The present disclosure is related to systems and methods for subject positioning. The method includes generating a reference subject model of a subject to be scanned by a medical device based on feature information of the subject and a scan protocol of the subject. The method includes generating a target subject model by performing one or more rendering operations on the reference subject model based on at least one rendering parameter associated with an image capturing device. The method includes generating a positioning result by integrating the target subject model with image data related to a scan scene of the subject captured by the image capturing device. The method includes positioning the subject based on the positioning result.

Systems and methods for subject positioning

A simultaneous phase-shift point diffraction interferometer and method for detecting wave aberration. The interferometer comprises an ideal spherical wave generation module, an optical system to be measured, an image plane mask, a polarization phase shift module, a two-dimensional polarization imaging photodetector and a data processing unit. Single photodetector is adopted to realize simultaneous detection of more than three phase shift interference patterns, and has the advantages that environmental interference suppression, a flexible optical path, high measurement accuracy, and calibration of system errors of the interferometer may be realized.

The present disclosure relates to systems and methods for image storage. The methods may include obtaining a first image of a subject. The methods may further include obtaining a second image of the subject. The second image may include scan status information of the subject. The scan status information may be associated with a status of the subject when the first image is acquired. And The methods may also include storing the second image correspondingly with the first image.
