Adaptive filter for dual energy radiographic imaging

摘要: A radiographic scanner (A) generates a high energy image representation which is stored in matrix (V) and low memory (U). pair of filter functions selecting circuits (C) select first or soft tissue specific function second bone function, respectively. The circuit selects adjusts the accordance with pixel value for each corresponding values. Convolvers (44, 46) convolve values from representations selected adjusted functions. transform (48) transforms filtered into other material (42). adjusting are convolved by convolvers (54, 56). (58) basis image.
