Gastrointestinal diseases refer to any disease within or around the gastrointestinal tract. Ultrasound technology is widely used in the diagnosis of gastrointestinal diseases. This article will introduce the technical principles, applications, advantages, and progress of ultrasound scanning in the diagnosis of gastrointestinal diseases, in order to help readers understand the progress in this field.

1、 Technical Principles

Gastrointestinal diseases depend on the shape and location of their tumors, and ultrasound is an easy, safe, and non-destructive method for detecting tumors. Ultrasound scanning diagnoses gastrointestinal diseases. The examiner will use a handheld probe to place it in the patient's abdomen, transmit the ultrasound signal to the patient's body, and then reflect it back. Among them, the probe can detect reflected waves and convert them into electrical signals, which will be sent to a professional software computer to form a high-resolution image to help doctors make the final diagnosis. Here are the specific technical principles:

1. Ultrasonic emission: ultrasonic is a special waveform whose frequency is higher than the normal Hearing range. Therefore, ultrasonic emission frequency and Penetration depth need to be set before ultrasonic emission.

2. Ultrasonic reception: The probe receives the ultrasonic signal. After receiving the ultrasound, the probe will convert it into an electrical signal and transmit it to the computer.

3. Image processing: Computers can process the received ultrasound signals to generate accurate images of gastrointestinal diseases. When displaying images, it is necessary to control the observation range, character size, and color tone of the image to fully display the situation of gastrointestinal tumors.

2、 Applications and advantages

Ultrasound scanning is widely used in clinical practice and is a commonly used method for detecting gastrointestinal diseases. Ultrasonic diagnostic technology has many obvious advantages, as follows:

1. Non invasive and painless: Compared to other imaging examinations, ultrasound scanning does not require stimulation and injection, and does not cause trauma or pain to patients.

2. High precision and resolution: Ultrasonic scanning is excellent in visual effects, with better clarity and resolution.

3. Fast, real-time, and multi angle: Ultrasound scanning can quickly achieve multi angle scanning, fully examine the condition of tumors, and display relevant image information in real time.

4. Economical, easy to operate, and easy to repeat: The cost of ultrasonic scanning is relatively low, and the economic cost is also relatively low. It has strong operability, is easily accepted by clinical doctors, and is easy to be repeatedly applied.

In clinical practice, ultrasound scanning is one of the commonly used methods for diagnosing gastrointestinal diseases. It is widely used in the following areas:

1. Digestive tract tumors: Ultrasound scanning can effectively detect the size, location, and morphology of digestive tract tumors, especially for the early diagnosis of gastric cancer.

2. Gallstone: Ultrasonic scanning is more common in the diagnosis of Gallstone. It can identify whether persimmons have Cholecystitis and gallbladder disease by detecting whether persimmons have water, size, location, shape and other information.

3. Other gastrointestinal diseases: ultrasonic scanning is also used to detect and judge other gastrointestinal diseases, such as intestinal obstruction, appendicitis, anal pruritus, anal fissure, etc.

3、 Progress

With the convenience and development of information technology, ultrasonic scanning technology has been constantly updated and developed. The new technology has successfully achieved "three-dimensional" imaging of gastrointestinal tumors using ultrasound in Beijing, which can simultaneously display three-dimensional images and image components to comprehensively understand abnormal conditions in the gastrointestinal tract.
