Abstract

This study aims to ensure the effectiveness of medical ultrasound diagnostic equipment in clinical applications by testing multiple key performance indicators using tissue-mimicking phantoms and exploring the changes in these performance indicators over time. Firstly, 17 in-service medical ultrasound diagnostic equipments were selected, and their depth of penetration, dead zone, lateral resolution, axial resolution, geometric position error, and cystic focal diameter error were tested according to the verification regulations. In addition, the study retrospectively analyzed the performance testing data of 19 medical ultrasound diagnostic equipments over the past three consecutive years and conducted statistical analysis. Through the testing, all performance indicators of the 17 equipments met the requirements of the verification regulations, indicating that they can stably and reliably provide high-quality ultrasound diagnostic images and data in clinical applications. Meanwhile, retrospective data showed that with the increase with the increase in service life, the resolving ability at the far field of the 19 equipments decreased, and the cystic focal diameter error increased. Therefore, it is recommended that medical institutions establish a regular testing and maintenance system for medical ultrasound diagnostic equipment, conducting regular performance evaluations and maintenance to ensure its good working condition.

[基于组织模拟的医用超声诊断设备性能测试]。

本研究旨在通过模拟组织模型测试医学超声诊断设备的多个关键性能指标，并探讨这些指标随时间的变化，以确保其在临床应用中的有效性。首先，选取17台在用医用超声诊断设备，根据检定规程对其穿透深度、死区、横向分辨率、轴向分辨率、几何位置误差、囊性病灶直径误差进行检测。此外，本研究对19台医用超声诊断设备连续三年的性能检测数据进行回顾性分析，并进行统计分析。通过测试，17台设备的各项性能指标均达到验证规程的要求，能够稳定、可靠地为临床应用提供高质量的超声诊断图像和数据。同时，回顾性数据显示，随着使用寿命的增加，19台设备的远场分辨能力下降，囊焦直径误差增大。因此，建议医疗机构对医用超声诊断设备建立定期检测和维护制度，定期进行性能评估和维护，确保其良好的工作状态。
