Medical ultrasound scanner is a widely used imaging device for medical diagnosis, which obtains structural and functional information inside the human body through the reflection and propagation of high-frequency sound waves. Although ultrasound examination has many advantages, such as non-invasive and radiation free, its safety considerations and radiation protection issues are becoming increasingly prominent with the increase of usage frequency and the expansion of usage range. This article will explore the safety considerations and radiation protection measures of medical ultrasound scanners.

1、 Safety considerations for medical ultrasound scanners

Equipment Safety

The safety of medical ultrasound scanners is the primary consideration. Manufacturers should ensure that the equipment is designed reasonably, with stable quality and reliable performance to reduce risks during use. At the same time, medical institutions should regularly maintain and inspect equipment to ensure that it is in good working condition.

Operational security

Operating medical ultrasound scanners requires a certain level of professional knowledge and skills. Operators should receive formal training and master the correct operating methods and safety precautions. During the operation, attention should be paid to the safety and comfort of the patient to avoid unnecessary risks.

Image quality and diagnostic accuracy

The image quality and diagnostic accuracy of medical ultrasound scanners have a significant impact on their safety. High quality images can enhance doctors' diagnostic confidence and reduce the possibility of misdiagnosis. Therefore, operators should proficiently master the interpretation skills of ultrasound images to improve diagnostic accuracy.

Patient safety

Patients are the main beneficiaries of medical ultrasound scanners, so their safety is a focus of attention. During the examination process, it is important to ensure that the patient is in a safe environment and avoid accidental injuries caused by improper operation or equipment malfunction. At the same time, operators should pay attention to individual differences in patients, such as special populations (pregnant women, children, etc.) that should take corresponding safety measures.

2、 Radiation protection of medical ultrasound scanners

Radiation characteristics and hazards

Although medical ultrasound scanners do not generate ionizing radiation themselves, high intensity or high-frequency ultrasound may produce thermal and non thermal effects, which have a certain impact on human health. The thermal effect may cause an increase in local tissue temperature, and in severe cases, it may cause burns or damage to sensitive organs. Non thermal effects may affect the function of human cells and organs, and even cause tissue damage or lesions.

Radiation protection measures

In order to reduce the radiation hazards of ultrasound, the following radiation protection measures should be taken:

(1) Limit radiation intensity: Reasonably set the output power and frequency of ultrasound to avoid using excessive sound intensity. At the same time, adjust the sound intensity based on individual differences of patients to ensure a safe range.

(2) Add protective measures: Operators and patients should take appropriate protective measures, such as wearing personal protective equipment such as protective glasses and earplugs, and using protective shields (such as protective clothing and shields) to reduce radiation exposure. For special populations (pregnant women, children, etc.), appropriate protective measures should be added to ensure their safety.

(3) Standardized operating procedures: Operators should strictly follow the operating procedures to avoid prolonged and close contact with patients. At the same time, attention should be paid to observing the patient's reaction during the operation, and if there is any discomfort, the examination should be stopped immediately.

(4) Regular examination and training: Medical institutions should conduct regular health checks on operators to ensure their physical health. At the same time, regular radiation protection training should be conducted to enhance the safety awareness and response ability of operators.

(5) Reasonably layout the diagnosis and treatment environment: Reasonably layout the diagnosis and treatment environment to ensure good ventilation in the diagnosis room and reduce the accumulation of radiation in the space. At the same time, equipment that may generate radiation should be placed in specific protective areas and clearly labeled with warning signs.

Joint consideration with other imaging devices

Medical ultrasound scanners are often used in conjunction with other imaging devices such as X-rays, CT, etc. During use, attention should be paid to radiation protection issues between each other, and appropriate isolation measures should be taken to reduce the impact of cross radiation. At the same time, reasonable layout and zoning should be carried out in accordance with relevant national regulations and standards to ensure the safety of patients and staff.

3、 Conclusion

As an important medical imaging equipment, the safety considerations and radiation protection issues of medical ultrasound scanners cannot be ignored. By improving the performance and quality of equipment, standardizing operator training and management, and adopting effective radiation protection measures, potential risks during use can be reduced, ensuring the safety of patients and staff. In the future development, with the continuous progress and innovation of technology, it is believed that the safety and radiation protection capabilities of medical ultrasound scanners will be further improved.
