In order to reduce a burden on an operator for setting scanning conditions by configuring so that an index value can be estimated immediately by setting a parameter and the value from among scanning conditions, the present invention provides a medical image scanning apparatus that acquires and displays tomographic images of an object and is characterized by comprising: an index value calculation unit that calculates an index value based on each parameter value of scanning conditions a scale setting unit that sets a scale of each parameter axis according to the calculated index value and a display control unit that displays a relational diagram including a graphic indicating the magnitude of the calculated index value and each parameter axis having the set scale.
