Ultrasonic scanner is a commonly used medical diagnostic device, which obtains image information by sending ultrasound to human tissues, and can be used to detect internal organs, tissues, and blood vessels in the human body. In addition to being widely used in the medical field, ultrasonic scanners are also used in fields such as industrial control, material testing, and biological research. This article will deeply explore the application and technology of ultrasonic scanners.
1、 Principle of ultrasonic scanner
The principle of ultrasonic scanners is based on acoustic imaging technology. It utilizes the speed difference and reflection characteristics of ultrasonic waves propagating in different media to obtain images of the internal structure of the human body. When ultrasound is emitted from a transmitter and passes through human tissue, it encounters tissues or organs with different densities and generates reflections in these areas. These reflected signals are captured by the receiver and converted into two-dimensional or three-dimensional images based on their intensity and time delay, displaying the morphology and structure of the internal organs and tissues of the human body.
2、 Application of ultrasonic scanner in medical field
Ordinary B-ultrasound examination
Ultrasound scanners can be used in many medical applications, including ordinary B-ultrasound examinations. This examination is a noninvasive diagnostic method that can help doctors detect abnormalities in internal organs such as the liver, pancreas, spleen, lymph nodes, and thyroid gland. In addition, it can also detect gynecological problems such as endometriosis and uterine fibroids.
Vascular ultrasound examination
Ultrasound scanners can also be used for ultrasound examination of blood vessels. This test can help doctors detect heart disease, arteriosclerosis, and other cardiovascular problems. This technique can be used to perform vascular examinations in the neck, upper limbs, lower limbs, and iliac arteries to detect conditions such as thrombosis and stenosis.
Cardiac ultrasound
Ultrasound scanners can also be used for cardiac ultrasound examination. This diagnostic method can help doctors assess heart size and function, and detect problems such as abnormal flow and valve movement. Cardiac ultrasound can also be used to detect congenital heart disease and other heart problems.
3、 The Technology of Ultrasonic Scanner
The technology of ultrasonic scanners is continuously developing, including the following aspects:
3D and 4D imaging technology
Traditional B-ultrasound imaging is a two-dimensional image that can only display the shape and shape of the internal structure of the human body, but cannot provide depth information. Today's ultrasound scanners are widely upgraded to include 3D and 4D imaging technology, which can provide realistic three-dimensional images and observe depth information of tissues and organs. 4D imaging technology can also capture images of movement, such as fetal activity in the mother's womb.
