Echocardiography is a non-invasive medical examination technique that helps doctors understand the structure and function of the heart by generating real-time cardiac images using medical ultrasound scanners. In clinical practice, echocardiography has become one of the preferred methods for evaluating heart disease. This article will provide a detailed introduction to how to use a medical ultrasound scanner to perform echocardiography on the heart.

1、 The principles of ultrasound and the advantages of echocardiography

Medical ultrasound scanner is a device that uses high-frequency sound waves to generate images. When ultrasonic signals pass through human tissues, sound waves are reflected, scattered, refracted, and absorbed. These signals are processed and amplified by instruments to generate clear heart images.

Compared with other cardiac examination methods, echocardiography has many advantages. Firstly, it is a non-invasive examination method that is non radioactive and harmless to patients. Secondly, echocardiography can provide real-time images, allowing doctors to observe the movement of the heart and blood flow. In addition, echocardiography is easy to operate and has a lower cost.

2、 Preparation work

Before conducting an echocardiography examination, some preparatory work is required. Firstly, the patient needs to remove their coat so that the doctor can better observe the heart. Secondly, the doctor will apply a layer of conductive gel on the patient's chest to ensure the transmission effect of ultrasound. Finally, the patient needs to lie down and maintain a relaxed state for the doctor to examine.

3、 Echocardiography examination process

Echocardiography examination includes the following steps:

1. Select the appropriate probe and image mode

Medical ultrasound scanners are usually equipped with various types of probes, and doctors choose the appropriate probe based on the specific situation of the patient. At the same time, different image modes can also be selected according to needs, such as two-dimensional mode, color Doppler mode, etc.

2. Positioning and adjusting the settings of the ultrasonic scanner

The doctor needs to place the ultrasound scanner on the patient's chest and make appropriate adjustments as needed to obtain the clearest cardiac image.

3. Obtain images

The doctor will move the probe onto the patient's chest and gradually scan the different structures of the heart. During the scanning process, doctors can make adjustments as needed to obtain the desired image.

4. Analysis and Evaluation Results

Once the image is obtained, the doctor will analyze and evaluate it. They will observe the size, shape, and structure of the heart, and examine its systolic and diastolic functions. In addition, doctors can also evaluate blood flow and detect the presence of valve diseases or cardiovascular abnormalities.

4、 Precautions

When using a medical ultrasound scanner for cardiac echocardiography, there are some precautions to note:

1. There is no pain during the inspection process and no need to worry.

During the examination process, it is necessary to cooperate with the doctor's instructions and try to maintain calm and relaxation.

If you have any questions or discomfort, please inform the doctor promptly.

Conclusion:

Medical ultrasound scanner is an effective, safe, and non-invasive tool that plays a crucial role in cardiac echocardiography examination. Through the application of echocardiography, doctors can accurately evaluate the structure and function of the heart, providing patients with better diagnosis and treatment plans. With the continuous progress of medical technology, it is believed that echocardiography will play a more important role in clinical practice.
