Medical ultrasound scanners have become one of the indispensable tools in modern medical diagnosis. It forms images inside the body through ultrasound technology, which can help doctors observe and diagnose various internal diseases. Medical ultrasound scanners are widely used in the field of internal medicine due to their non-invasive, radiation free, and strong repeatability, providing more accurate data for disease diagnosis.

1、 Principles of Ultrasonic Technology

Medical ultrasound scanners use the echoes of sound waves to form images. When ultrasound passes through human tissue, it is reflected by factors such as different densities and interfaces in the tissue. These echoes are received by probes in the scanner and transmitted to the computer, which then converts these signals into two-dimensional or three-dimensional images. By observing these images, doctors can determine the shape, size, structure, and abnormalities of tissues, thereby making disease diagnosis.

2、 Application of Ultrasound in Internal Medicine Diseases

1. Liver diseases: Medical ultrasound scanners can help check the size, shape, and structure of the liver, as well as the presence of abnormal conditions such as lumps, cysts, and stones. In addition, color Doppler technology can also observe the blood flow dynamics of the liver, helping to determine the nature of liver diseases.

2. Kidney disease: ultrasonic scanner can help detect Kidney stone disease, masses, cysts and other abnormalities by observing the shape and structure of the kidney. In addition, the renal blood flow dynamics can also be observed by ultrasound to determine whether the renal function is normal.

3. Cardiovascular disease: The ultrasonic scanner can help evaluate the structure and function of the heart, and determine whether there are heart valve diseases, myocardial infarction and other diseases. Color Doppler technology can also be used to observe the blood flow dynamics of the heart and judge whether the heart valve and ventricular function are normal.

4. Thyroid disease: The ultrasonic scanner can observe the size, shape, structure and blood flow of the thyroid, and help doctors judge the nature and condition of Thyroid neoplasm, nodule, inflammation and other diseases.

5. Digestive tract diseases: Ultrasound scanners can observe the morphology and structure of the gastrointestinal tract, helping to diagnose gastrointestinal tumors, ulcers, polyps, and other diseases. In addition, through transesophageal ultrasound examination, the condition of the esophagus and stomach structure can be observed, and diseases such as esophageal cancer can be diagnosed.

3、 The advantages of ultrasonic scanners

1. Non invasive: Ultrasound scanners do not require incisions and can directly observe internal organs through the skin, reducing patient pain and the risk of infection.

2. No radiation: Compared with imaging technologies such as X-ray and CT, ultrasound scanners do not generate radiation and are safer for the health of patients and healthcare workers.

3. Easy to operate: Ultrasonic scanners are easy to operate and can be flexibly used in different clinical environments. Doctors can quickly obtain images by placing the probe in the area to be examined.

4. Strong repeatability: Ultrasonic scanners can perform multiple examinations to observe changes in the condition and treatment effectiveness, providing a reference basis for adjusting treatment plans.

conclusion

Medical ultrasound scanners have become important tools in the diagnosis of internal medicine diseases due to their advantages of non-invasive, radiation free, easy operation, and strong repeatability. It can provide accurate data, help doctors observe and diagnose various internal medicine diseases, and provide a foundation for patients to develop personalized treatment plans. With the continuous progress of technology, it is believed that ultrasonic scanners will play a more important role in the future, safeguarding people's health.
