Latest Patents

One of his latest patents is titled "Dynamic receive aperture transducer for 1.5D imaging." This innovative ultrasound imaging system allows for the generation of 1.5D image information from a single firing of a linear transducer array. It achieves this by enabling dynamic control over the receive aperture. The system includes a transducer with a linear array of piezoelectric elements arranged in distinct rows. The transducer can provide acoustic pulses from elements of one row in response to driving signals and receive return signals from additional rows. A receiver is coupled to the transducer to receive a summed signal corresponding to these return signals. The receiver features low voltage switches and a high voltage switch that work together to vary the focusing characteristics of the imaging system. A processor generates a 1.5D image using the summed signal.

Another significant patent by Miller is "Digital processing for steerable CW Doppler." This Doppler medical ultrasound apparatus includes means for transmitting ultrasound energy into a body and a plurality of parallel channels for receiving echoes. It digitizes the echoes and forms a received beam signal. The system processes these beam signals to produce a Doppler signal that represents movement in a target volume within the body. Additionally, it features a summing circuit for adding a common dither signal to each received echo, enhancing the accuracy of the digitization process.
