The invention involves a radiological image detection system capable of cooperating with a scanning X-ray generator ( 10 ) designed to produce X-ray radiation ( 1 ) scanning a surface ( 2 ) to be imaged. The scanning X-ray radiation ( 1 ) irradiates, portion ( 2 ') after portion, the surface ( 2 ) to be imaged. The X-ray radiation from a portion ( 2 ') carries a radiological image of said portion. The detection system comprises an image sensor ( 22, 52 ) which is stationary with respect to the scanning and which is dimensioned so as to be able to acquire an image of the entire surface ( 2 ) to be imaged by the X-ray radiation from the portions ( 2 '). In addition, it comprises means ( 24, 240 ) for limiting, at a given time, the acquisition of the image sensor ( 22, 52 ) to that of the image of the portion ( 2 ') irradiated at that time, these limitation means being in synchronism with the scanning and in geometrical correspondence with the irradiated portion ( 2 ').
