Measured data for convex array and matrix phantomThe RF data was obtained from measuring on wires in a phantom by using the SARUS experimental scanner and a convex array probe. The geometry of the phantom is shown below, where wires are placed with a spacing of 1 cm.
All the data is stored in the file (260 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, which hold structures with all the variables used for the measurement of the phantom. Resulting image for the matrix wire phantom |
