To provide a medical processing system capable of arbitrarily setting the data amount of operation data.

A controller 10 is provided with a level setting button 13 setting the level of the data amount of the operation data (operation log) indicating the data related to the operation of an X-ray diagnostic apparatus 20. The side of the controller 10 is provided with the level setting button 13 to arbitrarily set the data amount of the operation log. That is to say, this system can change the setting in the mid-course and easily change the setting compared with a case of setting the level of the data amount in a remote area such as a maintenance PC 30.
