Fig. 4: A syrinx model reconstructed from DiceCT scans and the representative 2D lateral vibratory mass (LVM) shapes for training the PINN.

The same type of data and models were generated for other three pigeon syringes. a The photo of the excised syrinx. b A DiceCT scan of the syrinx. One LVM was annotated. c The 3D computational model reconstructed from the DiceCT scans including the pair of LVMs and the surrounding cartilages. A detailed view of the left LVM is shown to the right. The red line shows the mid-coronal cross-section of the LVM. d Representative snapshots of LVMs vibrations during one vibration cycle extracted from high-speed videos. The blue lines denote the 2D profiles of the LVMs which were manually annotated.
