文兴：政策托底 A股进入结构性重估期超声探头导航基准发现现成方法组合仍难靠近目标
USB Gym把超声导航拆成三个可替换环节，识别器官、决定探头如何移动，以及评价当前画面与目标有多接近。团队用公开患者CT生成模拟超声，把20种已有方法放入同一测试环境，在六名留出患者的60轮任务中比较。只有观察到更好表现的部件才替代原方案，之后再用20份新CT检验组合结果。 Thanapong Intharah等人的这项研究收录在11月6日更新的计算机科学预印本列表中。
起始位置平均距目标切面16毫米，能直接读取真实探头姿态的仿真参照方法把误差降至1.5毫米。最终基准方案仅将距离缩至13.7毫米，约完成参照方法进展的16%。入选组合中，主要变化是以图像结构相似度作为奖励。作者将结果标为探索性，全部操作都在仿真环境中完成，尚未在真实超声设备上试验。
