  1. 1. Evaluation of the Impact of X-ray Tube Voltage and Filter Thickness on the Performance of Spectral Photon-Counting Detectors

    University essay from KTH/Medicinteknik och hälsosystem

    Author : Cassandra Mannila; Marcus Larsson; [2021]
    Keywords : Photon Counting Detectors; X-ray Tube Voltage; Filter Thickness; Detective Quantum Efficiency; Optimizing; Fotonräknande detektorer; Rörspänning; Filtertjocklek; DQE; Optimering;

    Abstract : During the past years photon-counting detectors (PCDs) have emerged as an alternative to conventional energy-integrating detectors and may significantly improve the standard of care for computed tomography (CT). There are two main alternatives for the material of the detector: cadmium telluride (CdTe) and silicon (Si). READ MORE

  3. 2. Quality Assurance of Intra-oral X-ray Images

    University essay from Umeå universitet/Radiofysik

    Author : Dieudonne Diba Daba; [2020]
    Keywords : Intraoral; X-rays; Intraoral X-rays; Quality assurance; Quality control; image quality; dental; Intraoral; Röntgen; Kvalitetskontroll; Intraoral röntgen; tandvård;

    Abstract : Dental radiography is one of the most frequent types of diagnostic radiological investigations performed. The equipment and techniques used are constantly evolving. READ MORE

  4. 3. Micro-CT for small animal imaging : Optimization of the tube voltage for low-contrast imaging

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

    Author : Massimo Terrin; [2015]
    Keywords : ;

    Abstract : This master thesis evaluated the optimal tube voltage for low-contrast imaging of a micro-CT system (intended for small animal imaging) built at the School of Technology and Health (STH) of the Royal Institute of Technology (KTH). The main goal of this work was to calibrate the above-mentioned device (composed moreover by a Hamamatsu microfocus L10951-01 X-ray tube, a CMOS flat panel Hamamatsu C7942CA-22 and using a Cone-Beam CT reconstruction algorithm) for obtaining the best imaging of low-contrast structures.

  5. 4. Optimization of Dual Energy data acquisition using CdTe-detectors with electronic spectrum splitting

    University essay from Tekniska högskolan; Biomedicinsk instrumentteknik

    Author : Charlotte Eriksson; [2013]
    Keywords : Dual Energy; CdTe; X-ray; photon-counting detectors;

    Abstract : Dual energy imaging has made it possible to enhance contrast in medical images using images containing different energy information, by combining low and high energy images. Dual energy data can either be acquired using double exposures or splitting the energy spectrum into two images using one exposure. READ MORE

  6. 5. Finding 3D Teeth Positions by Using 2D Uncalibrated Dental X-ray Images

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Bitra Sridhar; Dandey Venkata Prasad; [2010]
    Keywords : Dental X-ray; 3D Position; Simulation; Fourier transform;

    Abstract : In Dental Radiology very often several radiographs (uncalibrated in position) are taken from the same person. The radiographs do not provide the depth details, and there is often requirement of three dimensional (3D) data to achieve better diagnosis by radiologist. READ MORE
