1. A method for treating an object, comprising:
imaging, using an imaging device, an object fixed on a positioning device to obtain a plan image of the object;
generating, based on the plan image of the object, information of a region of interest (ROI) of the object;
generating, based on the information of the ROI, a treatment plan, the treatment plan including a plan isocenter on the plan image, the plan isocenter referring to a point defined in the plan image and the point defined in the plan image representing a point of the object located at a machine isocenter of a treatment device when the object is treated; and
treating, based on the treatment plan, a target portion of the object using the treatment device, the object being fixed on the positioning device from a moment that the object is started to be imaged by the imaging device to obtain the plan image to an end of the treatment of the target portion.
