Full Matrix Capture (FMC)

According to standards, FMC designs an acquisition scheme for which any aperture can be used in emission and reception with or without delay law. But traditionally, is an acquisition scheme for which each element of the array transmits in turn, and all elements record the response. For an array of N elements, this produces an N × N matrix of A-scans containing the raw transmit–receive data. FMC is not an image itself — it’s a data set that allows advanced reconstructions.
