An embodiment of the present disclosure provides an interface display method, apparatus, device and medium. The interface display method includes: detecting an interface triggering action during a process of displaying a target image by a virtual terminal device; in response to the interface triggering action, determining a target interface that needs to be displayed; detecting a first line-of-sight position corresponding to a line-of-sight of a user in the target image; displaying the target interface at the first line-of-sight position of the target image. By detecting the user's actions and line-of-sight, the display and control of the interface are triggered to solve the problem of low efficiency of interface processing for the extended reality scenario.

Interface display method and apparatus, electronic device and storage medium

Embodiments of the present invention provide a motion tracking method for MR imaging, comprising: exciting an imaging volume of a detected object; shifting a frequency of an FID signal generated by the imaging volume relative to a center frequency as a position of the imaging volume changes; acquiring the FID signal and calculating a frequency shift of the acquired FID signal relative to the center frequency for multiple times; and obtaining a motion trajectory of the detected object in accordance with a change of the frequency shift as a function of time.

Motion tracking method in magnetic resonance imaging, computer program, and storage device

Methods and apparatuses for processing MR signal are disclosed herein. An exemplary method comprises: when acquired K-space signals are amplified, assigning a first amplification gain to signals within a first signal region in the K space, and assigning a second amplification gain to signals within a second signal region in the K space.

Method and apparatus for processing MR signal, and computer program

Systems and methods for suppressing background in time-of-flight (TOF) magnetic resonance angiography (MRA) are disclosed. An exemplary method includes obtaining a first TOF image through a high-resolution acquisition with a saturation band on one side of an imaging slab, obtaining a second TOF image through a low-resolution acquisition with two saturation bands on both sides of the imaging slab, and subtracting the second TOF image from the first TOF image to obtaining a subtraction TOF image. Post processing such as maximum intensity projection (MIP) is performed on the subtraction TOF image.
