Title
(EN) RADIATION TOMOGRAPH
(FR) TOMOGRAPHE A RADIATIONS
Abstract
(EN) A radiation tomograph giving an image of good quality based upon view interlacing without making complex the rotation control of the gantry and the sampling control of the scan data. Sampling points of a number of N.M-1 (where M and N are positive integers) are provided around a subject to be inspected, and the scanning making a round is continuously carried out M times over every M-1 sampling points to collect the scan data.
(FR) Tomographe à radiations produisant une image de bonne qualité par un procédé d'entrelacement d'images simplifiant la commande de rotation du châssis et la commande d'échantillonnage des données de balayage. Une série de N.M-1. d'échantillonnages (où M et N sont des entiers positifs) sont disposés autour d'un sujet à examiner, et l'exploration circulaire est effectuée en continu M fois tous les M-1 points d'échantillonnages pour collecter les données de balayage.
