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] |
Joseph And Luka Banda
Joseph Banda and Luka Banda (born 23 January 1997) are twin brothers who used to be conjoined. They were born joined at the back of the skull and faced in opposite directions. In 1997, neurosurgeon Ben Carson led a team of 50 Zambian and South African specialists to separate the 11-month-old twins in a 28-hour operation. They did not share any organs, but shared intricate blood vessels that flowed into each other's brains. In 2001, the twins were fitted with artificial skulls to permanently close their heads. In an interview, Carson stated about the operation: :"In the end, the Bandas became the first Type 2 craniopagus twins Craniopagus twins are conjoined twins that are fused at the cranium. The union may occur on any portion of the cranium, but does not primarily involve either the face or the foramen magnum; their brains are usually separate, but they may share ...

Singapore
Singapore (), officially the Republic of Singapore, is a sovereign island country and city-state in maritime Southeast Asia. It lies about one degree of latitude () north of the equator, off the southern tip of the Malay Peninsula, bordering the Strait of Malacca to the west, the Singapore Strait to the south, the South China Sea to the east, and the Straits of Johor to the north. The country's territory is composed of one main island, 63 satellite islands and islets, and one outlying islet; the combined area of these has increased by 25% since the country's independence as a result of extensive land reclamation projects. It has the third highest population density in the world. With a multicultural population and recognising the need to respect cultural identities of the major ethnic groups within the nation, Singapore has four official languages: English, Malay, Mandarin, and Tamil. English is the lingua franca and numerous public services are available only in Eng ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Stereoscopy
Stereoscopy (also called stereoscopics, or stereo imaging) is a technique for creating or enhancing the illusion of depth in an image by means of stereopsis for binocular vision. The word ''stereoscopy'' derives . Any stereoscopic image is called a stereogram. Originally, stereogram referred to a pair of stereo images which could be viewed using a stereoscope. Most stereoscopic methods present a pair of two-dimensional images to the viewer. The left image is presented to the left eye and the right image is presented to the right eye. When viewed, the human brain perceives the images as a single 3D view, giving the viewer the perception of 3D depth. However, the 3D effect lacks proper focal depth, which gives rise to the Vergence-Accommodation Conflict. Stereoscopy is distinguished from other types of 3D displays that display an image in three full dimensions, allowing the observer to increase information about the 3-dimensional objects being displayed by head and eye mov ...

Dextrobeam
The Dextrobeam is a highly interactive console that enables collaborative examination of three-dimensional (3-D) medical imaging data for planning, discussing, or teaching neurosurgical approaches and strategies. The console is designed to work in combination with a 3D stereoscopic display. The console enables two-handed interaction by means of two 6 Degree-of-Freedom motion tracking devices. A set of built-in software tools gives users the ability to manipulate and interact with patients’ imaging data in a natural and intuitive way. The stereoscopic display (a large monitor or a projector) displays volumetric 3D medical structures from patients’ multimodality images allowing groups, large and small, to gain a deeper understanding of complex anatomical relationships. The Dextrobeam was used as a teaching tool at the following congresses and courses: The Dextrobeam was installed at the following institutions: {, class="wikitable" , - !

Craniopagus Twins
Craniopagus twins are conjoined twins that are fused at the cranium. The union may occur on any portion of the cranium, but does not primarily involve either the face or the foramen magnum; their brains are usually separate, but they may share some brain tissue. Conjoined twins are genetically identical and always share the same sex. The thorax and abdomen are separate and each twin has its own umbilicus and umbilical cord. The condition is extremely rare, with an incidence of approximately 1 in 2.5 million live births. An estimated 50 craniopagus twins born around the world every year as of 2021, with only 15 twins surviving beyond the first 30 days of life. Relatively few craniopagus twins survive the perinatal period; approximately 40% of conjoined twins are stillborn and an additional 33% die within the immediate perinatal period, usually from organ abnormalities and failure. However, 25% of craniopagus twins survive and may be considered for a surgical separation; several ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Liver Surgery
The liver is a major organ only found in vertebrates which performs many essential biological functions such as detoxification of the organism, and the synthesis of proteins and biochemicals necessary for digestion and growth. In humans, it is located in the right upper quadrant of the abdomen, below the diaphragm. Its other roles in metabolism include the regulation of glycogen storage, decomposition of red blood cells, and the production of hormones. The liver is an accessory digestive organ that produces bile, an alkaline fluid containing cholesterol and bile acids, which helps the breakdown of fat. The gallbladder, a small pouch that sits just under the liver, stores bile produced by the liver which is later moved to the small intestine to complete digestion. The liver's highly specialized tissue, consisting mostly of hepatocytes, regulates a wide variety of high-volume biochemical reactions, including the synthesis and breakdown of small and complex molecule ...
