基于2025年上海市医疗机构超声诊断设备基线调查数据，分析全市医疗机构超声设备配置现状、品牌分布、性能状况及质量控制管理关键问题，提出针对性优化策略。

依托上海市超声质量控制督查平台，收集辖区内医疗机构自主上报的超声诊断设备基线数据，覆盖上海市599家公立及民营医疗机构，统计有效超声设备2770台。分析超声设备品牌型号、各级医疗机构配置差异、购置年份与性能及使用范围分布等核心指标。

上海市超声设备以飞利浦、通用电气、迈瑞、西门子为主要品牌，合计占据71.3%的市场份额；国产品牌迈瑞设备优良率达97.3%，平均使用年限为3.4年，市场发展迅速。设备配置呈现明显梯度差异，三级甲等医院平均每家拥有超声设备19.7台，非三级医疗机构及其他医疗机构每家仅拥有超声设备2.1~6.2台。全市设备平均使用年限为5.5年，9.9%（273/2770）的设备使用超过10年，老旧设备优良率仅为78.2%~84.0%。质量控制管理存在分布不均、型号碎片化、评估标准不统一等问题。

需通过建立分级分类更新机制、推动标准化信息化管理、加强基层配置支持及完善质量控制监测体系，全面提升上海市超声诊断设备质量控制管理水平。

Based on baseline survey data of ultrasound diagnostic equipment in medical institutions in Shanghai in 2025, this study aimed to analyze the current status, brand distribution, performance status, and key quality control management issues of ultrasound equipment across the city.

Using the Shanghai Ultrasound Quality Control Supervision Platform, we collected baseline data voluntarily reported by local medical institutions, covering 599 public and private medical institutions. A total of 2770 effective ultrasound devices were included. Core indicators, including equipment brand and model, configuration differences across institutional levels, correlation between purchase year and performance, and distribution of usage scope, were analyzed.

Philips, General Electric, Mindray, and Siemens were the dominant ultrasound equipment brands in Shanghai, together accounting for 71.3% of the market share. The excellent-or-good rate of the domestic brand Mindray was 97.3%, with an average service life of 3.4 years, indicating rapid market growth. Equipment configuration showed significant gradient disparities: tertiary grade-A hospitals averaged 19.7 ultrasound devices each, while non-tertiary and other medical facilities had only 2.1-6.2 devices. The citywide average service life was 5.5 years, with 9.9% (273/2770) of devices used for more than 10 years; the excellent-or-good rate of these older devices was only 78.2%-84.0%. Identified quality control management issues included uneven distribution, fragmented device models, and inconsistent evaluation standards.

To comprehensively enhance the quality control management of ultrasound diagnostic equipment in Shanghai, it is necessary to establish a tiered update mechanism, promote standardized information management, strengthen primary-care equipment support, and improve the quality control monitoring system.
