   Hi, anyone noticed that there is a little difference with the output sensordata from the Matlab function kspaceFirstOrder3D and its C++ version kspaceFirstOrder3DC?

   It can be tested with example_us_bmode_linear_transducer.m. It can be found there is a time shift between the Matlab and C++ waveform, and the transmitting waveform ( the header of the receiving waveform) are not the same. Maybe due to the function of the transducer.combine_sensor_data?

   For the finial B-mode image, the background level of C++ is a little higher than that of Matlab's.

   Hi biaojiang,

   Are you using a transmit apodization? See here.

   HI, Bradley,

   Thanks. Yes, I used Hanning transmit apodization, so the results are not correct, and I should set "Rectangular"? Why there were no warnings when I set "Hanning".
