Depending on the procedure, your doctor could tell you to fast for a number of hours because food in the stomach may interfere with sound waves, and you must notify your doctor of all medications that you are taking at the moment.
1. The patient will change into a hospital gown so the ultrasound technician has an easier job because clothes restrict access as they are designed to cover the body, the gown might have a cut out for which ever part of the body is being looked at for the day
2. After the patient has changed and is prepared for the ultrasound by following their doctors orders, the sonographer will inform the patient to lay down on an examining table to begin the procedure
3. A jelly like lubricant will be applied to the area where the transducer will be placed because the sonograher does not want friction and it will help transmit the sound waves through the body
4. High frequency sound waves will be produced through the transducer into the area of interest and as the waves travel through your body they will pass through softer tissues as they are designed to, but when they hit a dense object, they will create an echo that will come back to the transducer and be processed and create the image
5. Once the technician is finished, they will clean up the area and the patient will have the freedom to do whatever they please with no restrictions
Science
An ultrasound can send about one to five megahertz through the body and this technology is closely related to radar and sonar. A frequency or wave of sound is sent out and passes through soft tissues in the body in this case and keeps going until it hits a dense object that bounces the sound wave back to the object that initially sent out the wave; the transducer. The machine calculates each time an echo is sent out and retrieved and this provides the distance between the transducer and the specified tissue/organ and then a 2-D image is created that shows what was in between the transducer and the boundaries which would be a denser object in the body.
