Claims24
A computerized tomography (CT) scanner comprising:
- a source defining an imaging plane;
- and
- a filter including a first filter portion including a first material, a second filter portion including a second material, and a third filter portion including the first material and the second material;
- wherein the third filter portion includes alternating columns of the first material and the second material, wherein each column intersects the imaging plane;
- and
- wherein the filter is movable with respect to the source to align any one of the first filter portion, the second filter portion, and the third filter portion with the imaging plane.

A computerized tomography (CT) scanner comprising:
- a source defining an imaging plane;
- and
- a filter including a first filter portion including a first material, a second filter portion including a second material, and a third filter portion including the first material and the second material;
- wherein the first material has a first mass attenuation coefficient within a range of 0.1 cm2/g to 200 cm2/g corresponding to an excitation within a range of 10 to 200 kVp, and the second material has a second mass attenuation coefficient corresponding to the excitation different than the first mass attenuation coefficient;
- and
- wherein the filter is movable with respect to the source to align any one of the first filter portion, the second filter portion, and the third filter portion with the imaging plane.

- wherein the filter is movable with respect to the source to align any one of the first filter portion, the second filter portion, and the third filter portion with the imaging plane.
3 more elements
A computerized tomography (CT) scanner comprising:
- a source defining an imaging plane;
- and
- a filter including a first filter portion including a first material, a second filter portion including a second material, and a third filter portion including the first material and the second material;
- wherein the third filter portion is positioned between the first filter portion and the second filter portion;
- and
- wherein the filter is movable with respect to the source to align any one of the first filter portion, the second filter portion, and the third filter portion with the imaging plane.
3 more elements
A computerized tomography (CT) scanner comprising:
- a source defining an imaging plane;
- and
- a filter including a first filter portion including a first material, a second filter portion including a second material, and a third filter portion including the first material and the second material;
- wherein the first filter portion at least partially overlaps the third filter portion, and the second filter portion at least partially overlaps the third filter portion;
- and
- wherein the filter is movable with respect to the source to align any one of the first filter portion, the second filter portion, and the third filter portion with the imaging plane.
