  1. 50 MHz “Aviso” Linear probe in anterior segment ultrasound Dr P.A.Good Birmingham U.K.

  2. Frequency and depth

  3. THE NEW & UNIQUE PROBE50 MHz LIN • 50 MHz : QM transducer • Linear : better perpendicularity • Wide scan : to visualize the whole AC

  4. SECTOR FOR RETINA SECTOR FOR AC SECTOR PROBES

  5. ARC LINEAR NEW PROBE TECHNOLOGY

  6. Short focal length probe (20 MHz) • Whole of anterior segment can be seen. • No need for waterbath. • Adjustment of probe position maintains different focal plane over 10 mm. • Displaced IOL implant • Note in the right eye the lens is too anterior, resulting in iris bowing and refractive error

  7. UBM ULTRASOUND BIOMICROSCOPY C.J. PAVLIN (50 MHz)

  8. High Frequency Ultrasound Imaging • Anterior Segment Imaging : 50MHz =>1991:UBM :Sector scan => Glaucoma C Pavlin => 1994 : ARTEMIS: Arc Scan => Refract. Surg D Reinstein, R Silverman, J Coleman => 2005 : AVISO: Linear Scan Quantel Medical • Posterior Segment Imaging : 50 MHz =>1999:US Patent PCT FR 98/02788 (Michel Puech ) => 1999: IOVS : 5O MHZ Ultrasound Imaging of Macula Michel Puech
