1. 1. Phase Unwrapping MRI Flow Measurements

   University essay from Uppsala universitet/Avdelningen Vi3

   Author : Mio Liljeblad; [2023]
   Keywords : phase unwrapping; computer vision; cine MRI; NMR; flow measurements; velocity encoding; venc; energy minimization; magnetic resonance; cardiac MRI; sinotubuar junction; pulmonary artery; ascending descending aorta; laplacian algorithm; iterative graph cuts; IGC; sequential tree-reweighted message passing; TRW-S; velocity to noise ratio; VNR; retrospective wrapping; energy formulation;

   Abstract : Magnetic resonance images (MRI) are acquired by sampling the current of induced electromotiveforce (EMF). EMF is induced due to flux of the net magnetic field from coherent nuclear spins with intrinsic magnetic dipole moments. READ MORE

3. 2. Comparison of In Vivo Intramuscular Fat Quantification Techniques in MRI

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

   Author : Pien Derikx; [2023]
   Keywords : Fat-water separation; Dixon technique; Intramuscular fat quantification;

   Abstract : People with cerebral palsy (CP) may develop muscle contractures, which are defined as a loss of joint range due to an increase in passive muscle stiffness [1]. Computer models suggest that intramuscular fat can increase muscle stiffness [2]. READ MORE

4. 3. FMCW mmWave Radar for Detection of Pulse, Breathing and Fall within Home Care

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Axel Trange; [2021]
   Keywords : ;

   Abstract : Countless of elderly people fall and get hurt within their homes, worldwide, every year, and as they can not always reach out for help themselves, they end up helplessly waiting for someone to notice what has occurred. Throughout this work, it is investigated if remote sensing of the mmWave FMCW radar IWR6843AOPEVM can be adopted to detect the incident of falls, and also detect the vital signs of the human subject.

5. 4. Depth Data Processing and 3D Reconstruction Using the Kinect v2

   University essay from Linköpings universitet/Datorseende; Linköpings universitet/Tekniska fakulteten

   Author : Felix Järemo Lawin; [2015]
   Keywords : RGB-D; time-of-flight; 3D reconstruction; Kinect v2;

   Abstract : The Kinect v2 is a RGB-D sensor manufactured as a gesture interaction tool for the entertainment console XBOX One. In this thesis we will use it to perform 3D reconstruction and investigate its ability to measure depth. READ MORE

6. 5. Surface Roughness Measurment: Multi-bandFrequency Shift Interferometer based onPolarization Measurement

   University essay from Högskolan i Halmstad/Tillämpad matematik och fysik (MPE-lab)

   Author : Amir Arashlouzadeh; [2014]
   Keywords : ;

   Abstract : Optical measurement techniques have been gaining ground for their vast applications in industry and scientific purposes. These techniques are beneficial comparing to the mechanical methods. Non-intrusive, robust, high accuracy and small measurement volume are some of the advantages of the optical metrology. However, these approaches are expensive. READ MORE
