摘要: For the purpose of enabling reduction exposure dose, in an X-ray controlling method for X-ray imaging apparatus producing image based on detected signals, upper limit dose to a subject to be imaged is set (602), and tube current is modulated so that does not exceed (606 - 610). The modulation achieved by finding exposure dose predicted value based protocol, modifying a tube current protocol when exceeds the limit.
