patient is created or the application mode is changed, the system will retrieve the
default settings. You can also reset the parameters.
6.2.5 ALARA
It is required to practice ALARA when using ultrasound energy. Practicing ALARA
ensures that the total energy level is controlled below a low level at which bioeffects
are not generated while diagnostic information is being accumulated. The total
energy is controlled by output intensity and total radiation time. The output intensity
necessary for examinations differs depending on the patient and clinical case.
Not all examinations can be performed with an extremely low level of acoustic
energy. Controlling the acoustic level at an extremely low-level leads to low-quality
images or insufficient Doppler signals, adversely affecting the reliability of the
diagnosis. However, the sound power which is used greater than the actual needs
does not contribute to improving the quality of diagnostic information either, it will
increase the risk of biological effects.
The operator must take responsibility for the safety of patients.
6.3 Electromagnetic Compatibilities
Electromagnetic compatibilities are the abilities of the system or equipment to operate normally
in the electromagnetic environment and not to radiate any electromagnetic interruptions to any
other objects which are in the same environment.
This system is designed in accordance with the current EMC requirement. And the
ultrasound image will degrade instantly if the system is used in the electromagnetic
field environment. If the degradation of the image is found, it is recommended to
inspect the operation environment to confirm the radiation source.
6.3.1 Electromagnetic Emission
