Comparative study of ultrasound shape completion and CBCT-based AR workflows for spinal needle interventions

1

Ultrasound offers radiation-free, real-time imaging for spinal interventions, addressing limitations of conventional methods like fluoroscopy and CT.
2

Recent advancements in ultrasound shape completion enable accurate 3D reconstruction of lumbar vertebrae from partial ultrasound inputs, enhancing visualization.
3

Augmented reality (AR) improves spatial awareness and ergonomics in spine surgery, reducing cognitive load and radiation exposure during procedures.
4

This study compares ultrasound-based and CBCT-based AR workflows for spinal needle guidance, evaluating visualization accuracy and anatomical fidelity.
5

Integrating dynamic ultrasound reconstructions into AR could provide real-time, patient-specific visualization, enhancing the safety and efficacy of spinal interventions.
