摘要： A scanning table is provided to measure a patient's weight accurately. The scanning table may include a table body, for supporting a human body; a lifting system, for driving the table body to go up and down; and a force-measuring component connected with the lifting system, for measuring a support force which is imposed on the table body by the lifting system. Because the support force to the table body by the lifting system is related to positions of a patient and the table body. When the lifting system is connected with the force-measuring component, a force measured by the force-measuring component can reflect the patient's weight accurately and truly. The force-measuring component can measure a change of the support force, which is combined with related data of the table body to obtain the patient's weight. Therefore, the measurement accuracy can be improved.
