Ultrasounds 101: What Every Patient Needs To Know

Types Of Ultrasounds

Ultrasound machines are divided into types of ultrasounds based on the type of transducer used. Transducers are the wands that transmit the sound waves into a person's body, and ultrasound technicians may use different types depending on the use of the ultrasound. A standard transducer has a short, slightly flat shape, and is passed over the skin to create an ultrasound image. For more complicated procedures, other types may be used. The transvaginal ultrasound is one of the most common types of ultrasound. It is an elongated wand that can be inserted into the vagina to get a closer look at the uterus and ovaries. A transrectal wand is similar, but it is shaped to fit into the rectum and is very helpful for diagnosing prostate problems. In cases where the doctor needs a better look at the inside of a patient's torso, they may use a transesophageal ultrasound, which is inserted into the esophagus and allows the ultrasound equipment to get a closer look at the heart and other organs.
