2. 1. Multidimensional MRI of Cardiac Motion : Acquisition, Reconstruction and Visualization

   Author : Andreas Sigfridsson; Hans Knutsson; Stefan Skare; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; MRI; cardiac; motion; reconstruction; Image analysis; Bildanalys;

   Abstract : Methods for measuring deformation and motion of the human heart in-vivo are crucial in the assessment of cardiac function. Applications ranging from basic physiological research, through early detection of disease to follow-up studies, all benefit from improved methods of measuring the dynamics of the heart. READ MORE

4. 2. Finger Joint Reconstruction with Rib Perichondrium

   Author : Daniel Muder; Torbjörn Vedung; Nils Hailer; Ola Nilsson; Simon Farnebo; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; finger joint; reconstruction; cartilage; transplantation; osteoarthritis; Orthopaedics; Ortopedi;

   Abstract : Difficulties in repairing and reconstructing articular cartilage damaged by trauma or disease remain unsolved and are one of the major challenges confronting orthopedic and hand surgeons in their clinical work. Relevant research has not adequately described the long-term clinical results, nor has it made a direct comparison to implant surgery after finger joint reconstruction with rib perichondrium.

5. 3. Algebraic Reconstruction Methods

   Author : Touraj Nikazad; Tommy Elfving; Constantin Popa; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; iterative methods; image reconstruction; ART; Cimmino; Kaczmarz; Landweber; sequential iteration; simultaneous iteration; block iteration; semi-convergence; relaxation parameters; stopping rules; discrepancy principle; Numerical analysis; Numerisk analys;

   Abstract : Ill-posed sets of linear equations typically arise when discretizing certain types of integral transforms. A well known example is image reconstruction, which can be modeled using the Radon transform. After expanding the solution into a finite series of basis functions a large, sparse and ill-conditioned linear system occurs. READ MORE

6. 4. Automatic Dense Reconstruction from Uncalibrated Video Sequences

   Author : David Nister; KTH; []
   Keywords : Structure from Motion; Calibration; Match Moving; Reconstruction; Video; Computer Vision; Auto-calibration; Augmented Reality; Virtual Reality; Image-based Rendering; Visualisation; Camera Calibration; Motion Estimation;

   Abstract : This thesis describes a system that completely automaticallybuilds a three-dimensional model of a scene given a sequence ofimages of the scene. The system also estimates the internalparameters of the camera and the poses from where the originalimages were taken. READ MORE

7. 5. Experimental Bladder Reconstruction

   Author : Hans Frederiksen; Urologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Urology; smooth muscle; detrusor; matrix; nerves; subtotal cystectomy; bladder regeneration; enterocystoplasty; nephrology; Urologi; nefrologi;

   Abstract : Reduced urinary bladder capacity is a clinically significant problem. The surgical methods that have been available to treat this, such as urinary diversion or surgically augmenting the bladder by incorporation of intestinal segments, all have serious drawbacks. READ MORE
