New scheme for performance evaluation of digital acquisition medical devices

There is still room for improvement in the calibration process of digital acquisition devices. Firstly, the specific indicators still use the method of quantification based on the critical points of intervals, which lacks rigor. Secondly, some test results rely on manual interpretation, which inevitably introduces measurement errors and seriously affects the accuracy of the evaluation results. Therefore, this study introduces more performance indicators that are recognized by the testing industry and can be quantified digitally, proposing a more scientific testing method that is also compatible with current metrological testing standards. This method achieves standardization and comprehensiveness of the performance evaluation criteria for acquisition devices, thereby ensuring the accuracy and credibility of the evaluation results.
