Ultrasonic scanning is a common medical imaging technology. It uses the propagation and reflection characteristics of high-frequency sound waves in human tissues to generate images. It is widely used in the following aspects:

Gynecological diagnosis: Ultrasound can detect gynecological diseases, such as pregnancy, ovarian tumors, etc.

Examination of liver, pancreas and gallbladder: ultrasound can check whether there are lumps or other abnormalities in these organs.

Cardiac examination: ultrasound can evaluate the structure, function and blood flow of the heart.

Nervous system diagnosis: Ultrasound can help diagnose nervous system diseases, such as stroke and multiple sclerosis.

Bone system diagnosis: ultrasound can detect problems in muscles, joints and bones, such as fractures, synovial cysts, etc.

Ultrasonic scanning has the following advantages:

Safety: ultrasound has no radiation and no harm to human body.

Convenient: Ultrasonic examination can be carried out in the doctor's office or clinic, usually without hospitalization.

Clear: ultrasound can provide doctors with clear images to help determine the type and degree of disease.

Economy: Compared with other imaging technologies, ultrasound is cheaper and easier to obtain.
