Abstract
A digital detector includes a conversion block intended to convert incident radiation into electric charge; an electronic card that converts the electric charge into a digital image, the conversion block comprising N conversion stages superposed on one another, N being an integer between 2 and M, each of the N conversion stages comprising: a monolithic substrate; a first converter assembly in the form of a polygonal matrix array, M being the number of sides of the polygonal matrix array, M preferably being equal to 4, and configured so as to generate the electric charge on the basis of the incident radiation; an addressing and driving module for addressing and driving the matrix array, the addressing and driving module being arranged on the monolithic substrate along one side of the polygonal matrix array; each of the N conversion stages being oriented by at least 1/M of a turn with respect to the other N−1 conversion stages of the conversion block, and with an orientation distinct from the other N−1 conversion stages of the conversion block.
