  • Slit-slat collimation
    Patent number: 7831024
    Abstract: This invention is directed to a collimator and collimation techniques. Specifically, the invention is directed to a collimator and method for collimation wherein the collimator combines the resolution and sensitivity properties of pinhole Single Photon Emission Computed Tomography (SPECT) imaging with the 2D complete-sampling properties of fan-beam collimators.
    Type: Grant

  • Three dimensional image reconstruction for a positron emission tomograph
    Patent number: 5331553
    Abstract: Images are reconstructed using multi-slice rebinning of raw data to create a stack of two-dimensional data sets. A three-dimensional image is reconstructed slice-by-slice from the data sets and the rebinned data is axially filtered to reduce blurring resulting from the rebinning, the filtering being performed either before or after reconstruction of the three-dimensional image.
