摘要： Apparatus which can be used in a context of image reconstruction on the basis of projection data produced by an imaging modality, such as computer tomography or magnetic resonance imaging comprises a residual projection data processor (101; 201; 301) and an image reconstruction unit (102; 202; 302). The residual projection data processor (101; 201; 301) is configured to determine residual projection data (Δ g ; Δ g̃ ; Δ ) by cancelling reference projection data ( g ref ; g̃ ref ) from measured projection data ( g obs ; g̃ obs ). The measured projection data ( g obs ; g̃ obs ) represents a measured projection of a test object under examination obtained by an imaging modality. The reference projection data ( g ref ; g̃ ref ) represents a projection of a reference object. The image reconstruction unit (102; 202; 302) is configured to reconstruct a resulting residual image (Δ f ; Δ f̃ ; Δ ) on the basis of the residual projection data (Δ g ; Δ g̃ ; Δ ) by solving an inverse projection transformation problem that links the residual projection data (Δ g ; Δ g̃ ; Δ ) to the resulting residual image (Δ f ; Δ f̃ ; Δ ). The resulting residual image (Δ f ; Δ f̃; Δ ) represents differences between the reference object and the test object under examination. A corresponding method is also described.
