1. 26. Image Processing for Quantitative Scintillation-Camera Imaging. Application to Radionuclide Therapy

   Författare :Katarina Sjögreen Gleisner; Lund Medicinsk strålningsfysik; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; tomografi; radiologi; Klinisk fysiologi; medical instrumentation; tomography; radiology; 131-I; Clinical physics; SPECT; conjugate-view; volume quantification; activity quantification; image registration; image segmentation; medicinsk instrumentering; Nuclear medicine; radiobiology; Nukleärmedicin; radiobiologi; Radiopharmaceutical technology; Radiofarmaceutisk teknik;

   Sammanfattning : Individual-based determinations of the absorbed dose in radionuclide therapy largely rely on absolute measurement of the activity distribution and its redistribution over time. Scintillation-camera imaging is the most commonly employed measuring technique, applied in planar or SPECT mode, sometimes in combination with structural images from CT. LÄS MER

3. 27. Image Filtering Methods for Biomedical Applications

   Författare :M. Khalid Khan Niazi; Ewert Bengtsson; Ingela Nyström; Lucas J. van Vliet; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Digital image analysis; Image filtering; Intensity inhomogeneity correction; Empirical mode decomposition; Particle Swarm optimization; Image registration; Computerized Image Processing; Datoriserad bildbehandling;

   Sammanfattning : Filtering is a key step in digital image processing and analysis. It is mainly used for amplification or attenuation of some frequencies depending on the nature of the application. Filtering can either be performed in the spatial domain or in a transformed domain. LÄS MER

4. 28. Tailoring the Unique Figure

   Författare :Niina Hernández; Gothenburg University; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; dressmaking; pattern construction; pattern adaptation; figure registration; body measurement; disfigurement; clothes; garment; made-to-measure; mass customisation; klädsömnad; mönsterkonstruktion; tillskärning;

   Sammanfattning : Today, it is possible to offer customers a garment to order according to their desires and body figure. The new, more automatic, equipment and software make the process faster and possible to realise. However it is important to have the basic knowledge about how to adapt the patterns according to the many variations of figures that exists. LÄS MER

5. 29. Representation Learning and Information Fusion : Applications in Biomedical Image Processing

   Författare :Elisabeth Wetzer; Nataša Sladoje; Fred Hamprecht; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Representation Learning; Texture Descriptors; Equivariant Neural Networks; Contrastive Learning; Image Classification; Image Registration; Image Retrieval; Digital Pathology; Computerized Image Processing; Datoriserad bildbehandling;

   Sammanfattning : In recent years Machine Learning and in particular Deep Learning have excelled in object recognition and classification tasks in computer vision. As these methods extract features from the data itself by learning features that are relevant for a particular task, a key aspect of this remarkable success is the amount of data on which these methods train.

7. 30. Counting deaths, accounting for lives : Novel applications of standardised verbal autopsy methods for augmented health systems

   Författare :Laith Hussain-Alkhateeb; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Verbal autopsy; cause of death; vital registration; health system; surveillance; World Health Organization;

   Sammanfattning : Half of the world’s deaths and their causes are never recorded by virtue of the under-resourced civil registration and vital statistics (CRVS) systems which limits capacity of health systems to respond to population needs. Verbal autopsy (VA) has emerged as a pragmatic approach for determining causes of death using standard interviews including signs, symptoms and circumstances of death, conducted with the bereaved family.
