Medical ultrasound scanner is a non-invasive diagnostic tool widely used in modern medicine, which uses high-frequency sound waves to non-invasive detect the internal structure of the human body. Since the 1980s, with the continuous development and improvement of ultrasound technology, medical ultrasound scanners have become an important part of medical imaging diagnosis, especially playing an irreplaceable role in fields such as prenatal examination of pregnant women, cardiovascular disease, and tumor detection.

2、 The working principle of medical ultrasonic scanner

Medical ultrasound scanners scan human tissues through the emission and reception of high-frequency sound waves. Firstly, a high-frequency sound wave (usually in the range of 2MHz to 10MHz) is emitted, which is reflected when encountering human tissue and then captured by the receiver and converted into an image. Through computer processing, these reflected signals are transformed into visible images, allowing doctors to intuitively observe the structure and morphology of the human body.

3、 The Application of Medical Ultrasonic Scanner

Prenatal examination of pregnant women: Medical ultrasound scanners are important tools for prenatal examination of pregnant women, which can confirm the health status of the fetus by conducting detailed observations of the fetus's head, heart, spine, limbs, etc.

Cardiovascular disease: Medical ultrasound scanners can clearly display the structure and function of the heart, playing an important role in the diagnosis of cardiovascular diseases such as cardiomyopathy, valvular heart disease, congenital heart disease, etc.

Tumor detection: Medical ultrasound scanners can detect tumors in the human body, such as liver tumors, breast tumors, thyroid tumors, etc., providing information on the location, size, morphology, and other information of tumors, providing a basis for doctors to formulate treatment plans.

Other applications: Medical ultrasound scanners are also widely used in fields such as brain diseases, musculoskeletal system diseases, digestive system diseases, etc., providing important support for doctors' diagnosis.

4、 Progress and Development of Medical Ultrasonic Scanners

Color blood flow imaging: Medical ultrasound scanners can display the blood flow inside blood vessels through color blood flow imaging technology, helping doctors better understand the blood flow status of diseased tissues and organs, and providing more information for diagnosis.

3D and 4D imaging: Medical ultrasound scanners have evolved from basic 2D imaging to 3D and 4D imaging, which can provide more three-dimensional images and help doctors accurately judge the condition.

High frequency and ultra-high frequency technology: With the advancement of technology, the frequency of medical ultrasound scanners has increased from basic 2MHz to 10MHz to ultra-high frequency, such as 50MHz or even higher, which makes the image resolution higher and can better display small lesions.

Artificial intelligence assisted diagnosis: The application of artificial intelligence technology has further improved the diagnostic accuracy of medical ultrasound scanners. Through technologies such as deep learning and pattern recognition, medical ultrasound scanners can automatically identify lesion areas and even provide preliminary diagnostic opinions, greatly improving diagnostic efficiency.

5、 Conclusion

In summary, medical ultrasound scanners, as an essential tool for non-invasive diagnosis, have a wide range of applications and continuously advancing technology. With the further development of technology in the future, we believe that medical ultrasound scanners will play a greater role in the field of medical imaging diagnosis and make greater contributions to human health. At the same time, we also look forward to the application of ultrasound technology in more fields, bringing benefits to more people.
