Abstract：Objective To develop a preventiove maintenance of the HITACHI ARIETTA60 ultrasonic imaging system’s imaging
function. Methods A software that could estimate the signal to noise ration (SNR) of the ultrasonic images from the HITACHI
ARIETTA60 ultrasonic imaging system in Matlab was developed. Then a statistical test model was built by conducting analysis
on the distribution of SNR. Results It was found that the ultrasonic image signal-to-noise ratio of ARIETTA60 was in a normal
distribution. And the paired-samples t model in three sample of SNR from normol images was developed. Conclusion This model
can be used to detect the imaging function of Hitachi ARIETTA60 ultrasound imaging system.
