System and method for imaging a subject
A method and system is disclosed for acquiring image data of a subject. The image data can be collected with an imaging system in a selected manner and/or motion. More than one projection may be combined to generate and create a selected view of the subject.
1. A system to create a reconstructed long view image of a subject, comprising:
an O-shaped imaging gantry having enclosed therein a source and a detector both configured to move from at least a first position to a second position to acquire a first image data at the first position relative to the subject and a second image data at the second position relative to the subject;
an image processor configured to execute instructions to:
determine an overlap region between the first image data and the second image data;
generate an intermediate image based on the determined overlap region;
reconstruct the long view image based at least in part on the generated intermediate image; and
output the reconstructed long view image of the subject.
2. The system of claim 1 , further comprising:
an input system to receive an input regarding a portion of the subject to be imaged; and
the image processor configured to execute instructions to select at least the first position and the second position based on the input portion.
3. The system of claim 2 , wherein the waging image processor is configured to execute further instructions to determine a motion profile to move the source and the detector from the first position to the second position.
4. The system of claim 2 , wherein the input includes a length or number of vertebrae to be imaged.
5. The system of claim 1 , further comprising:
a filter configured to filter a beam of x-rays into at least a first beam of x-rays and a second beam of x-rays;
wherein each of the acquired first image data and acquired second image data includes projections from each of the first beam and second beam.
6. The system of claim 5 , wherein the filter includes at least a first slot and a second slot;
wherein the first beam of x-rays passes through the first slot and the second beam of x-rays passes through the second slot.
7. The system of claim 6 , wherein the first slot is formed at an angle of about 5 degrees to about 10 degrees relative to the second slot.
8. The system of claim 5 , wherein the filter includes at least a first slot, a second slot, and a third slot;
wherein the first slot is formed at an angle of about 5 degrees to about 10 degrees relative to the second slot; and
wherein the third slot is formed at an angle of about 5 degrees to about 10 degrees relative to the second slot.
9. The system of claim 1 , further comprising:
a detector moving system configured to move the detector along a path relative to the subject from the first position to the second position;
wherein a plurality of image data portions are operable to be collected at a plurality of intermediate positions between the first position and the second position.
10. The system of claim 9 , wherein the first image data, the second image data, and the plurality of image data portions are acquired based on emitting x-rays from the source.
11. A method of creating a reconstructed long view image of a subject with image data acquired at positions of a source and a detector, comprising:
acquiring a first image data from the source and the detector at a first position relative to the subject;
moving the source and the detector to a second postion:
acquiring a second image data from the source and the detector at the second position relative to the subject;
determining an overlap region between the first image data and the second image data;
generating an intermediate image based on the determined overlap region;
reconstructing the long view image based at least in part on the generated intermediate image; and
outputting the reconstructed long view image of the subject.
12. The method of claim 11 , further comprising:
receiving an input regarding a portion of the subject to be imaged; and
selecting at least the first position and the second position based on the input portion.
13. The method of claim 12 , wherein the input includes a length or number of vertebrae to be imaged.
14. The method of claim 11 , further comprising:
providing a filter to filter a beam of x-rays into at least a first beam of x-rays and a second beam of x-rays;
wherein each of the acquired first image data and acquired second image data includes projections from each of the first beam and second beam.
15. The method of claim 14 , wherein providing the filter includes providing a filter with at least a first slot and a second slot;
wherein the first beam of x-rays passes through the first slot and the second beam of x-rays passes through the second slot.
16. The method of claim 15 , wherein the first slot is formed at an angle of about 5 degrees to about 10 degrees relative to the second slot.
17. The method of claim 14 , wherein providing the filter includes providing a filter with at least a first slot, a second slot, and a third slot;
providing the first slot is formed at an angle of about 5 degrees to about 10 degrees relative to the second slot; and
providing the third slot is formed at an angle of about 5 degrees to about 10 degrees relative to the second slot.
18. The method of claim 11 , further comprising:
moving the source and the detector relative to an O-shaped gantry along a path relative to the subject from the first position to the second position;
collecting a plurality of image data portions at a plurality of intermediate positions between the first position and the second position.
19. The method of claim 18 , wherein the first image data, the second image data, and the plurality of image data portions are acquired based on emitting x-rays from a source.
20. The method of claim 11 , further comprising:
selecting a portion of the subject; and
determining a motion profile to move the source and the detector from the first position to the second position.
