Abstract

A method for scanning a plurality of components of similar design includes providing an imaging beam source, an imaging beam receiver, and a support platform. The method includes disposing the plurality of components on the support platform such that the plurality of components is positioned axi-symmetrically and spaced apart from each other by a first angular range (AR1). The method further includes collecting a first projection of at least one component of the plurality of components at the imaging beam receiver. The first projection includes a combination of a primary image (PI) of the at least one component and a scatter image (SI) of the at least one component. The method further includes collecting a second projection of the at least one component at the imaging beam receiver.

Dependent claims

A method for scanning a plurality of components of similar design, the method comprising the steps of:

providing an imaging beam source, an imaging beam receiver, and a support platform, wherein the imaging beam source and the imaging beam receiver are oppositely disposed to either side of the support platform;
disposing the plurality of components on the support platform such that the plurality of components is positioned axi-symmetrically and spaced apart from each other by a first angular range;
generating, by the imaging beam source, an imaging beam that passes through the plurality of components;
collecting a first projection of at least one component of the plurality of components at the imaging beam receiver, the first projection comprising a combination of a primary image of the at least one component and a scatter image of the at least one component, wherein the primary image comprises a scatter free projection of the at least one component;
collecting a second projection of the at least one component at the imaging beam receiver, the second projection comprising the primary image of the at least one component;
comparing, by a processor, the first projection and the second projection;
generating, by the processor, the scatter image based on the comparison of the first projection and the second projection;
storing, by the processor, the scatter image of the at least one component in a memory;
rotating and/or revolving the support platform by a second angular range relative to the imaging beam source and the imaging beam receiver about one or more axes, wherein the second angular range is equal or greater than the first angular range by at most 20 degrees;
collecting, at different relative angles of rotation and/or revolution of the support platform by the second angular range, further projections of the plurality of components at the imaging beam receiver;
comparing, by the processor, the further projections and the scatter image;
and
generating, by the processor, further primary images of the plurality of components based on the comparison of the further projections and the scatter image, the further primary images comprising corresponding further scatter free projections of the plurality of components.
