Determination of Optimum Planar Imaging Parameters for Small Structures with Diameters Less Than the Resolution of the Gamma Camera
Introduction: The limited spatial resolution of the gamma camera hinders the absolute quantification of planar images of small structures. The imaged structures are affected by partial volume effects (PVEs), which can spread activity and lead to underestimation of the regional distribution. The use of optimum planar parameters reduces the impact of the limited spatial resolution of the gamma c...
متن کاملUse of a compact pixellated gamma camera for small animal pinhole SPECT imaging.
OBJECTIVES Pinhole SPECT which permits in vivo high resolution 3D imaging of physiological functions in small animals facilitates objective assessment of pharmaceutical development and regenerative therapy in pre-clinical trials. For handiness and mobility, the miniature size of the SPECT system is useful. We developed a small animal SPECT system based on a compact high-resolution gamma camera ...
متن کاملA clinical gamma camera-based pinhole collimated system for high resolution small animal SPECT imaging.
The main objective of the present study was to upgrade a clinical gamma camera to obtain high resolution tomographic images of small animal organs. The system is based on a clinical gamma camera to which we have adapted a special-purpose pinhole collimator and a device for positioning and rotating the target based on a computer-controlled step motor. We developed a software tool to reconstruct ...
متن کاملCompton Imaging of MeV Gamma-Rays with the Liquid Xenon Gamma-Ray Imaging Telescope (LXeGRIT)
The Liquid Xenon Gamma-Ray Imaging Telescope (LXeGRIT) is the first realization of a liquid xenon time projection chamber for Compton imaging of MeV γ-ray sources in astrophysics. By measuring the energy deposit and the three spatial coordinates of individual γ-ray scattering points, the location of the source in the sky is inferred with Compton kinematics reconstruction. The angular resolution...
متن کاملSmall animal imaging using a conventional gamma camera exemplified in studies on the striatal dopaminergic system.
BACKGROUND Small animal imaging has recently been the subject of increasing interest and specific imaging devices in particular for positron emission tomography (PET) have been developed. To bypass limitations arising from high acquisition costs and dependence on an in-house cyclotron unit inevitably associated with PET, a conventional gamma camera has been equipped with a pinhole collimator an...
