Ultrasound emitted by veterinary B ultrasound is generally not harmful to animals. Of course, usually we say ultrasonic radiation dose refers to the product of ultrasonic intensity and radiation time. The working principle of veterinary B-ultrasound instrument is to emit a beam of high-frequency ultrasonic pulse waves into the animal body. After the sound wave radiation, different waveforms are reflected back from different interfaces in the animal body to generate veterinary B-ultrasound images, so as to judge the lesions in the animal body. When the ultrasonic dose in the animal tissue is too small to detect the lesions in the animal body, the diagnosis of veterinary B-ultrasound is meaningless. Therefore, it is of great significance to control the dose of ultrasonic source reasonably

The first is the dose control of veterinary B-ultrasound in normal inspection, the control of ultrasonic waveform and ultrasonic irradiation time of veterinary B-ultrasound. The ultrasonic waveform with short pulse width should be preferred in the usual inspection. Its advantage is that the average sound intensity is relatively low. Compared with continuous ultrasonic waveform, this ultrasonic waveform is relatively safe.

Clinical normal diagnostic examination, ultrasonic radiation time is controlled at about 10 minutes, individual special diagnostic examination, pulse wave ultrasonic source irradiation time should be controlled within 30 minutes. Ultrasonic intensity control. In the application of veterinary B-ultrasonography in veterinary clinical diagnostic examination, the ultrasonic intensity should be reasonably selected, and the ultrasonic intensity should be reduced as far as possible to achieve the interaction between the ultrasonic wave and the animal tissues when it is transmitted in the animal body, without harming the animal health of the patient.

Therefore, more and more attention has been paid to the requirement of rational use of ultrasonic radiation dose and diagnostic image quality. In order to ensure the safety and accuracy of diagnostic results during animal inspection and avoid medical accidents caused by missed diagnosis and misdiagnosis, the ultrasonic dose of veterinary B-ultrasound has been controlled through repeated tests during production.
