Ectopic pregnancy is a common gynecological disease that has received much attention due to its serious impact on women's health and fertility. Medical ultrasound scanner, as a non-invasive, safe, and efficient examination tool, plays a very important role in the diagnosis of ectopic pregnancy. This article will provide a detailed introduction to the principles, technical characteristics, and application of ultrasound scanners in the diagnosis of ectopic pregnancy.

1、 The principle of ultrasonic scanner

The principle of ultrasonic scanners is to use the reflection and attenuation of ultrasound between different tissues to obtain image information. The ultrasonic scanner consists of three parts:

launcher

The transmitter is the core part of an ultrasonic scanner, which can generate high-frequency (usually 2 to 18MHz) ultrasound. Ultrasound is converted into mechanical vibrations through a transmitter, and then enters the body through the skin.

reflector

Reflectors refer to various tissues and organs of the human body, where ultrasound is reflected at their boundaries and captured by the receiver on the return journey. According to different material densities and structural characteristics, their reflection intensity and time of ultrasound vary, so we can judge the properties of body tissues based on the reflection situation.

receiver

The receiver is responsible for converting the reflected signal into an electrical signal and handing it over to the computer for processing. After processing, the computer can generate a clear and accurate image of the human body structure.

2、 Technical characteristics of ultrasonic scanners

Compared to other medical imaging technologies such as X-ray and CT, ultrasound scanners have the following unique technical characteristics:

Non invasive

Ultrasonic scanners do not require puncture or injection of large doses of radioactive substances, therefore they will not cause damage to human tissues.

High security

Ultrasonic scanners use sound waves instead of electromagnetic waves, so they do not generate ionizing radiation on the human body and have higher safety.

Easy to operate

Ultrasonic scanners are simple to use, do not require special equipment or venues, and have a short examination time, making them suitable for widespread application in various medical institutions.

Low cost

Compared to other medical imaging technologies, ultrasound scanners have lower equipment and material costs, making them suitable for medical institutions of various economic levels.

3、 Application of ultrasound scanner in the diagnosis of ectopic pregnancy

Extrauterine pregnancy refers to the implantation and growth of zygote outside the uterus, rather than in the uterus. If left untreated, ectopic pregnancy can lead to serious consequences such as irreversible fallopian tube injury, massive bleeding, and even death. Therefore, early detection and accurate diagnosis of ectopic pregnancy are very important.
