  2. 6. Patient Positioning in Radiotherapy Using Body Surface Scanning

    Author : Kenneth Wikström; Anders Ahnesjö; Sven Bäck; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radiotherapy; positioning; body surface; laser scanning; cancer; SGRT; ITV; lung cancer; surrogate; tumour motion; 4DCT; Medicinsk radiofysik; Medical Radiophysics;

    Abstract : External radiotherapy uses ionising radiation to damage the DNA of the tumour cells and thereby inhibit their uncontrolled proliferation. The technical development regarding imaging and visualisation for radiotherapy has increased considerably during the last decades. READ MORE

  4. 7. An industrial robot as carrier of a laser profile scanner : motion control, data capturing and path planning

    Author : Sören Larsson; Johan Kjellander; Wolfgang H. Koch; Örebro universitet; []
    Keywords : Geometric reverse engineering; Laser scanning; Industrial robot; Path planning; CAD; 3D measurement systems; Mechanical engineering; Maskinteknik; TECHNOLOGY; TEKNIKVETENSKAP; Mechanical Engineering; Maskinteknik;

    Abstract : Geometric Reverse Engineering (RE) is concerned with the problem of creating CAD-models of real objects by measuring point data from their surfaces. In the aim of creating a fully automatic RE system there is a need to automate also the measuring process. READ MORE

  5. 8. Application of Laser Techniques for Combustion Studies

    Author : Marcus Aldén; Fysiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Keywords: Laser-induced fluorescence; Raman Spectroscopy; Coherent anti-Stokes Raman Scattering CARS ; flames; laserspectroscopy; dye laser; lidar; remote sensing; combustion; air pollution; radicals; optical multichannel analyzer.; Fysicumarkivet A:1983:Aldén;

    Abstract : The aim for this work has been to increase the applicability of laser spectroscopy techniques for studies of combustion processes, both what regards in-flame experiments, exhaust-gas analysis and remote sensing of the atmosphere. Raman spectroscopy has been used for analysis of exhaust gases from flames, model fires of wood and for inflame measurements. READ MORE

  6. 9. Modeling rating curves from close-range remote sensing data : Application of laser and acoustic ranging instruments for capturing stream channel topography

    Author : Norris Lam; Steve W. Lyon; Jason W. Kean; Ida Westerberg; Helle Skånes; James Brasington; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; laser scanning; acoustic Doppler current profiler; hydraulic modeling; rating curves; Sweden; Physical Geography; naturgeografi;

    Abstract : A rating curve provides a functional relationship between water height (i.e. stage) and discharge at a specified cross-section in a river. Used in combination with a time series of stage, rating curves become one of the central components for generating continuous records of streamflow. READ MORE

  7. 10. Development of Time Resolved Laser Imaging Techniques for Studies of Turbulent Reacting Flows

    Author : Johan Hult; Förbränningsfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Electronics and Electrical technology; Laserteknik; Elektronik och elektroteknik; Laser technology; Fysik; Physics; Three-dimensional; Laser Diagnostics; High speed; Fysicumarkivet A:2002:Hult;

    Abstract : In the present thesis the development and application of a novel laser diagnostic system for high speed spectroscopic imaging of turbulent combustion phenomena is presented. The system is capable of recording sequences of up to 8 images with a separation between consecutive images as short as microseconds. READ MORE
