METHOD AND DEVICE FOR APPLICATION OF TIME-OF-FLIGHT INFORMATION FOR DETECTION AND INTRODUCTION OF CORRECTIONS FOR MOVEMENT IN SCANOGRAMS Russian patent published in 2015 - IPC A61B6/03 G06K9/00 

FIELD: medicine.

SUBSTANCE: invention relates to medical equipment, namely to means of obtaining movement images, for instance, y means of positron-emission tomography. Method of detecting movement in the process of obtaining images by means of medical system contains stages at which subject's image is obtained in order to form data of obtaining images, which include time-of-flight data, time-of-flight data are controlled in the process of obtaining images, time-of-flight data are analysed to detect movement. Method of estimating respiratory movement in data of obtaining images contains stages at which subject's electrocardiogram is additionally obtained in the process of obtaining images and used to gating image data in order to form cardiosynchronised data, after which cardiosynchronised data are divided into time subintervals in order to obtain respiration-synchronised heart images, centre of activity is determined in respiration-synchronised heart images and centres of activity in different respiration-synchronised heart images are compared in order to form vectors of respiratory movement. In the second version of evaluation method electrocardiogram is used to divide data of obtaining images into cardiac cycles, centre of activity in cardiac cycles is determined and centres of activity in different cardiac cycles are compared in order to form vectors of respiratory movement.

EFFECT: application of invention makes it possible to reduce probability of errors in synchronisation of examination with respiratory movements.
