A method may include obtaining a feedback or a reference value of a tube voltage applied to a radiation source of a radiation device for generating radiation rays. The method may also include determining, based on the feedback or the reference value of the tube voltage, a specific value of a focusing parameter associated with a focusing device of the radiation device. The method may further include causing the focusing device to shape a focus of the radiation rays according to the determined value of the focusing parameter. The focus of the radiation rays may satisfy an operational constraint under the specific value of the focusing parameter.

Embodiments of the invention provide an intelligent device and a method for controlling a boot screen of the intelligent device, applicable to the intelligent device supporting video hardware decompression. The method comprises steps of: completing hardware initialization operation, and storing a preset image in the first storage area, thereby enabling the image layer to display the preset image; starting a system kernel which controls the video driver module, and starting the video layer through the video driver module; reading the corresponding preset image in the first storage area, converting the preset image into video data, and writing the video data into the second storage area, thereby enabling the video layer to display the video data; and starting an application access to the system. During the whole startup process of the intelligent device, the contents displayed on a screen are all seamlessly connected, so that a phenomenon of black screen does not occur.
