Ultrasound Research

 

 

            The single FPGA design allows the researcher access to every stage of the signal processing chain. WinProbe can in circumstances  also supply programs to implement specific code for the researchers needs.

 

      The WinProbe Research platform is designed to extreems to obtain the maximum signal integrity and so creates images clear of noise so industry typical but niosy and high cross-talk zero insertion force transducer connectors are not used. Instead  the SAMTEC SEAF connectors which are designed for crosstalk and noise immunity from DC to 18 GHz are supplied.  The input capacitance is also minimized to <15 pF.  WinProbe can also supply kits for  interfacing researchers transducers to the system.

 

       The analog to digital converters are 14-bits and supply 75dBFS clarity and operate at 40 or 60 MHz.  All the  beamformation is also processed with focusing and steering coefficient updated at the clock speed of 40 or 60 MHz.

 

      Complete control over the transmit functionality is available to the researcher in that he or she may design each elements waveform with 4-nanosecond granularity of positive, negative, ground or high impedance.  Lead Zirconium Titinate (PZT) elements and even well designed single crystal elements with multiple matching layers and damping backing layers have a relatively narrow bandwidth of 70-120% which limit their sensitivity to ranges in the 1- 30 MHz useful transducers and are thus insensitive to the changes at 250 MHz where the pulsers operate so this pulse width modulation is an effective method of modulating the power or wavform in each element. This method faclitates spatial apodization windows to be placed over the apertures of multiple elements for visibly better imaging than using a square spatially apodized window.  Codes like Golay Codes can be implemented by the researcher who may then take the RF element or beamformed data to apply through a description process of his or her own design.

 

      Complete access of the data path is available to the researcher from the individual elements RF digitization's to the final acoustic line sample data that is supplied  to the PC for image construction (scanconversion plus processing) in the PC's graphical processing unit's hundreds of cores.  Generally the algorithms of ultrasound processing are processed faster (in real  time) in the FPGA but the researcher may create his or her own algorithms in, for example, MATLAB and can have WinProbe convert such algorithms into code that can be instantiated in the FPGA as a step in product commercialization.
