Simulated data for convex arrayThe RF data was obtained from simulating wires in a phantom by using the Field II program and a convex array probe. The geometry of the phantom is shown below, where wires are placed with a spacing of 1 cm.
The data is stored in the zip archive (642 MBytes): It is taken from a duplex sequence with intermixed B-mode and duplex flow emissions. The B-mode data are in the directory: duplex/B_mode/seq_0001, where seq_0001 holds all the data for the first image. A file elem_data_em0XXX.mat exist for each emission, where XXX is from 1 to 129. For the first file elements 1 to 64 has been used for transmission and for the next element 2 to 65 and so forth. Element 1 has the most negative x coordinate value. The file holds the matix samples with the received signals for all 192 transducer elements. The zip file also hold the files parameters.mat and sim_parameters.mat, which hold structures with all the variables used for the simulation of the phantom.
