Abstract
An image pickup device comprises a matrix of rows and columns of image pickup elements. Image information is transferred in the column direction in the time-delay-and-integration mode. Two shift registers are associated with each column of image pickup elements. During a first period information from the image pickup elements of each column is transferred to a first one of each two shift registers associated with each column and during a second period information is transferred to the second one of each two shift registers associated with each column. Such an image pickup device can be used in radiography as a means for detecting x-ray radiation transmitted by a body under examination. In order to obtain a dual energy image a first or a second spectral center point is periodically imparted to the x-ray radiation synchronously with the first and second periods.
