In this case, the values of the above scan parameters are basically set according to the examination order information from the doctor. However, since the tube voltage kV and the tube current mA of the X-ray tube are related to the physique of the subject, the discretion of an engineer is required to obtain a better CT image. Therefore, the technician can refer to the information relating to the physical constitution of the subject. Alternatively, if the subject has an imaging history in the past, it is possible to refer to the imaging conditions (tube voltage kV, tube current mA) at that time. Furthermore, considering the dose of the subject (the frequency of past examinations),
