What is ultrasound?

Ultrasound is a procedure that uses high -frequency sound waves, called ultrasonic waves, to produce images of internal organs and the inside of the body. This form of display works to a large extent in the same way as Sonar. Ultrasonic images are often used in obstetrics, but have unusual uses including biopsy and echocardiographers. They can be used to create a static or movable image.

Sound waves passing through different objects are an integral part of the production of ultrasonic image. The ultrasonic sensor called the converter focuses on the scanning of the organ or body area and emits ultrasonic waves. The echo is produced when sound waves hit different tissues. The converter detects the echo and draws the data to the computer. The computer then turns the sound into images.

In order to move the converter easily over the skin, the gel is applied. This gel also helps to allow the converter as close as possible to the skin. It is possible to feel a slight pressurending area is fine due to inflammation. The converter can also be inserted do bodies for the test. Slight anesthesia is often used for internal tests.

After ultrasound, there are no limitation of activity. The image made of ultrasound is interpreted by a trained professional or radiologist who can provide the patient's results. The results are often transmitted to the patient's general practitioners.

Ultrasound has no side effects because it is not used. This is a relatively easy and cheap procedure. They also produce real -time images and can be used to help lead invasive procedures. The main problem with ultrasound is that it is not easy to distinguish between air and bone and is not good for imaging bones or lungs.

Ultrasound is commonly used to produce a sonogram or picture of the baby in the uterus. The image can be used for deupply the size of the child, reveal more children, identify some abnormalities and diseases, and is essential for amniocentesis. Among others belowThe mines that can be detected by ultrasound include early fetal death, imminent abortion and placenta positions. This procedure is used after a woman is pregnant for 16 weeks.

Further unusual use of ultrasound is used to explore internal organs. Tumors, swelling and cysts can be examined using these high -frequency waves. Echocardiographer is a special type of ultrasound used to explore the heart. It is a diagnostic procedure that focuses on structural abnormalities and blood flow, albeit valves.
