Measured in-vivo data for convex array
The RF data was obtained from measuring on the liver in a subcostal view of the vena porta
for a healthy male volunteer
using the SARUS experimental scanner
and a convex array probe. The resulting image for the first frame is shown
below.
Subcostal view of the vena porta
for a healthy male volunteer
Ultrasound scanner: | SARUS |
Scan mode: | B-mode (Duplex mode) |
Transducer: | BK 8820e, 3.5 MHz convex array probe |
Number of elements | 192 |
Transducer center frequency | 3.50 MHz |
Number of active elements in transmit | 64 |
Height of one element | 13 mm |
Width of one element | 0.30 mm |
Kerf (gap) between elements | 0.03 mm |
Convex radius | 60.3 mm |
Electronic focus depth | 42.2 mm |
Elevation focus | 65 mm |
B-mode frame rate: | 0.78 f/s |
Speed of sound: | 1540 m/s |
Pulse repetition frequency: | 100 Hz |
Sampling frequency: | 17.5 MHz |
Sample format: | uin16 |
The data is stored in the zip files (1 Gbytes):
https://courses.healthtech.dtu.dk/22485/files/ult_data/in-vivo/convex_array/convex_array_files.zip
It is taken from a B-mode sequence.
The B-mode data are in the directory: B_mode/seq_0001, where seq_0001 holds all
the data for the first image. Ten images are found in the directory.
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 matrix samples with the received signals for all 192 transducer elements.
The directory files/ult_data/in_vivo/convex_array/ also hold the files parameters.mat,
which contains structures with all the variables used for the measurement.
