Registration of 3D CT and ultrasound datasets of the spine using bone structures

Abstract: A robust algorithm for the registration of 3D CT and ultrasound datasets is presented. The computation time seems sufficiently short to permit intraoperative use.

“…In a sagittal slice, a string of transverse processes appeared representing the curvature of the spine. They are comparable to the ultrasound images shown in [3,16]. The appearance of the vertebral features is necessary to enable determination of the position and orientation of each vertebra in 3D space and the curvature of the spine.…”

“…Parts perpendicular to the beam direction deliver a strong signal, while the others provide a weak signal or no signal at all [3]. If the scan is performed from the back of the human body, several parts of the vertebrae such as transverse processes, laminae, and spinous processes can be captured as shown in Fig.…”

“…In addition, ultrasound images show only a small part of the target surface. Finally, nearly all ultrasound waves are reflected at the tissue‐bone interface, so imaging is not possible beyond that interface16.…”

“…[11][12][13][14][15][16] Moreover, studies [17][18][19][20][21][22] have demonstrated that clinical ultrasound (CUS) could be used to locate and identify the posterior arches of the spine ( i.e ., lamina, spinous process), and using this approach the SPA can be measured. Spinous process angle (SPA), formed by accumulating the angles formed by every 2 lines joining 3 neighboring spinous processes, has also been described.…”
