Abstract
A method for reconstructing an object via tomography is provided. The method includes: acquiring a plurality of projections of the object at different angles via an imaging system; backprojecting each projection of the plurality to generate an intermediate image of each projection via at least one processor of the imaging system; and applying a filter to each intermediate image via the at least one processor. The filter is based at least in part on a noise model and an image model.
Claims21
A method for reconstructing an object via tomography comprising:
- acquiring a plurality of projections of the object at different angles via an imaging system;
- backprojecting each projection of the plurality to generate an intermediate image of each projection via at least one processor of the imaging system;
- applying a filter to each intermediate image via the at least one processor prior to completing reconstruction of the object, wherein the reconstruction of the object is based at least in part on each of the filtered intermediate images;
- and
- wherein the filter is based at least in part on a noise model and an image model.
An imaging system for reconstructing an object via tomography comprising:
- at least one processor operative to:
- acquire a plurality of projections of the object at different angles via an imaging device;
- backproject each projection of the plurality to generate an intermediate image of each projection;
- apply a filter to each intermediate image prior to completing reconstruction of the object based at least in part on each of the filtered intermediate images;
- and
- wherein the filter is based at least in part on a noise model and an image model.
A non-transitory computer readable medium storing instructions configured to adapt at least one processor to:
- acquire a plurality of projections of an object at different angles;
- backproject each projection of the plurality to generate an intermediate image of each projection;
- apply a filter to each intermediate image prior to completing reconstruction of the object based at least in part on each of the filtered intermediate images;
- and
- wherein the filter is based at least in part on a noise model and an image model.
