  1. 16. Uneven Image Point Distribution in Camera Pre-Calibration and its Eects on 3D Reconstruction Errors

    University essay from Umeå universitet/Institutionen för datavetenskap

    Author : Niklas Fries; [2017]
    Keywords : ;

    Abstract : In camera pre-calibration, images of a calibration object are commonly used to determine the internal geometry of a camera. The calibration imaging is often optimized to have the calibration object cover as large image area as possible. This is likely to yield a larger concentration of measured image points near the center of the image sensor. READ MORE

  3. 17. Advanced Technologies for Detection of Cryptosporidum parvum in Drinking water: capture and detection using Microfluidic devices and Imaging Flow Cytometer

    University essay from KTH/Mark- och vattenteknik

    Author : Safa Karimi Molan; [2017]
    Keywords : Drinking water treatment; pathogen detection; Cryptosporidium; microfluidic devices; Imaging flow Cytometry; Capture efficiency;

    Abstract : Protecting drinking water supplies from pathogens such as Cryptosporidium parvum is a major concern for water treatment plants worldwide. The sensitivity and specificity of current detection methods are largely determined by the effectiveness of the concentration and separation methods used. READ MORE

  4. 18. CUDA Accelerated 3D Non-rigid Diffeomorphic Registration

    University essay from KTH/Skolan för teknik och hälsa (STH)

    Author : An Qu; [2017]
    Keywords : diffeopmorphic demons; non-rigid image registration; parallel programming; GPGPU; IGI;

    Abstract : Advances of magnetic resonance imaging (MRI) techniques enable visualguidance to identify the anatomical target of interest during the image guidedintervention(IGI). Non-rigid image registration is one of the crucial techniques,aligning the target tissue with the MRI preoperative image volumes. READ MORE

  5. 19. Optical Imaging and Spectroscopy of Airborne Nanowires

    University essay from Lunds universitet/Fysiska institutionen

    Author : Eleni Gompou; [2017]
    Keywords : Physics and Astronomy;

    Abstract : Semiconductor nanowires are the potential base for building many future devices like solar cells and light emitting diodes. To reach the level of commercialization of such devices, mass production of NWs at low cost with reproducible high quality properties in terms of crystallinity, material and dimensions is a prerequisite.

  6. 20. Evaluation of differences in attenuation pattern for myocardial perfusion scintigraphy between CZT and conventional gamma cameras

    University essay from Lunds universitet/Medicinsk strålningsfysik, Lund; Lunds universitet/Sjukhusfysikerutbildningen

    Author : Elin Martinsson; [2016]
    Keywords : Medicine and Health Sciences;

    Abstract : The new CZT camera has a different technology compared to conventional scintillation gamma cameras. The CZT camera have pinholes instead of parallel hole collimators, a static gantry instead of a rotating one and detection material made of a semiconductor in- stead of a scintillation crystal.
