 - 中间序列列表：从已处理 DICOM 目录扫描 DICOM 头信息。
-- 右侧查看器：支持横断面、矢状面、冠状面，窗宽窗位、旋转、切片进度条。
+- 右侧查看器：支持轴位原始、矢状位重建、冠状位重建，窗宽窗位、旋转、切片进度条。
 - 影像操作：支持鼠标滚轮缩放、拖拽平移、按钮缩放和复位。
+- 图像叠层：可显示/隐藏患者、检查、方向、张数、窗宽窗位和缩放信息。
 - DICOM 信息：查看患者、检查、序列、像素间距、切片间距等元数据。
-- 序列标注：选择略过、头颈部、胸部、上腹部、下腹部、盆腔；上腹部需继续选择动脉期、门静脉期或无法判别。
+- 序列列表：默认按拍摄时间升序排序，可切换降序；少于 80 张且未标注部位的序列默认略过。
-- AI 识别：配置 Kimi 后，可把序列张数及横断面、矢状面、冠状面代表图像传入 AI，自动给出部位、期相和备注建议。
