In today's medical field, advanced technology and equipment are constantly driving the improvement of diagnosis and treatment levels. Among them, medical ultrasound scanners, as a key technical means, have been widely used in the diagnosis and treatment of various diseases. This article will delve into the working principle of medical ultrasound scanners and their application value in the medical field, showcasing the perfect combination of technology and medicine.

1、 The working principle of medical ultrasonic scanner

Medical ultrasound scanners utilize the reflection and propagation characteristics of high-frequency sound waves to non-invasive image the internal structure of the human body. It generates a series of high-frequency sound waves that penetrate human tissues and reflect back to the probe when encountering different interfaces, forming an echo. These echoes are converted into electrical signals and further processed to form images.

Specifically, the workflow of medical ultrasound scanners is as follows:

Emission of sound waves: The probe emits high-frequency sound waves into the interior of the human body, and the sound waves will be reflected back when encountering different interfaces during their propagation.

Receiving Echo: The probe receives the reflected sound waves and converts them into electrical signals.

Data processing: After processing the electrical signal, it forms image data based on different amplitude and phase information.

Imaging display: Real time display of image data on the screen, forming a two-dimensional image of the internal structure of the human body.

2、 Types and characteristics of medical ultrasound scanners

Type: Medical ultrasound scanners can be divided into abdominal ultrasound, cardiac ultrasound, breast ultrasound, musculoskeletal ultrasound, etc. based on the location and purpose of use. Different types of ultrasound scanners have different probe designs and operating methods.

Features:

Non invasive: Medical ultrasound scanners are non-invasive to the human body, avoiding the pain and risks brought to patients by invasive examinations.

Real time: Medical ultrasound scanners can generate real-time images of the internal structure of the human body, making it easy for doctors to diagnose and monitor in real time.

High resolution: Medical ultrasound scanners can generate high-resolution images that clearly display the fine structures inside the human body.

High sensitivity: Medical ultrasound scanners have high sensitivity in diagnosing diseases and can detect early lesions.

3、 The Application Value of Medical Ultrasonic Scanners in Medicine

Diagnosis of abdominal diseases: Abdominal ultrasound can diagnose lesions in abdominal organs such as the liver, gallbladder, pancreas, spleen, etc., such as liver cancer, cholecystitis, pancreatitis, etc. Observing information such as organ shape, size, and echo can help doctors make accurate diagnoses.

Cardiovascular disease diagnosis: Cardiac ultrasound can evaluate the structure and function of the heart, diagnose cardiovascular diseases such as coronary heart disease, cardiomyopathy, and valvular heart disease. At the same time, it can also provide guidance and monitoring for cardiac surgery and interventional therapy.

Diagnosis of gynecological and obstetric diseases: Gynecological ultrasound can diagnose gynecological and obstetric diseases such as uterine fibroids, ovarian cysts, and fetal developmental abnormalities. By observing the morphology, size, and fetal development of the uterus and ovaries, accurate prenatal diagnosis is provided for pregnant women.

Diagnosis of neurological diseases: Brain ultrasound can diagnose neurological diseases such as cerebral hemorrhage, cerebral infarction, and encephalitis. By observing information such as cerebral vascular blood flow and brain parenchymal echo, it is helpful for doctors to determine the nature and degree of brain lesions.

Interventional therapy guidance: In interventional therapy, ultrasound guidance can accurately guide the catheter or instrument to the lesion site, improving the efficacy and safety of interventional therapy. For example, in treatments such as tumor ablation and abscess drainage, ultrasound guidance can accurately reach the target site and reduce damage to surrounding tissues.

Diagnosis of musculoskeletal diseases: Musculoskeletal ultrasound can diagnose musculoskeletal diseases such as muscle injuries, arthritis, and fractures. Observing the shape, structure, and blood flow of muscles and bone joints can help doctors determine the nature and degree of the lesion.

Tumor monitoring: Tumor patients need to undergo regular tumor monitoring during the treatment process. Ultrasound examination can evaluate the size, morphology, and relationship with surrounding tissues of tumors, monitor their growth and changes, and provide a basis for doctors to adjust treatment plans.

Health screening: Health screening is an important component of preventive medicine. Abdominal ultrasound examination can detect abnormal lesions in organs such as the liver, gallbladder, pancreas, and spleen, and timely detect and intervene in potential health problems.

Intraoperative navigation: During the surgical process, ultrasound technology is combined with a navigation system to display the position and depth of surgical instruments in real-time, improving the accuracy and safety of the surgery. For example, in neurosurgery, intraoperative navigation can accurately locate the lesion site and guide surgical procedures.

Rehabilitation assessment: In rehabilitation medicine, ultrasound examination can evaluate muscle strength, joint range of motion, and soft tissue damage, providing a basis for patients to develop personalized rehabilitation plans. At the same time, regular evaluations can be conducted during the rehabilitation process to monitor the patient's recovery and adjust the treatment plan in a timely manner.

4、 Conclusion and outlook

Medical ultrasound scanners have extensive application value in the medical field, providing strong support for the diagnosis and treatment of various diseases. Its non-invasive, real-time, high-resolution, and high sensitivity characteristics give it unique advantages in clinical practice. With the continuous progress of technology, the technology and performance of medical ultrasound scanners
