撰文丨王聪 编辑丨王多鱼 排版丨水成文 该研究受 生成式人工智能 （generative AI ） 的启发，提出了 一种通用于 DSA 设备的 生成式人工智能低 剂量成像系统 —— GenDSA 。 该系统生成的 DSA 视频序列仅需使用 1/3 的扫描帧率就能生成与全帧率 几乎一致的视频序列。 使用 GenDSA 系统后，辐射剂量可降低至临床现有方案的 1/3，而不影响临床诊疗 效率 。 数字减影血管造影 （ Digital subtraction angiography， DSA） 设备广泛应用于多种疾病的介入治疗指 导，全球每日接受该检查的患者超过 10 万人次。然而，此类操作每次都需要多次扫描，会使患者及医务人 员暴露于 电离辐射 ，增加健康风险。尽管已有多种低剂量 DSA 成像技术被提出，但均未经过前瞻性临床 验证。 2026 年 1 月 2 日，华中科技大学同济医学院附属协和医院 郑传胜 、华中科技大学电子信息与通信学院 王兴刚 、武汉大学计算机学院 杜博 、 华盛顿大学医学院 朱成成 、 华中科技大学同济医学院附属协和医 院 阚雪锋 、 赵 煌旋 等人在 Nature Medicine 期刊发表 ...

Core Viewpoint - The production of solar cells in China is projected to reach 680 million kilowatts in 2024, representing a year-on-year growth of 15.7%, while concerns about harmful electromagnetic radiation from solar panels are addressed as unfounded [1][8]. Group 1: Solar Cell Production and Technology - China's solar cell production is expected to reach 680 million kilowatts in 2024, with a growth rate of 15.7% compared to the previous year [1]. - Solar photovoltaic cells convert sunlight directly into electricity through the photovoltaic effect, producing a voltage and current when illuminated [1][2]. Group 2: Electromagnetic Radiation Concerns - Solar panels emit weak electromagnetic radiation, which is not ionizing radiation and is considered harmless to human health [2][6]. - The electromagnetic radiation produced by solar panels is significantly lower than that of common household appliances and communication devices [5][6]. - The World Health Organization's recommended public exposure limit for magnetic fields is 100 microteslas, while the radiation from photovoltaic systems is well below this threshold [6]. Group 3: Comparison with Other Technologies - Solar water heaters operate differently from solar panels, converting sunlight directly into heat without generating electromagnetic waves, thus posing no radiation concerns [9]. - The primary emissions from solar panels are light and thermal radiation, which are manageable and not harmful under normal usage conditions [6][8].
