| 简介 |
FIELD : physics.
SUBSTANCE : system comprises the following : the system contains : input device (14) for reception of radionuclide image and morphological images of an object, processing unit (15) configured for : processing of morphological images for obtaining the information on rare movements of an object, obtaining of reduced series of measurements from fast detection of signals along the parallel bundle of rays, parametrisation and adaptation of the motion model for calculation of motion of a patient from the reduced series of measurements, use of the information on rare motions and the motion model for obtaining the information on estimated motion of an object, generation of the time-dependent attenuation scale, on the basis of the information on the estimated movement, generation of the radionuclide image with the movement correction on the basis of the obtained radionuclide image and the time-dependent attenuation scale, and the output device (17) for output of reconstructed radionuclide image.
EFFECT : providing of obtaining of high-quality radionuclide image of a moving object.
