Abstract
Systems and methods for image reconstruction are provided. The methods may include obtaining a scout image including a target object, determining a first area and a second area based on the scout image, wherein the second area is located in the first area, obtaining positron emission tomography (PET) data of the first area and first computed tomography (CT) data of the second area, and reconstructing a PET image with respect to the first area based on the PET data and the first CT data.
Claims20
A method implemented on a computing device having at least one processor, the method comprising:
- obtaining, by the at least one processor, a scout image including a target object;
- determining, by the at least one processor, a first area and a second area based on the scout image, wherein the second area is located in the first area;
- obtaining, by the at least one processor, Positron Emission Tomography (PET) data of the first area and first Computed Tomography (CT) data of the second area;
- and
- reconstructing, by the at least one processor, a PET image with respect to the first area based on the PET data and the first CT data.
A system, comprising:
- a storage device including a set of instructions;
- and
- at least one processor configured to communicate with the storage device, wherein when executing the set of instructions, the at least one processor is configured to cause the system to:
- obtain a scout image including a target object;
- determine a first area and a second area based on the scout image, wherein the second area is located in the first area;
- obtain Positron Emission Tomography (PET) data of the first area and first Computed Tomography (CT) data of the second area;
- and
- reconstruct a PET image with respect to the first area based on the PET data and the first CT data.
A non-transitory computer readable medium comprising executable instructions that, when executed by at least one processor, cause the at least one processor to effectuate a method, the method comprising:
- obtaining a scout image including a target object;
- determining a first area and a second area based on the scout image, wherein the second area is located in the first area;
- obtaining Positron Emission Tomography (PET) data of the first area and first Computed Tomography (CT) data of the second area;
- and
- reconstructing a PET image with respect to the first area based on the PET data and the first CT data.
A method implemented on a computing device having at least one processor, the method comprising:
- obtaining, by the at least one processor, a scout image including a target object;
- determining, by the at least one processor, a first area based on the scout image;
- adjusting, by the at least one processor, the first area to the center of a Positron Emission Tomography (PET) scanning field-of-view (FOV);
- obtaining, by the at least one processor, PET data and attenuation information of the first area;
- and
- reconstructing, by the at least one processor, a PET image with respect to the first area based on the PET data and the attenuation information.
