Latest Patents
St John's latest patents exemplify her expertise and ingenuity. The first patent, titled "Multi-frequency harmonic acoustography for target identification and border detection," introduces a vibro-acoustography imaging system that creates a detailed map of the mechanical response of a target exposed to acoustic radiation forces. Operating within a low kHz range using a confocal geometry, the system leverages two focused sinusoidal beams to establish a stress field at the beat frequency. This process correlates the emitted acoustic fields to the mechanical properties of target tissues, with a highly sensitive hydrophone detecting the acoustic emissions.
The second patent, "System and method for time-resolved fluorescence imaging and pulse shaping," describes a time-resolved fluorescence imaging system that brackets lifetimes without the need for precise lifetime extraction. Instead, it maps the distribution of fluorophores to yield simple and accurate fluorescence images. The accompanying illumination source circuit enhances the excitation pulse's shape, with one embodiment featuring an LED and stub line configured to generate a linear decay profile.
