Total Focusing Method (TFM)

TFM is a signal processing algorithm using data acquired in FMC mode. A computation zone is specified for the data reconstruction. This zone is meshed, and for each point on this grid, the focal-laws are calculated for the entire set of elements of the phased-array probe. All recorded signals are time-shifted accordingly before summation at every point of the grid. The loop ends when the reconstruction is done for every point of the mesh.

Data

The TFM algorithm uses all signals recorded using the FMC data acquisition mode , available on M2M systems.
