    • Ultrasound
    • What is Ultrasound?  Device that uses high frequency sound waves  Used to view tissues and organs  Commonly used on pregnant women to view and identify problems with the baby
    • Advantages of Ultrasound  Can be used to treat heart problems  Is quick and painless  Can identify lesions  Can detect blood flow  Gives pregnant women information about their child's growth  Does not use radiation  No known harms to people
    • Disadvantages of Ultrasound  Is not available everywhere  Not all insurance companies cover it  Can’t detect many cancers  May not know if a mass is a malignant or not  It is expensive  Not 100 percent accurate
    • Parts of the Ultrasound Machine  Transducer probe  CPU – computer that does the calculations and tells     transducer to work Transducer pulse control – controls settings for the probe Display – Displays image Disk storage device (CD) – stores image Printer
    • Transducer Probe  Main part of the machine  Must be in contact with skin  Makes and receives sound waves and echoes  Uses quartz crystal in the probe  Quartz is a piezo electric crystal which will vibrate and create sound waves when receiving electrical current  Quartz crystal also used to listen for ultrasound waves when waves return
    • Science behind Ultrasound and Process  Is a medical imaging technique that uses high frequency sound waves and their echoes  1 – 5 megahertz sound pulses into your body  Sound waves hit boundary or air between tissues then bounce back to probe  CPU calculates distance from probe to boundary using speed of sound in tissue and echoes return to display and image
    • Ultrasound Examination Method Ultrasoundgrapher:  Applies jelly like substance applied to skin to improve transmission of sound waves  Uses jelly to eliminate air bubbles  Covers probe with plastic cover  Moves probe over skin to get images
    • Benefits to Society  Detects disease before it progresses  Doctors can pinpoint trouble spots and help people avoid life-threatening heart conditions  Doctors can predict the developing of artery disease and offer early treatment
    • Political and Health Issues and Solutions Issues • Solutions • maternal-fetal medicine specialist performing ultrasound not able to give patient proper feedback • Pre-natal diagnostic technique act has made it illegal to sell ultrasounds to unqualified people • getting a picture of the fetus for entertainment reasons or determining the gender of the child Sellers must also provide details of ultrasound buyers to the government and every ultrasound machine must be registered • Sonographers contact ergonomists (people who study efficiency in work related environments) to investigate the environment as well as work practices
    • Social Issues and Solutions Issues • parents are now killing babies even before they are born due to their dislike of their gender • advancements in technology is also causing imbalance in gender between developed and developing countries due to cultural ideals Solutions • government creating laws to eliminate gender biases for long term • Will result in improvement of quality of life of women and their child in developing countries
