A treatment preparation apparatus includes a peripheral simulator that simulates a peripheral portion of the object after the object is disposed in the irradiation chamber, when fixing the relative position of the object to the irradiation target in the preparation chamber. Therefore, when positioning the patient in the preparation chamber, by using the peripheral simulator, the positioning can be performed in consideration of the peripheral portion of the object in the irradiation chamber. That is, in the preparation chamber, the patient can be fixed at a position in the irradiation chamber where shift is unlikely to occur, considering the positional relationship between the patient and the peripheral portion. From the above, when positioning the patient in the preparation chamber, it is possible to position the patient at a position that shift is unlikely to occur during irradiation.
