Outline of Presentation

• What is an Ultrasound?• How Ultrasounds Work• 2D, 3D, and 4D Imaging• Equipment Used• Advantages of 4D• Conclusion• References

What is an Ultrasound?

•Medical imaging technology•High frequency sound waves and echoes

How Ultrasounds Work

•Probe transmits sound pulses•Sound waves hit boundary•Waves reflect back •Waves relayed to machine•Distance of waves calculated•Image displayed from distances

The Ultrasound Machine

•Transducer Probe•CPU•Transducer Probe Controls•Display•Keyboard•Disk Storage Device•Printer

Pictures of 2D and 3D Ultrasounds

4D Video

GE Voluson 4D Ultrasound Machine

•Takes 3D images and adds time•25 volume scans per second in three-dimensional planes.•11 probe types

Advantages of 4D Ultrasounds

•Determine fetal age •Analyze fetal development •Evaluate multiple pregnancies •Evaluate high-risk pregnancies

More Advantages

Detect:•Abnormal bleeding•Ovarian tumor/fibroids •Ectopic pregnancy•Abnormalities•Structural problems

Conclusion

Ultrasounds are:• A type of computer• Used to look at the fetus• Now using four-dimensional photos• Used to detect abnormalities• Very helpful to the medical industry
