Super resolution in positron emission tomography imaging using ultrafast ultrasound imaging |
| abstract |
An imaging method including:n a) acquiring N successive positron emission tomography (PET) low resolution images Γ 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 M i 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 H n+1 obtained by applying several correction iterations to a current estimated high resolution image H n , n being the number of iterations, starting from an initial estimated high resolution image H 1 of the object, each correction iteration including at least: i) warping the estimated high resolution image H n using the motion vector fields M i to determine a set of low resolution reference images L n i ; ii) determining a differential image Di by difference between each PET image Γ i and the corresponding low resolution reference image L n i ; iii) warping back the differential images Di using the motion vector fields M i and averaging the N warped back differential images to obtain a high resolution differential image; iv) determining the high resolution image H n+1 by correcting the high resolution image H n using the high resolution differential image; d) applying the motion vector fields M i of each UUI image Ui to the final high resolution image H. |
