The design of the UltraVision accommodates virtually every concept possible in Ultrasound from emulating one channel to implementing ten thousand channels by attaching modules. The design also allows the researcher access to every stage of the signal processing chain. There is an Application Programming Interface available to the user, or the UltraVision company can also supply programs to implement specific code for the researchers needs.
The UltraVision Research platform is designed to the extreme to obtain the maximum signal integrity, and so creates images clear of noise. The SAMTEC SEAF connectors which are designed for very low crosstalk and noise immunity from DC to 18 GHz are supplied so the input capacitance is minimized to <15 pf. UltraVision can also supply transducer kits for interfacing the researcher's 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 beam-formation is also processed with focusing and steering coefficients 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 transducer element's waveform with 4.15 nanosecond granularity of positive, negative, ground or high impedance. Lead Zirconium Titanate (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 form of pulse width modulation is an effective method of modulating the power or waveform in each element. This method facilitates 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 beam-formed 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 element's RF digitizations to the final acoustic line sample data that is supplied to the PC for image construction (scan conversion 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, in MATLAB and can have he UltraVision Company convert such algorithms into code that can be instantiated in the FPGA as a step in product commercialization.
