1. 11. Clinical Assessment for Deep Vein Thrombosis using Support Vector Machines : A description of a clinical assessment and compression ultrasonography journaling system for deep vein thrombosis using support vector machines

   University essay from KTH/Skolan för datavetenskap och kommunikation (CSC)

   Author : Öberg Daniel; [2015]
   Keywords : clinical assessment; compression ultrasonography; deep vein thrombosis; support vector machines;

   Abstract : This master thesis describes a journaling system for compression ultrasonography and a clinical assessment system for deep vein thrombosis (DVT). We evaluate Support Vector Machines (SVM) models with linear- and radial basis function-kernels for predicting deep vein thrombosis, and for facilitating creation of new clinical DVT assessment.

3. 12. Semi-Analytical Finite Element method for guided waves in civil engineering plate-like structures

   University essay from Lunds universitet/Teknisk geologi; Lunds universitet/Väg- och vattenbyggnad (CI)

   Author : Christian Nielsen; [2015]
   Keywords : seismics; structural health monitoring; lamb waves; SAFE; semi analytical finite element; wave guide finite element; non destructive testing; civil engineering; ultrasound; ultrasonography; comsol; wave guide; plate; Technology and Engineering;

   Abstract : Guided waves have a signicant potential for Structural Health Monitoring (SHM) and Non-Destructive Testing (NDT) due to their relatively long distance of propagation and sensitivity to discontinuities along the propagation path, anywhere through the material thickness. The inability to model wave guides of arbitrary cross-section using current matrix methods, has led to the development of a technique called Semi-Analytical Finite Element (SAFE). READ MORE

4. 13. Pregnancy detection in reindeer (Rangifer tarandus tarandus) : comparison of transrectal ultrasound, abdominal palpation and herders' visual cues in late gestation

   University essay from SLU/Dept. of Animal Nutrition and Management

   Author : Elisabeth Paul; [2014]
   Keywords : reindeer; pregnancy; ultrasonography; palpation; visual examination; herders predation;

   Abstract : Pregnancy detection during late gestation (last trimester) in domesticated reindeer (Rangifer tarandus tarandus) gives the possibility to select and enclose the pregnant reindeer during calving as protection against predation. The aim of the present study was to compare transrectal ultrasonography and palpation, and also to describe visual examination as traditionally used by herders as pregnancy detection methods in reindeer.

5. 14. Realtime Virtual 3D Image of Kidney Using Pre-Operative CT Image for Geometry and Realtime US-Image for Tracking

   University essay from Uppsala universitet/Avdelningen för visuell information och interaktion

   Author : Sebastian Ärleryd; [2014]
   Keywords : computer vision; computed tomography; ultrasonography; visualisation; real time; interactive; segmentation; SURF; RANSAC;

   Abstract : In this thesis a method is presented to provide a 3D visualization of the human kidney and surrounding tissue during kidney surgery. The method takes advantage of the high detail of 3D X-Ray Computed Tomography (CT) and the high time resolution of Ultrasonography (US). READ MORE

6. 15. Compressive Sensing in Medical Ultrasonography

   University essay from KTH/Ljud- och bildbehandling

   Author : Julien Richy; [2012]
   Keywords : ;

   Abstract : The recently introduced compressive sensing (CS) theory allows – under certain assumptions – to recover a signal sampled below the Nyquist sampling limit. Compressive sensing can be applied for two purposes. First, to decrease the number of samples needed to capture the information, thus allowing faster acquisitions. READ MORE
