Surgical Planning
Surgical planning is the preoperative method of pre-visualising a surgical intervention, in order to predefine the surgical steps and furthermore the bone segment navigation in the context of computer-assisted surgery. The surgical planning is most important in neurosurgery and oral and maxillofacial surgery. The transfer of the surgical planning to the patient is generally made using a medical navigation system. __TOC__ Principles of surgical planning The imagistic dataset used for surgical planning is mainly based on a CT or MRI. In oral and maxillofacial surgery, a different, more "traditional" surgical planning can be used for orthognatic surgery, based on cast models fixed into an articulator. History of the concept In order to make a surgical planning, one would need a 3D image of the patient. The starting point was made by G. Hounsfield in the 1970s, by using CT in order to record data about the anatomical situation of the patients. In the 1980s, advances were ...

Computed Tomography
A computed tomography scan (CT scan; formerly called computed axial tomography scan or CAT scan) is a medical imaging technique used to obtain detailed internal images of the body. The personnel that perform CT scans are called radiographers or radiology technologists. CT scanners use a rotating X-ray tube and a row of detectors placed in a gantry to measure X-ray attenuations by different tissues inside the body. The multiple X-ray measurements taken from different angles are then processed on a computer using tomographic reconstruction algorithms to produce tomographic (cross-sectional) images (virtual "slices") of a body. CT scans can be used in patients with metallic implants or pacemakers, for whom magnetic resonance imaging (MRI) is contraindicated. Since its development in the 1970s, CT scanning has proven to be a versatile imaging technique. While CT is most prominently used in medical diagnosis, it can also be used to form images of non-living objects. The 1979 Nob ...

Radiology
Radiology ( ) is the medical discipline that uses medical imaging to diagnose diseases and guide their treatment, within the bodies of humans and other animals. It began with radiography (which is why its name has a root referring to radiation), but today it includes all imaging modalities, including those that use no electromagnetic radiation (such as ultrasonography and magnetic resonance imaging), as well as others that do, such as computed tomography (CT), fluoroscopy, and nuclear medicine including positron emission tomography (PET). Interventional radiology is the performance of usually minimally invasive medical procedures with the guidance of imaging technologies such as those mentioned above. The modern practice of radiology involves several different healthcare professions working as a team. The radiologist is a medical doctor who has completed the appropriate post-graduate training and interprets medical images, communicates these findings to other physicians ...

Volume Interactions Pte Ltd
Volume Interactions Pte Ltd was a company that pioneered in the 1990s the use Virtual Reality technology in surgery planning. The company created and marketed the Dextroscope, the first commercial surgical planning system that used virtual reality principles going beyond the mouse and keyboard. The Dextroscope introduced a variation of Virtual Reality technology that didn't use Head-Mounted display (using instead a stereoscopic display that housed a two-handed 3D user interface) that provided a natural and comfortable interface to work with multi-modality 3D medical images for long periods of time. This environment was applied to the planning of patient-specific surgical approaches for several clinical disciplines, including neurosurgery, Ear-Nose-Throat, and liver surgery. The Dextroscope received world-wide attention by being involved in the planning of several craniopagus twin separations, most notably the Zambian twins (1997) and the German twins (2004) at Johns Hopkins Hos ...

Virtual Reality
Virtual reality (VR) is a simulated experience that employs pose tracking and 3D near-eye displays to give the user an immersive feel of a virtual world. Applications of virtual reality include entertainment (particularly video games), education (such as medical or military training) and business (such as virtual meetings). Other distinct types of VR-style technology include augmented reality and mixed reality, sometimes referred to as extended reality or XR, although definitions are currently changing due to the nascence of the industry. Currently, standard virtual reality systems use either virtual reality headsets or multi-projected environments to generate realistic images, sounds and other sensations that simulate a user's physical presence in a virtual environment. A person using virtual reality equipment is able to look around the artificial world, move around in it, and interact with virtual features or items. The effect is commonly created by VR headsets consisting ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Osteotomy
An osteotomy is a surgical operation whereby a bone is cut to shorten or lengthen it or to change its alignment. It is sometimes performed to correct a hallux valgus, or to straighten a bone that has healed crookedly following a fracture. It is also used to correct a coxa vara, genu valgum, and genu varum. The operation is done under a general anaesthetic. Osteotomy is one method to relieve pain of arthritis, especially of the hip and knee. It is being replaced by joint replacement in the older patient. Due to the serious nature of this procedure, recovery may be extensive. Careful consultation with a physician is important in order to ensure proper planning during a recovery phase. Tools exist to assist recovering patients who may have non–weight bearing requirements and include bedpans, dressing sticks, long-handled shoe-horns, grabbers/reachers and specialized walkers and wheelchairs. Osteotomies of the hip Two main types of osteotomies are used in the correction of hip d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Laboratory Unit For Computer Assisted Surgery
Laboratory Unit for Computer Assisted Surgery is a system used for virtual surgical planning. Starting with 1998, LUCAS was developed at the University of Regensburg, Germany, with the support of the Carl Zeiss Company. The resulting surgical planning is then reproduced onto the patient by using a navigation system. In fact, LUCAS is integrated into the same platform together with the Surgical Segment Navigator (SSN), the Surgical Tool Navigator (STN), the Surgical Microscope Navigator (SMN) and the 6 DOF Manipulator (or, in German, "Mehrkoordinatenmanipulator" - MKM), also from the Carl Zeiss Company. __TOC__ Workflow Data from separate bidimensional slices generated by a CT or MRI scan are uploaded into the LUCAS system. The resulting dataset is then processed, in order to eliminate image noise, and to enhance the anatomical contours and also the general contrast of the images. The next step is to create a virtual 3D model from the gathered collection of 2D images. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
