“…It consists in matching two sets of points: one is defined preoperatively in the model from the 3DSlicer software (virtual model) and another one is collected intraoperatively by the surgeon resorting to the pointer tool in the patient's anatomical structure (physical model). Once some anatomical regions are hard to reach with precision by the pointer tool, the surface registration will provide a better outcome from registration when applied after point-to-point registration [4].…”

-The introduction of the surgical navigation system in the operating room has brought a great development to the surgeries. Nowadays, the navigated surgeries are present in several fields of medicine. This is a technology that requires an optical tracking system to perform the registration procedure during an intraoperative situation. The preoperative plan consists in performing a 3D reconstruction of the treated region and planning all procedures during the surgery. The registration is an important procedure once it calculates the transformation between the coordinate system of the preoperative plan on the software and the coordinate system of the surgical room in order to be able the visualization of the position and orientation of the surgical instruments in relation to the 3D model obtained in the preoperative plan. A workflow in 3DSlicer software to perform the registration procedure is presented in this paper with all required steps to achieve the navigated surgery. Also, it is presented the results obtained from the registration in order to evaluate the procedure.

“…It defines the distance between the landmark on the CT dataset and the coordinates indicated by the tracking system when pointing to the corresponding landmark which was not used for registration [13,14]. Current data comparing different registration modes in electromagnetic tracking suggest that point by point registration using bone anchored fiducials results in lowest TRE, i.e.…”

Purpose: We evaluated the accuracy of surface registration with and without additional landmark registration during cranial electromagnetic navigation. Results were referenced to point by point registration with bone anchored fiducials. Methods:Using a commercially available electromagnetic navigation system, 4 rhinologic surgeons applied surface registration alone (SurfReg) and surface registration with additional anatomic landmarks (CombReg) in a macerated human skull. Point by point registration using bone anchored fiducials (RefReg) served as reference. Target registration error (TRE) served as a measure for accuracy. For TRE calculation, 16 landmarks on the viscerocranium, the frontal skull base and the middle cranial fossa were touched with a probe and the distance of the probe and the target was measured on a screenshot of the corresponding CT image in three planes. A mixed regression model with registration mode as fixed factor and examiner and target as random factors was used.Results: Mean (95% CI) TRE for SurfReg was 1.12 (0.86 to 1.39) mm and 1.21 (0.94 to 1.47) mm for CombReg (p=0.13). TRE of the RefReg was significantly lower (0.91 mm; 0.64 to 1.18; p<0.001). TRE varied significantly depending on target screw position. TRE did not vary significantly among different examiners. Conclusion:Surface registration is considered sufficiently accurate for clinical application during FESS and frontal skull base surgery. Additional landmarks did not improve accuracy when compared with surface registration alone. Additional time for landmark registration can therefore be spared.

“…Currently the dominant imaging modalities used in CAOS are pre-operative X-ray, computed tomography (CT) and magnetic resonance imaging (MRI) and intra-operative two- (2D) or three- (3D) dimensional fluoroscopy (fluoro-CT) 5,9–12 . Due to the superior bone imaging quality, CT is the preferred pre-operative modality used for planning the intervention 11,12 .…”

Due to its real-time, non-radiation based three-dimensional (3D) imaging capabilities, ultrasound (US) has been incorporated into various orthopedic procedures. However, imaging artifacts, low signal-to-noise ratio (SNR) and bone boundaries appearing several mm in thickness make the analysis of US data difficult. This paper provides a review about the state-of-the-art bone segmentation and enhancement methods developed for two-dimensional (2D) and 3D US data. First, an overview for the appearance of bone surface response in B-mode data is presented. Then, classification of the proposed techniques in terms of the image information being used is provided. Specifically, the focus is given on segmentation and enhancement of B-mode US data. The review is concluded by discussing future directions of research and additional challenges which need to be overcome in order to make this imaging modality more successful in orthopedics.
