Then, the fixture identification information reading unit 102 displays the fixture identification information and the setting condition identification information “arm stand_left arm / angle 15 °” in the third column of the scan result (step S03, FIG. 9). reference). Subsequently, the collation processing unit 103 determines whether or not the fixture identification information and the setting condition identification information “arm stand_left arm / angle 15 °”, which are scan results, are included in the setup table (step S04). .. In this case, since the fixture identification information and the setting condition identification information "arm stand_left arm / angle 15 °" which are the scan results are included in the setup table, the collation processing unit 103 sets the determination result "○" to "○". It is displayed in the "determination result" column (see step S05, FIG. 9).

Subsequently, the operator arranges the patient-specific fixing pillow 31 defined in the treatment plan on the bed 3.
When the arrangement of the fixing pillow 31 is completed, the operator holds the reader 15 over the barcode 30A attached to the fixing pillow 31 and reads the fixture identification information (step S02). Then, the fixture identification information reading unit 102 displays the fixture identification information “fixing pillow_123” in the fourth column of the scan result (see step S03, FIG. 9). Subsequently, the collation processing unit 103 determines whether or not the fixture identification information “fixing pillow_123”, which is the scan result, is included in the setup table (step S04). In this case, since the fixture identification information "fixing pillow_123" which is the scan result is included in the setup table, the collation processing unit 103 displays the determination result "○" in the "determination result" column ( Step S05, see FIG. 9).

Subsequently, the operator arranges the patient-specific knee fixture 33 defined in the treatment plan on the bed 3.
When the arrangement of the knee fixture 33 is completed, the operator holds the reader 15 over the barcode 30A attached to the knee fixture 33 to read the fixture identification information (step S02). Then, the fixture identification information reading unit 102 displays the fixture identification information “knee fixture_023” in the fifth column of the scan result (see step S03, FIG. 9). Subsequently, the collation processing unit 103 determines whether or not the fixture identification information “knee fixture_023”, which is the scan result, is included in the setup table (step S04). In this case, since the fixture identification information "knee fixture_023" which is the scan result is not included in the setup table, the collation processing unit 103 displays the determination result "x" in the "determination result" column ( Step S05, see FIG. 9).

As described above, the operator reads the barcode 30A attached to each fixture 30 each time the necessary fixtures 30 are arranged and adjusted (set) in the setup work. Then, the radiation therapy setup device 10 immediately determines whether or not the fixture 30 is the correct fixture (and whether or not the setting conditions are correct) for the patient performing the radiotherapy.
