Abstract: In an embodiment, a children face alert system is provided for use with a smart device with a display screen. A neural network model trained with dataset images with embedded distance information can run in the background of the smart device. When receiving a captured image frame of the face of a child using the smart device, the neural network model can determine that the captured image frame is from a child, and further determine whether the face of the child is within a predetermined distance to the display screen based on a size of the face on the captured image frame. If the face is within the predetermined distance, the smart device can display an alert that the face of the child is too close to the display screen and pause one or more user applications until the child's face moves outside of the predetermined distance.

Abstract: 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.
