Abstract:
Objective: Combined with the metrological verification in order to strengthen the quality control of medical ultrasonic diagnostic instrument, to ensure the image quality of instruments and medical safety. Methods: Measure output sound intensity, patient leakage current, metrological verification parameters detection depth, resolution, geometric position error value, cystic focal diameter error, blind area and so on. Results: Through analyzing the data of metrological verification results, and in combination with the practical situation of hospital ultrasonic diagnostic instrument calibration, approved metrological verification instrument performance detection technology as the basis. Conclusion: The combination of metrological verification, strengthen training, maintenance, etc, to ensure the operation and safety of instruments, to achieve good quality control in the device.
