Claim One:
1. A method for generating a processed image of a cross-section through a body, comprising the steps of: disposing the body between a combination of a source of radiation and an associated detector, such that a beam of radiation from said source impinges angularly on said body and passes through to said detector; effecting relative rotational motion between said beam and said body such that a principal plane of interest in said body remains substantially in focus during said relative rotational motion; deriving from the detector, at different rotational positions, a series of frames of electronic video signals that represent images of the radiation transmission characteristics of the body at a series of successive times; temporally filtering said series of frames by combining successive frames of the series with a weighting for each combination that depends on when the frames being combined occur in time with respect to each other; and displaying the temporally filtered series of frames.
