Abstract
In a tomodensitometric image reconstruction process the detectors 11 of the tomodensitometer are offset by .DELTA.d/4 (.DELTA.d being the pitch of the detectors), and reconstruction is performed during one complete revolution of the detector assembly, the linear absorption values being weighed by a coefficient .alpha. and an equivalent number of intermediary values being produced by summing each time two successive juxtaposed real values (summation device 20) and weighing the resulting sum by a coefficient .beta./2 prior reconstructing the image on the basis of all these data.
