  • Super resolution in positron emission tomography imaging using ultrafast ultrasound imaging
    Patent number: 11940578
    Abstract: An imaging method including: a) acquiring N successive positron emission tomography (PET) low resolution images ?i and simultaneously, N successive Ultrafast Ultrasound Imaging (UUI) images Ui of a moving object; b) determining from each UUI image Ui, the motion vector fields Mi that corresponds to the spatio-temporal geometrical transformation of the motion of the object; c) obtaining a final estimated high resolution image H of the object by iterative determination of a high resolution image Hn+1 obtained by applying several correction iterations to a current estimated high resolution image Hn, n being the number of iterations, starting from an initial estimated high resolution image H1 of the object, each correction iteration including at least: i) warping the estimated high resolution image Hn using the motion vector fields Mi to determine a set of low resolution reference images Lni; ii) determining a differential image Di by difference between each PET image ?i and the corresponding low resolution re
