There is a plethora of ultrasound and medical terminology used during the ultrasound process. Here are the definitions for some of the key words and phrases.
Ultrasound scans: "Sound waves that are beamed into the body causing return echoes that are recorded to 'visualize' structures beneath the skin." (Medicine Net)
Transducers: "Convert one form of energy to another [during the process]." They are the cameras of the operation and can also be known as probes or the scanheads. (Tufts Ultrasound Terminology)
Gel couplant: "A trans-sonic material which eliminates the air interface between the transducer and the animal's skin." (Tufts Ultrasound Terminology)
Doppler ultrasound: "...a special form of ultrasonography that images and examines blood flow. In particular, a Doppler ultrasound examines the changes in pitch in the soundwaves produced, which provides information about blood flow." (Baby2See Ultrasonography)
Endoscopic ultrasound: "A procedure that combines endoscopy and ultrasound to obtain images and information about the digestive tract and the surrounding tissues and organs." (Med Terms)
Transvaginal ultrasound: "A technique in which sound waves are sent out by an ultrasound probe that has been inserted in the vagina. The waves go through the vaginal wall and bounce off the ovaries, and a computer uses the ultrasound echoes to create a picture [which is known as a sonogram]." (Med Terms)
