1. Ultrasounds New Technological Advances By Erin Sparks

2. Outline What is an Ultrasound? Ultrasounds as computers Improvements The Future Conclusion Sources

3. What is an Ultrasound? High-frequency sound pulses sent into body Sound waves reflect back when boundary is reached Machine calculates distance of waves A picture is formed

4. Ultrasounds as a Computer Has a CPU to: Send electrical currents to probe Do calculations to process data Form image on display

5. Ultrasounds as Computers Cont… Display is the monitor Keyboard allows operator to add notes and take measurements Thermal printers Storage on floppy disk, hard disk, CD, or DVD

6. Improvements to Ultrasounds 3D Ultrasounds combine many 2D pictures to form one 3D picture Can detect cancerous and benign tumors Detect abnormal child development

7. More Improvements GE 4D Ultrasound creates video of image by adding element of time Doppler Ultrasound allows the direction and speed of a moving object to be looked at Doppler is used to look at the heart

8. The Future of Ultrasounds Faster More memory Smaller More developed Popular

9. Conclusion Ultrasounds are: Used to look at the fetus Used to look into the body for problems Very similar to the setup of our computers Becoming more technologically advanced
