin levnad. Strongylus vulgaris, en av hästens stora blodmaskar, anses vara den hästparasit som är mest patogen och kan orsaka skador som är direkt fatala. Strongylus vulgaris har en fekal-oral livscykel som tar cirka sex till sju månader att fullborda. LÄS MER
