CARLSBAD, Calif., Aug. 13, 2012 — The emerging photoacoustic tomographic (PAT) imaging modality for minimally invasive cancer detection and diagnosis is getting closer to clinical realization with LEEOAT Co.’s laser micromachined miniature photoacoustic tomographic imaging sensor (PATIS) probes.
PATIS probes are based on the innovation of micromachined two-dimensional-ultrasound phase array transducer sensors, combined with fiber optic illuminators. The waterproof probes, with up to 1024 transducer elements, are custom tailored to accommodate specific PAT imaging requirements, namely sensing of weak photoacoustic signals above the noisy environment at broadband frequency of 5 to 50 MHz, while achieving symmetric computerized uniform architecture for beam-forming optimization.
The company has demonstrated 98% yield in the fabrication of PATIS probes, with elements’ interdistances of 50 to 750 µm, which are individually Z-interconnected with separate coaxial cables for high-speed tomographic imaging.
