BRIEF DESCRIPTION OF THE DRAWINGS FIG. It should be noted that the present invention is not limited by this.

FIG. 1 is an overall configuration diagram showing an embodiment of a scan protocol setting device for a CT scanner according to the present invention. The scan protocol setting device 1 includes a patient information input device 2, an examination site input device 3, a file storage device 4, and a scan protocol selection device 5. The patient information input device 2 transmits the patient information (patient ID, name, age, etc.) input by the operator to the CT scanner T. Further, the age AGE of the patient is transmitted to the scan protocol selection device 5. The examination region input device 3 transmits the examination region selected by the operator to the CT scanner T and the scan protocol selection device 5.

The file storage device 4 stores a scan protocol file 4a. The scan protocol file 4a stores an adult scan protocol and a pediatric scan protocol. For example, the X-ray irradiation intensity differs between the adult scan protocol and the pediatric scan protocol. The file storage device 4 stores a selection criterion parameter file 4b. The selection criterion parameter file 4b stores an age threshold value determined for each examination region. For example,
If the examination site is the head, there is no difference in the scan protocol between adults and children, so the age threshold is set to 0 years. On the other hand, for the chest, for example, the age is 10 years.

The scan protocol selecting device 5 extracts the age threshold corresponding to the examination region received from the examination region input device 3 from the selection criterion parameter file 4b, and compares the age received from the patient information input device 2 with the age standard. If the former is larger than the latter, an adult scan protocol is selected, and if the former is smaller than the latter, a pediatric scan protocol is selected. Further, the scan protocol selection device 5 includes a confirmation button BC for confirming the completion of the selection of the scan protocol, and a child selection button BI for selecting the child scan protocol. Confirmation button B without the operator pressing the child selection button BI
When C is pressed, of the scan protocols selected according to the age, the one corresponding to the examination site is taken out of the scan protocol file 4a, and the CT scanner T
Send to On the other hand, when the operator presses the child select button BI and then presses the confirm button BC, the child's scan protocol corresponding to the examination site is extracted from the scan protocol file 4a and transmitted to the CT scanner T. This is because, in consideration of the physique and the like of the patient, there is a case where it is desired to adopt the pediatric scan protocol even if the patient is old. The CT scanner T stores the transmitted data in the database DB.

Next, the operation of the scan protocol setting device 1 will be described with reference to the flowchart shown in FIG. In step S1, the operator inputs patient information using the patient information input device 52. In step S <b> 2, the operator inputs an examination part using the examination part input device 3.

In step S3, the scan protocol selection device 5 extracts the age threshold value corresponding to the examination region from the selection reference file 4b and compares it with the age of the patient. Then, if the patient's age is smaller than the age threshold, step S
The process proceeds to step S4, and if the age of the patient is larger than the age threshold, the process proceeds to step S5. In step S4, the scan protocol selection device 5 selects a pediatric scan protocol.
In step S5, the scan protocol selection device 5
Select an adult scan protocol.

In step S6, the scan protocol selection device 5 determines whether or not the child selection button BI has been pressed. If the child selection button BI has been pressed, the process proceeds to step S7. If the child selection button BI has not been pressed, the process proceeds to step S8. In step S7, the scan protocol selection device 5 selects a scan protocol for children.

In step S8, the scan protocol selection device 5 determines whether the confirmation button BC has been pressed. If the confirmation button BC has not been pressed, the process returns to step S6, and if the confirmation button BC has been pressed, the process returns to step S9.
