Full Matrix Capture

Full matrix capture (FMC) is a specific data-acquisition process using ultrasonic phased-array probes.

For an array of N elements, each element is successively used as transmitter, while all other elements are used receivers.

The data are organized in a matrix S that contains all the acquired signals. Sij contains the signal transmitted by element i and received by element j.

The full signal-matrix may now be used for processing. Total Focusing Methods (TFM) may be computed from this data set.

ith element is firing, jth element is listening. Sij is recorded in the signal matrix. For an array with N elements, i and j belong to [1; N].
