1. 1. Programmert interpretasjon. Serinetten som kilde till 1700-tallets musikalske fremførelsespraksis

   Författare :Bjørn A Bratsberg; Göteborgs universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; serinette; automatic organs; performance practice; Engramelle; Dom Bedos; tonotechnie; unequal notes;

   Sammanfattning : In his famous treatise on organ-building, L'art du facteur d'orgues (1766-78), the French Bénédictine monk, organist and organ-builder Dom François Bédos de Celles devotes a chapter to the procedure of pinning cylinders for automatic organs. The chapter, based on the treatise La Tonotechnie by Dom Bédos' contemporary Joseph Engramelle, Dom Bédos contains detailed descriptions of basic practices of performance, including the precise nature of ornaments, articulation and notes inégales, with the aim of making possible the mechanical reproduction of a good human performance.

   Sammanfattning : Cancer is one of the leading causes of death worldwide. In 2020, there were around 10 million cancer deaths and nearly 20 million new cancer cases in the world. Radiation therapy is essential in cancer treatments because half of the cancer patients receive radiation therapy at some point. LÄS MER

4. 3. Surface guided radiotherapy

   Sammanfattning : Modern radiotherapy aims to treat the decease while minimizing the radiation dose to the adjacent normal tissue, to minimize acute and late effects of the treatment. The foremost technological approaches have been intensity modulated radiotherapy (IMRT) and intensity modulated proton therapy (IMPT) in combination with image guided radiotherapy (IGRT). LÄS MER

5. 4. Visualization and Haptics for Interactive Medical Image Analysis

   Författare :Erik Vidholm; Ingela Nyström; Ewert Bengtsson; Gábor Székely; Uppsala universitet; []
   Nyckelord :Bildanalys; medical image analysis; haptic rendering; volume visualization; interactive segmentation; Bildanalys;

   Sammanfattning : Modern medical imaging techniques provide an increasing amount of high-dimensional and high-resolution image data that need to be visualized, analyzed, and interpreted for diagnostic and treatment planning purposes. As a consequence, efficient ways of exploring these images are needed. LÄS MER

7. 5. Improving Multi-Atlas Segmentation Methods for Medical Images

   Författare :Jennifer Alvén; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Supervised learning; semantic segmentation; multi-atlas segmentation; conditional random fields; label fusion; feature-based registration; image registration; random decision forests; convolutional neural networks; medical image segmentation;

   Sammanfattning : Semantic segmentation of organs or tissues, i.e. delineating anatomically or physiologically meaningful boundaries, is an essential task in medical image analysis. One particular class of automatic segmentation algorithms has proved to excel at a diverse set of medical applications, namely multi-atlas segmentation. LÄS MER
