At present, doctors use different forms of ultrasound diagnostic methods, which can be divided into four categories: A-type, B-type, M-type, and D-type.

Type A: It is a method of displaying tissue characteristics using waveforms, mainly used to measure the diameter of organs to determine their size. It can be used to distinguish some physical characteristics of diseased tissue, such as the presence of substance, liquid or gas, etc.

Type B: Display the specific situation of the explored organization in the form of flat graphics. When conducting an examination, the first step is to transform the reflection signal of the human interface into different intensity light points, which can be displayed through a fluorescent screen. This method has good intuitiveness, strong repeatability, and can be used for comparison before and after. Therefore, it is widely used for the diagnosis of systemic diseases such as obstetrics and gynecology, urology, digestion, and cardiovascular diseases.

M-type: It is a method used to observe the temporal changes of activity interfaces. Suitable for examining the activity of the heart, the dynamic changes in its curve are called echocardiography, which can be used to observe the position, activity status, and structural condition of various layers of the heart. It is often used to assist in the diagnosis of heart and large vessel diseases.

D-type: It is an ultrasound diagnostic method specifically used to detect blood flow and organ activity, also known as Doppler ultrasound diagnostic method. It can determine whether the blood vessels are unobstructed, whether the lumen is narrow, occluded, and the location of the lesion.
