"""
為每個 (volume, level) 的骨頭遮罩（{level}_binary_sdf.nii.gz，缺則 _binary）繪製
X-ray 四視角圖（不畫螺絲），存到 Output/{date}/{volume}/。

輸出檔名：{volume} {level}_CBT.png
（例：1.3.6.1.4.1.9328.50.4.0005 L1_CBT.png）

Usage:
  python xfr_plot_level.py                     # 全部 volume 的 L1~L5
  python xfr_plot_level.py 0005                # 該 volume 的 L1~L5
  python xfr_plot_level.py 0005 L1             # 單一 (volume, level)
  python xfr_plot_level.py --dir <standardized_dir> --output <output_base>
