SyCaR Framework Improves Geometric Consistency in Dual-Arm Robotic CBCT

Synergistic calibration & PD-FDK reconstruction improved PSNR (28.99→32.72 dB) and RMSE (0.036→0.023) in dual-arm robotic CBCT phantoms. Single-system; not yet clinically validated.

• Numerical and physical phantom study (sample size not specified) evaluated a two-stage calibration plus pose-driven FDK reconstruction.
• PD-FDK vs. standard FDK: PSNR improved from 28.99 dB to 32.72 dB, RMSE reduced from 0.036 to 0.023.
• Limitation: validation limited to a single system and phantom settings; broader trajectory and clinical data needed.
