Intensity-Based 2D-3D Spine Image Registration Incorporating One Fiducial Marker

Abstract

Abstract. In this paper, we propose a hybrid similarity measure for 2D-3D image registration that is a weighted combination of an intensitybased image similarity measure and a point-based measure incorporating a single fiducial marker. We evaluate its accuracy and robustness using gold-standard clinical spine image data. The use of one fiducial marker substantially improves registration accuracy and robustness.

Non-invasive, fluoroscopy-based, image-guided surgery reduces radiation exposure for vertebral compression fractures: A preliminary survey

“…However, artificial markers usually require a surgical implantation procedure and is considered too invasive to be clinically acceptable. 12 Conventional fluoroscopy-based image guidance systems usually include a computer system, a C-arm fluoroscope, dynamic reference frames, and customized surgical instruments that can be tracked by the systems. 7 One disadvantage of the conventional system is the need for a procedure that exposes another spinous process or requirement of percutaneous pin fixation in the posterior iliac crest for DRF attachment.…”

Computer-assisted fracture reduction of proximal femur using preoperative CT data and intraoperative fluoroscopic images

“…The 3D positional constraint of the proximal fragment is obtained from the hip joint rotation center, which is supposed to correspond to the femoral head center of the proximal fragment. By combining the constraint of the hip joint rotation center with that of 2D/3D registration, we define the hybrid similarity measure [4] as…”
