Ultrasound is sound that has a wave frequency higher than the human ear can detect. ... Sonar stands for sound navigation and ranging. It is used to locate underwater objects such as submarines. Ultrasonography is the use of reflected ultrasound waves to “see” inside the body.
Ultrasound imaging is based on the same principles involved in the sonar used by bats, ships and fishermen. When a sound wave strikes an object, it bounces back, or echoes. By measuring these echo waves, it is possible to determine how far away the object is as well as the object’s size, shape and consistency.
Is sonar an ultrasound?
A common use of ultrasound is in underwater range finding ; this use is also called Sonar. An ultrasonic pulse is generated in a particular direction.
What is the difference between sonography and ultrasound?
Sonography is a medical imaging technique that uses high-frequency sound waves to produce images of internal body structures. Sonography is also known as ultrasound. After the X- ray test , ultrasound is the most used diagnostic imaging technique. ... A transducer is a device used for sonography that emits ultrasound waves.
What are the disadvantages of ultrasound?
Disadvantages of ultrasonography include the fact this imaging modality is operator and patient dependent, it is unable to image the cystic duct , and it has a decreased sensitivity for common bile duct stones.
What animals can detect ultrasound?
Echolocation. Animals such as bats and dolphins send out ultrasound waves and use their echoes, or reflected waves, to identify the locations of objects they cannot see. This is called echolocation. Animals use echolocation to find prey and avoid running into objects in the dark.
What are 3 uses of ultrasound?
Doctors commonly use ultrasound to study a developing fetus (unborn baby) , a person’s abdominal and pelvic organs, muscles and tendons, or their heart and blood vessels. Other names for an ultrasound scan include sonogram or (when imaging the heart) an echocardiogram.
How much does an ultrasound cost?

Is a sonographer a doctor?
Sonographers are medical professionals trained to use ultrasound diagnostic imaging technology to capture detailed images of different areas of patients’ bodies. ... Like a doctor , you’ll need an excellent bedside manner to be an effective sonographer .
Who gets paid more radiologist or sonographer?
You might also be wondering about ultrasound vs radiology salary. Radiologists are doctors, which can earn a significantly higher salary, in the range of physicians and surgeons. ... radiology tech salary is a little bit closer, with sonographers (ultrasound techs) coming in a little higher nationally.
Is ultrasound harmful for body?
Although Ultrasound cannot be heard by humans, at high decibels it can still cause direct damage to human ears. Ultrasound in excess of 120 decibels may cause Hearing damage. Exposure to 155 decibels causes heat levels that are harmful to the body. 180 decibels may even cause death .
Does sonography hurt?
The test itself doesn’t have risks. Unlike X-rays, an ultrasound doesn’t use radiation. A transabdominal ultrasound shouldn’t hurt . You might feel some discomfort during a transvaginal or transrectal ultrasound when the transducer is inserted.
Is ultrasound better than CT scan?
CT scan is no more accurate than ultrasound to detect kidney stones, study finds. Summary: To diagnose painful kidney stones in hospital emergency rooms, CT scans are no better than less-often-used ultrasound exams, according to a clinical study conducted at 15 medical centers.
How much radiation do you get from an ultrasound?
Because ultrasound images are captured in real-time, they can also show movement of the body’s internal organs as well as blood flowing through the blood vessels. Unlike X-ray imaging, there is no ionizing radiation exposure associated with ultrasound imaging.
Can you tell if a tumor is cancerous from an ultrasound?
Ultrasound images are not as detailed as those from CT or MRI scans. Ultrasound cannot tell whether a tumor is cancer . Its use is also limited in some parts of the body because the sound waves can’t go through air (such as in the lungs) or through bone.
How do humans use ultrasound?
A small device called an ultrasound probe is used, which gives off high-frequency sound waves . You can’t hear these sound waves, but when they bounce off different parts of the body, they create “echoes” that are picked up by the probe and turned into a moving image.
