美国食品药品监督管理局（FDA）清除了三个模块的AI-Rad Companion Chest CT，这是来自西门子卫生师（德国Erlangen）的智能软件助理，将人工智能（AI）带到计算机层析成像（CT）。AI-Rad Companion Chest CT代表了新的AI-RAD伴侣平台的第一位智能助手，可帮助放射科医生快速解释胸部（胸部）的图像，并具有所需的准确性和精确度，并自动将这些发现记录为结构化报告。

AI-RAD伴侣胸部CT中的算法已在广泛的数据集上进行了培训，并由合格的临床专家注释，以提供分割，测量和突出关键解剖结构，以支持定量和定性分析。使用胸部的CT图像，AI-RAD伴随的胸部CT在该区域的各个结构（包括肺，心脏和主动脉）之间进行了区分，可以单独突出显示它们，并标记和测量潜在异常，例如冠状动脉钙化。

It supports a variety of tasks, including automated detection of lesions, localization of abnormalities, and measurement of lung lesions; quantification of per-lobe low-attenuation parenchyma; enhanced visualization of lung lesions; automated segmentation of lung lobes and enhanced visualization of low-attenuation parenchyma; segmentation and measurement of maximum diameters of the thoracic aorta; quantification of the total calcium volume in the coronary arteries; and detection of nine anatomical landmarks as identified by American Heart Association (AHA) guidelines.

Based on the AI-supported analysis, AI-Rad Companion Chest CT automatically generates standardized, reproducible, and quantitative reports in Digital Imaging and Communications in Medicine (DICOM) SC format. In addition to reducing time spent on manual results documentation, these reports can be accessed by radiologists on the picture archiving and communication system (PACS) in the clinical routine. AI-Rad Companion Chest CT also highlights potentially clinically relevant changes that might otherwise remain unnoticed because they were not the primary indication for the exam.

“ AI-Rad Companion Chest CT建立在我们在AI和机器学习方面长达数十年的专业知识，数字化医疗保健和帮助提供者以增强的检测，准确性和精度对胸部进行多器官图像解释，从而可以改善结果，从而有可能改善结果。”西门子卫生员的美洲总裁兼负责人戴维·帕西蒂（David Pacitti）说。
