Problems solved by technology

Phase-contrast imaging can currently be performed using phase-contrast imaging equipment, which is expensive and inconvenient
In addition, compared with ordinary X-ray imaging equipment, the current phase contrast imaging equipment usually has a smaller field of view (FOV, field of view), so the size of the generated phase contrast image is limited

Abstract

The present application provides a system and method for generating a phase contrast image based on an absorption contrast image. The method may include acquiring an absorption contrast image of the first object. The method may further include acquiring a phase contrast image generation model, wherein the phase contrast image generation model may be associated with at least one absorption contrastimage sample of the second object and at least one phase contrast image sample of the 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.

Description

technical field [0001] The present application relates to an X-ray imaging method and system, in particular to a method and system for generating a phase contrast image based on an absorption contrast image. Background technique [0002] X-ray imaging is often used in medical diagnosis to reveal the condition of a patient's organs or tissues. Absorption contrast imaging is a simple and commonly used X-ray imaging technique that typically produces high-quality images of hard tissues and low-quality images of soft tissues. A different X-ray imaging technique, phase-contrast imaging, can produce soft tissue images with better quality. Currently, phase contrast imaging can be performed using phase contrast imaging equipment, which is expensive and inconvenient. In addition, compared with ordinary X-ray imaging equipment, current phase contrast imaging equipment usually has a smaller field of view (FOV, field of view), so that the size of the generated phase contrast image is l...
