1. A dose adjustment device mountable to a diagnostic radiation apparatus, the dose adjustment device comprising:
a housing;
a power supply comprising battery;
a multi-leaf collimator configured to adjust transmittance for a portion in an irradiation area of diagnostic radiation;
an actuator configured to individually adjust positions of single-leaves included in the multi-leaf collimator;
a communication module configured to communicate with an outside; and
a controller configured to control the actuator so that the transmittance for each portion in the irradiation area of the diagnostic radiation can be adjusted based on a signal received from the communication module,
wherein the controller operates the actuator using the battery integrated into the dose adjustment device.
