What do you mean by non-invasive examination?

Non-invasive examination is a non-invasive examination method, which is common in hospitals, clinics and scientific research institutions. Non-invasive examination can use optical, acoustic, electromagnetic and other technical means, such as X-ray, ultrasonic, magnetic vibration and so on. This method will not cause physical harm and pain to candidates, and the examination time is short and the results are accurate. Therefore, noninvasive examination has become an indispensable tool in the field of modern medicine.

Compared with traditional invasive examination methods, non-invasive examination has the advantages of simple operation, less pain in treatment and no trauma to human body. For example, in the examination of cardiovascular and cerebrovascular diseases, non-invasive techniques can examine the conditions of the heart and blood vessels through intravascular optical or ultrasonic imaging, which is safer and more comfortable than percutaneous coronary angiography. In addition, non-invasive examination is less affected by personal medical experience, which can improve the reliability of examination results.

In today's society, with the continuous progress of science and technology, nondestructive testing technology has also been widely used. Not only in the medical field, non-invasive examination is also widely used in scientific research, industrial production, environmental monitoring and many other fields. With the development of big data and artificial intelligence technology, the application prospect of nondestructive testing technology is broader. It can be predicted that in the future field of science and technology, nondestructive testing technology will make great achievements and have a far-reaching impact on human production and life.
