Transcript of Science Project: Ultrasound

Ultrasound ? Background How Video display screen
Warm water-based gel Safety Measures Side qualify? Transducer; sends sound waves and records echoing waves
Warm water-based gel; eliminates air pockets between transducer and skin
When a sound wave strikes an object, it bounces back or echoes
By measuring echo waves, it is possible to determine the distance, size, shape, and consistency of the object
Transducer is pressed firmly against the skin; Sonographer sweeps it over the area of interest Hospitals
Health Care Clinics Average of 8 weeks
Accredited Training Program
Canadian Association of Registered Diagnostic Ultrasound Professionals; must meet their clinical and academic requirements 100% success rate Usually not harmful
Physical pain; a burning feeling
Disorientation Ian Donald invented first ultrasound Commonly called "Sonography"
Inspired by Sonar's (boat and submarine)
Uses high frequency sound waves to produce images of tissues and internal body organs View tissues, internal organs, blood flow, and fetuses inside womb
Show structure and movement of internal organs and blood flow also used to guide needles when peforming needle biopsy of tissue
used to study fetus during pregnancy
used during amiocentis test
used to check heart problems; echocardiogram minimal preparation
no food or drink for 6-8 hours before ultrasound examination
mothers should drink 4-6 glasses of water 1-2 hours before examination
no safety measures need to be taken other than necessary preparations if person has pain, swelling or infection
to examine internal organs
diagnose heart condition
guide biopsy of breast cancer
to detect blood clots, tumors etc. private ultrasound clinics charge $100 - $300
OHIP covers ultrasound costs for pregnancy
echoslerotherapy is covered if vein is larger than 5mm or if there is pain
otherwise costs $450
CT and MRI and best alternatives
