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。
