摘要： The invention relates to an imaging method for radiologically guiding an instrument during medical interventions on an object (106, 203, 302) comprising: a) providing a first image (501, 602, 706, 806, 906, 1006, 1106) of said object followed by b) providing updated images on-the-fly during the intervention to an operator by measuring an undersampled set of projections of said object (106, 203, 302) and reconstructing said updated image based on changes between said first image (501, 602, 706, 806, 906, 1006, 1106) or an update of said first image (602) and said undersampled set of projections. The invention further relates to particular uses of the method and a system for radiologically guiding medical interventions on an object (106, 203, 302) according to the method, comprising - means to provide a first image (501, 602, 706, 806, 906, 1006, 1106) of the object; - an imaging apparatus measuring undersampled sets of projections; - processing means in communication with the imaging apparatus for providing updated images on-the-fly during the intervention by reconstructing said updated image based on changes between said first image (501, 602, 706, 806, 906, 1006, 1106) or an update of said first image (602) and said undersampled set of projections.
