Medical ultrasonic scanner is a non-invasive and reliable diagnostic tool in modern medicine. It makes use of the characteristics of the propagation, reflection, refraction and scattering of high-frequency ultrasound in human tissues to image and diagnose the internal structure of human body. Compared with other medical imaging devices, such as X-ray, CT, MRI, etc., ultrasonic scanners have the advantages of more safety, simplicity, non-invasive and low cost, so they are widely used in clinical medical diagnosis and treatment.
The medical ultrasonic scanner was first introduced into the field of clinical medicine in the 1950s. At that time, American doctors used ultrasonic detectors to check the change of fetal position and the position of umbilical cord, which marked the emergence of medical ultrasonic scanners in the field of obstetrics. With the progress of technology, medical ultrasonic scanners are gradually applied to many other medical fields, including cardiovascular, hepatobiliary, urinary, breast, ophthalmology and other fields.
Compared with other imaging technologies, medical ultrasonic scanner has the following advantages:
First of all, medical ultrasonic scanner is a non-invasive inspection method, which will not cause radiation damage and chemical damage to patients, and does not require injection of contrast agent. Therefore, no matter children, pregnant women or the elderly, they can receive ultrasound examination.
Secondly, in terms of operation, the medical ultrasonic scanner is very simple and easy to operate without completely removing the patient's clothes. There is no obvious pain during the examination, so the requirements for patient comfort are very low.
Furthermore, ultrasonic imaging can provide high-quality images and can be observed in real time. Because ultrasound can penetrate soft tissue, it can clearly display the internal structure of organs and tissues, and also observe the movement and blood flow of organs, which is helpful for doctors to diagnose and make correct treatment plans.
Finally, the cost of medical ultrasonic scanner is relatively low and it is widely used. Patients can receive examination and training in hospitals and clinics at all levels, which improves the accessibility and sustainability of medical services.
Medical ultrasonic scanners are also widely used in different medical fields. For example, in the field of obstetrics, ultrasound imaging can observe the growth and development of the fetus, evaluate the health status of the fetus, and warn of potential fetal abnormalities. In the cardiovascular field, ultrasonic imaging can observe the systolic and diastolic processes of the heart in real time, detect whether the heart function is normal, and also detect parameters such as blood vessel blockage and blood flow velocity
