Abstract
The present disclosure provides a system and method for image reconstruction and processing. The method may include obtaining image data of an object acquired by an imaging device. The method may include determining one or more regions of interest (ROIs) of the object. The method may also include determining, based on each ROI of the one or more ROIs, a target portion of the image data corresponding to the ROI among the image data. The method may further include reconstructing, based on the target portion of the image data, one or more images of the ROI.
Claims20
A system, comprising:
- at least one storage device storing executable instructions, and
- at least one processor in communication with the at least one storage device, when executing the executable instructions, causing the system to perform operations including:
- obtaining image data of an object acquired by an imaging device, wherein the image data relates to multiple lines of response (LORs);
- determining one or more regions of interest (ROIs) of the object;
- determining, based on each ROI of the one or more ROIs, a target portion of the image data corresponding to the ROI among the image data, wherein the target portion of the image data corresponding to the ROI relates to target LORs among the multiple LORs that traverse a reconstructed axial field of view (AFOV) of the ROI;
- and
- reconstructing, based on the target portion of the image data, one or more images of the ROI.
A method, implemented on a computing device including at least one processor and at least one storage medium, and a communication platform connected to a network, the method comprising:
- obtaining image data of an object acquired by an imaging device, wherein the image data relates to multiple lines of response (LORs);
- determining one or more regions of interest (ROIs) of the object;
- determining, based on each ROI of the one or more ROIs, a target portion of the image data corresponding to the ROI among the image data, wherein the target portion of the image data corresponding to the ROI relates to target LORs among the multiple LORs that traverse a reconstructed axial field of view (AFOV) of the ROI;
- and
- reconstructing, based on the target portion of the image data, one or more images of the ROI.
A non-transitory computer readable medium, comprising executable instructions that, when executed by at least one processor, direct the at least one processor to perform a method, the method comprising:
- obtaining image data of an object acquired by an imaging device, wherein the image data relates to multiple lines of response (LORs);
- determining one or more regions of interest (ROIs) of the object;
- determining, based on each ROI of the one or more ROIs, a target portion of the image data corresponding to the ROI among the image data, wherein the target portion of the image data corresponding to the ROI relates to target LORs among the multiple LORs that traverse a reconstructed axial field of view (AFOV) of the ROI;
- and
- reconstructing, based on the target portion of the image data, one or more images of the ROI.
