  1. Defining the Future in Ultrasound Technology GE Ultrasound Philip W. Ralls, Kevin P. Lee LA County + USC Medical Center Keck School of Medicine University of Southern California

  2. GE Ultrasound – 2001A History of Accomplishments • Digitally Encoded Ultrasound • Sophisticated Transmit / Receive Beamformers • Pulse Encoding • Coded Excitation – Penetration at Higher Frequency • Harmonic Imaging – Tissue and Contrast • B-Flow • Active Matrix Array Transducer Technology • Enhanced Spatial/Contrast Resolution • Others – EFOV, Virtual Convex Technology, 3D Sonography, High Resolution, US Contrast

  3. High Resolution

  4. Resolution - Epididymal Cyst, Ca++

  5. i12L - 200 Micron Imaging

  6. Pulse Encoded HarmonicsAdvantages Less Artifact Clearer, Better Images

  7. GB Sludge, Grating Lobes
