The present invention relates to an X-ray field controlling device having a dose-area product meter embedded therein, the device comprising: a main body a light transmission collimating unit arranged in an interior of the main body an upper X-ray irradiation area adjusting unit arranged in the interior of the main body to adjust the irradiation area of X-rays irradiated from an X-ray tube device a lower X-ray irradiation area adjusting unit for adjusting, in connection with the upper X-ray irradiation area adjusting unit, the irradiation area of X-rays transmitted through the upper X-ray irradiation area adjusting unit and incident to the irradiation area and a dose-area measuring unit placed on an X-ray irradiation line between the upper X-ray irradiation area adjusting unit and the lower X-ray irradiation area adjusting unit so as to measure the X-ray dose transmitted through the upper X-ray irradiation area adjusting unit and incident to the irradiation area and reflect the light irradiated from the light transmission collimating unit toward the irradiation area of X-rays. A dose-area product meter sensor is miniaturized and installed within the X-ray field controlling device, thus reducing the overall volume and weight of the X-ray field controlling device. Thus, the location of the X-ray field controlling device can be easily controlled when performing X-ray imaging on an examinee, and the size of the dose-area product meter sensor can be reduced while maintaining the performance thereof, thus reducing unit production cost.La présente invention concerne un dispositif de commande de champ radiographique ayant un dispositif de mesure de produit de zone de dose intégré dans celui-ci, le dispositif comprenant : un corps principal une unité de collimation démission de lumière agencée dans un intérieur du corps principal une unité de réglage de zone dexposition aux rayons X supérieure agencée dans lintérieur du corps principal pour régler la zone dexposition aux ra
