  • Systems and methods for positioning an object
    Patent number: 11727598
    Abstract: A method for positioning an object in a device is provided. The method may include: obtaining, using a capture device, a target image of the object on a table of the device; determining, in the target image, a current mock location associated with a target region of the object to be scanned or treated by the device; determining a distance between a current physical location of the target region and a target position based on the current mock location associated with the target region in the target image and a mapping relation; and/or causing the table to move such that the target region of the object is located at or in the vicinity of the target position, based on the distance.
