Setting device, setting method, and setting program

A setting method executed by a processor, the setting method comprising:

• acquiring imaging part information indicating an imaging part of a subject whose radiographic image is captured by radiation emitted from a radiation emitting device;
• acquiring body thickness information indicating a body thickness of the subject in a direction in which the radiation is transmitted;
• acquiring condition information indicating that an imaging condition set in the radiation emitting device is one of a first condition in which a tube voltage value is a fixed value and a mAs value is a variable value, a second condition in which the tube voltage value is a variable value and the mAs value is a fixed value or a third condition in which the tube voltage value is a variable value and the mAs value is a variable value;
• and
• deriving a set value of the tube voltage and a set value of the mAs value of the radiation emitting device for emitting the radiation such that a dose of the radiation transmitted through the imaging part is the same as a dose at a reference body thickness, based on a set of parameters including the imaging part indicated by the imaging part information and the body thickness indicated by the body thickness information, under each of the first condition, the second condition and the third condition;
• and
• for a particular derivation of the set value of the tube voltage and the set value of the mAs value, setting one of the first condition, the second condition or the third condition, as a set condition, and then deriving the set value of the tube voltage and the set value of the mAs value under the set condition.

A non-transitory computer-readable storage medium storing a setting program that causes a processor to execute a process comprising:

• acquiring imaging part information indicating an imaging part of a subject whose radiographic image is captured by radiation emitted from a radiation emitting device;
• acquiring body thickness information indicating a body thickness of the subject in a direction in which the radiation is transmitted;
• acquiring condition information indicating that an imaging condition set in the radiation emitting device is one of a first condition in which a tube voltage value is a fixed value and a mAs value is a variable value, a second condition in which the tube voltage value is a variable value and the mAs value is a fixed value or a third condition in which the tube voltage value is a variable value and the mAs value is a variable value;
