How do you know it. ’. s SAFE?. EFSUMB Safety Committee. Why are we concerned about safety?. The range of clinical applications is becoming wider . The number of patients undergoing ultrasound examinations is increasing . Antti Meriläinen, Edward . Hæggström. Using high frequency acoustic waves for mm-/µm-scale imaging. Method is non-destructive. It “Sees” inside the sample. Ultrasound images differences of acoustic impedances. Krystal . Kerney. Kyle Fontaine. Ryan O’Flaherty. Basics of Ultrasound. Ultrasound is sound with frequencies higher than about 20 kHz. For medical ultrasound, systems operate at much higher frequencies, typically 1 – 10 MHz. Jessica Leis. KNH 404 .

To compare the frequency of use of ultrasound technology in the pregnant patient at KU Med and Auckland City Hospital. To identify the views of New Zealand OBGYN’s and OB patients about the use of routine ultrasound evaluations in the pregnant patient and evaluate patient concerns about ultrasonography. Sound waves are longitudinal!. Sound can be explained by understanding:. Speed. Intensity. . and loudness. Frequency and pitch. Most people hear sound between the frequency of 20Hz and 20,000Hz. . Anatomy of Sound. sound.  pulses are produced by a transmitter and directed into the body. As in sonar, reflections occur. They occur each time a pulse encounters a boundary between two tissues that have different densities or a boundary between a tissue and the adjacent .
