    Abstract: According to one embodiment, a medical device operation method includes a monitoring step and an application step. In the monitoring step, a monitoring apparatus executes first CT imaging on a treatment target person into which a first drug particle with a suppressed onset of a treatment effect is introduced, and monitors an accumulation of the first drug particles in a tissue, based on spectral information acquired by the first CT imaging. In the application step, an application apparatus applies an action for exerting the treatment effect of the first drug particle to the first drug particle accumulating in the tissue, by using as a trigger an event that the accumulation of the first drug particles in the tissue satisfies an objective condition.
