PURPOSE:To adopt a control system by a computer, to confirm the operation of an aperture wing and to confirm the shape of irradiation objective, by adding a physically small size substance to an original irradiation device. CONSTITUTION:A rotational stand having radiant ray device and a radiant ray irradiation angle generator 31 are interlocked, and a radiant ray irradiation angle signal is generated and applied to a controller 34 and an aperture machine 32. Further, an aperture position detector 33 detects the aperture position of the machine 32 and applies the signal to a controller 34. The controller 34 makes operation for the signals from the devices 31 and 33 and discriminates the count operation of a picture element counter group 37, the control of the initial operation and the final count value. A signal is applied to a picture display device 38 or a picture recorder 39, and a calculator 35 operates a linear equation and a count condition equation of the counter group 37 using the equation. A storage device 36 stores the picture data, confirms the operation of aperture blades and the shape of irradiated objective. |
