Abstract
A system and method for generating a phase contrast image based on an absorption contrast image are provided. The method may include obtaining an absorption contrast image of a first object. The method may further include obtaining a phase contrast image generation model, wherein the phase contrast image generation model may be associated with at least one sample absorption contrast image and at least one sample phase contrast image of a second object. The method may further include executing the phase contrast image generation model to generate a phase contrast image of the first object based on the absorption contrast image of the first object.
Claims20
A system for generating a phase contrast image, comprising:
- a radioactive scanning source configured to emit radioactive rays toward a first object;
- a detector configured to detect at least some of the radioactive rays emitted from the radioactive scanning source impinging on the detector and to generate a plurality of readings based on the detected radioactive rays;
- a storage device storing a set of instructions, and
- at least one processor configured to communicate with the storage device, wherein when the at least one processor executes the set of instructions, the system is directed to:
- reconstruct an absorption contrast image of the first object based on the plurality of readings;
- obtain a phase contrast image generation model, wherein the phase contrast image generation model is trained based on at least one sample absorption contrast image and at least one sample phase contrast image of at least one second object;
- and
- execute the phase contrast image generation model to generate a phase contrast image of the first object based on the absorption contrast image of the first object.
A method implemented on a computing device having a storage device storing a set of instructions for generating a phase contrast image and at least one processor communicated with the storage device, the method comprising:
- obtaining an absorption contrast image of a first object;
- obtaining a phase contrast image generation model, wherein the phase contrast image generation model is associated with at least one sample absorption contrast image and at least one sample phase contrast image of at least one second object;
- and
- executing the phase contrast image generation model to generate a phase contrast image of the first object based on the absorption contrast image of the first object.
A non-transitory computer readable medium, comprising executable instructions for generating a phase contrast image that, when executed by at least one processor of an electronic device, directs the at least one processor to perform actions comprising:
- obtaining an absorption contrast image of a first object;
- obtaining a phase contrast image generation model, wherein the phase contrast image generation model is associated with at least one sample absorption contrast image and at least one sample phase contrast image of at least one second object;
- and
- executing the phase contrast image generation model to generate a phase contrast image of the first object based on the absorption contrast image of the first object.
