  • Single photon emission computed tomography imaging with a spinning parallel-slat collimator
    Patent number: 10795033
    Abstract: A method and a system for single photon emission computed tomography (SPECT) imaging capable of performing a rapid acquisition of imaging data. The SPECT imaging system, placed at a fixed radial distance from the center of an object being imaged, includes a gamma detector and a collimator. The collimator, mounted on the gamma detector, includes a plurality of parallel slats, each perpendicular to the surface of the gamma detector. The method implemented by this system rapidly reconstructs a high-resolution and high-sensitivity image.
    Type: Grant
    Filed: March 13, 2018
    Date of Patent: October 6, 2020
    Inventors: Hojjat Mahani, Mohammad Reza Ay, Saeed Sarkar, Mohammad Hossein Farahani
  • Positron range reduction in positron emission tomography imaging
    Patent number: 10295680
    Abstract: Methods and systems are disclosed, including a method for confining an annihilation range of a positron, from a plurality of positrons emitted from an object being imaged in a positron emission tomography (PET) imaging system. Confining the annihilation includes applying a stochastic multidimensional time varying magnetic field on the positron. Optionally, the stochastic multidimensional time varying magnetic field includes components in each of three dimensions.
