“…The 3D reconstructed CT images can provide stereo-form information to the viewers and further be reviewed at different places by cloud technology. 21 Moreover, a surgeon would perform virtual surgery for practice via computer programs. 22 Instead, printing out a 3D model based on 3D reconstructed CT images can provide a real object to a surgeon even though the printing process is time-consuming and may cost.…”

Background: To surgically remove osteoma and to keep an optimal cosmetic profile would be very challenging. To solve the difficulty, we utilized the three-dimensional (3D) printing technologies in generating a patient-specific instrument guide (PSIG) for the safe removal of a skull bone tumor. Methods: The preoperational brain computed tomography (CT) provided the digital imaging with thin slices, and then images were reconstructed into a 3D skull model. Based on the model, we designed a PSIG to make landmarks on the osteoma to avoid excessive removal of the skull bone. During the operation, the surgeons could remove the osteoma piece by piece by using the landmark as a reference point. Results: The PSIG was successfully applied to remove an osteoma that measured 60 × 48 × 40 mm 3 over the left frontoparietal skull of a female patient. The 3D CT reconstruction taken both before and 4 months after surgery showed a significant change in the appearance of the osteoma. Conclusion: The PSIG was able to guide the surgeon in the safe removal of the skull osteoma, as well as in maintaining the cosmetic skull profile.

“…A projected landmark method for reduction of registration error in image guided surgery systems [74] Tehran University of Medical Sciences Image-guided surgery systems are limited by the registration error, so it is necessary to use practical and effective methods to improve accuracy. In this project, the authors develop and test a method based on the projection point to reduce superficial registration error in guided image surgery.…”

This paper presents a review about neurosurgery, robotic assistants in this type of procedure, and the approach to the problem of brain tissue displacement, including techniques for obtaining medical images. It is especially focused on the phenomenon of brain displacement, commonly known as brain shift, which causes a loss of reference between the preoperative images and the volumes to be treated during image-guided surgery. Hypothetically, with brain shift prediction and correction for the neuronavigation system, minimal invasion trajectories could be planned and shortened. This would reduce damage to functional tissues and possibly lower the morbidity and mortality in delicate and demanding medical procedures such as the removal of a brain tumor. This paper also mentions other issues associated with neurosurgery and shows the way robotized systems have helped solve these problems. Finally, it highlights the future perspectives of neurosurgery, a branch of medicine that seeks to treat the ailments of the main organ of the human body from the perspective of many disciplines.

“…A more dense point cloud was thus acquired by sweeping a projected pattern on the surface. The camera that was used in the present study was the Micron Tracker of Claron, Inc., under Parsiss Image-Guided Navigation 1 , and the software developed in the previous studies conducted by [1,20] were used to filter the outliers and duplicated points.…”

“…Referring to previous works done by author of this paper [1,20], projecting landmarks to visible surface in order to capture a point cloud of surface is an innovative low-cost method that has adequate accuracy for surface registration. Unlike ultrasound images known as noisy data (compared to other modalities) and difficulties of segmentation of anatomic organs, the Doppler US seems to be more suitable for tracking vessels.…”

The proposed projected surface imaging in conjunction with the Doppler US data combined in a powerful biomechanical model can result an acceptable performance in calculation of deformation during surgical navigation. However, the projected landmark method is sensitive to ambient light and surface conditions and the Doppler ultrasound suffers from noise and 3D image construction problems, the combination of these two methods applied on a FEM has an eligible performance.
