X-RAY CT DEVICE

摘要

[PROBLEMS] To provide an X-ray CT device capable of easily comparing an image quality estimated to be obtained when not using a scan dose optimization function and an image quality estimated to be obtained when using the scan dose optimization function at the stage of scan planning. [MEANS FOR SOLVING PROBLEMS] A 3D model of an examinee (17) is generated from scanogram projection data (S170).An image noise dispersion value corresponding to an imaging portion of the examinee is predicted from the 3D model. The predicted image noise dispersion value is compared to a desired value of the image index value inputted by a user so as to calculate a modulation pattern of the irradiation X-ray amount (S200). By predicting the image quality estimated to be obtained when using and not using the scan dose optimization function, each of the predicted results is displayed so as to be compared on a display device (5) (S230).
