Gold Standard or Reference Standard (The clinical reference standards required to establish the presence or absence of the target condition in the tested population in present study):

Routine ultrasound to confirm the diagnosis of lower limb venous thrombosis.

指标试验(即本研究的待评估诊断试验,无论为方法、生物标志物或设备,均请列出名称):

待评估的诊断试验:贴片式超声监测设备结合人工智能算法,用于自动扫查和实时处理动态超声数据,以识别下肢深静脉血栓(DVT)。 设备名称:贴片式超声监测设备(已获得国家二类医疗器械注册证:川械注准20242060267)。 方法:通过贴片式超声设备采集下肢静脉的超声图像,结合人工智能算法对图像进行分析,实现DVT的自动识别和预警。

Index test:

Diagnostic test to be evaluated: patch ultrasound monitoring device combined with artificial intelligence algorithms for automatic sweeping and real-time processing of dynamic ultrasound data to identify deep vein thrombosis (DVT) in the lower limbs. Device name: Patch-type ultrasound monitoring device (has obtained the national Class II medical device registration certificate: ChuanMeIuZhuQi20242060267). Methods: The ultrasound images of lower limb veins were acquired by the patch ultrasound device, and the images were analysed by combining with artificial intelligence algorithms to achieve automatic identification and early warning of DVT.

目标人群(可以是某种疾病患者或正常人群,详细描述其疾病特征,注意应纳入符合分布特点的全序列病例,具有良好的代表性)
