Augmented reality (AR) is the virtual object which is combination of 3D real environment in the real time. It is more interactive either with graphics or audio enhancing from what we can sense such smell, hear, see or feel it. In other words, it is duplicate the environment around the world in computer. There are applications in various areas in augmented reality and one of them is medical visualization more domain for augmented reality. The topic that discussed is augmented reality application in computer aided surgery and medicine. In research article (Tobias Sielhorst, Marco Feuerstein & Nassir Navab, 2008) medical augmented reality takes it motivation from the need of visualizing medical data and the patient within the same physical space. The reason for chose this topic because it is because this application more advance and the technologies always bring new visualization and interaction using augmented reality in 3D in surgery performing requirements. So, discussing these topics actually need many evaluations to perceive the result to the area of surgery and medicine in medical performance.
Why augmented reality application in computer aided surgery and medicine an interesting topic? Is the integration between real and virtual object really gives benefits for the surgery field? Surgery performs most of their works are deal with visualization and imaging during operation for necessary image for example using computerized tomography(CT). CT scans using 3D image to visualize inside of an object. Inside the CT scans we can see layers of tissues inside our organ and transmitted it to displays part of our body on the CT screen. These function actually really useful for performing surgery because it can help reducing the trauma of...

The Da Vinci Surgical System is a large purpose-built robot controlled by a surgeon that performs minimally invasive surgical procedures on patients. The system incorporates an ergonomically designed surgeon's console, a patient-side module with four interactive robotic arms, each with interchangeable surgical instruments and a 3-dimensional endoscopic vision system. Powered by high-tech supercomputers, the surgeon's hand movements are scaled, filtered and then converted into precise movements of the surgical attachments. The designers of the system are a team of doctors, engineers and biomedical engineers at a company called Intuitive Surgical.

If this was a perfect world, the moment a person underwent a surgery there would be no risk of having after effects of a major surgery. The doctors would be able to diagnose, treat and cure patients without causing any harmful side effects but reality is the total opposite of this. There is something that is helping to improve the perfect world that we reside upon in the medical field with Medical Imaging this fact has been improving. The use of medical imaging has provided the opportunity to the doctors to see inside a patient without having to cut them open. Medical imaging is the visualization of body parts, tissues, or organs, for use in clinical diagnosis, treatment and disease monitoring. It has also helped on many other fields for example it the field of neurobiology and human behavior. Imaging techniques encompass the fields of radiology, nuclear medicine and optical imaging and image-guided intervention, furthermore medical imaging is justified also to follow the course of a disease already diagnosed and/or treated.
...ases strain and likelihood of error which results in an increase in the time taken to perform the procedure. Computer assisted surgery uses computers for guiding and performing surgical intrusions in addition to pre-surgical planning. Robotic surgery or robotically assisted surgery overcomes the limitations of traditional Human-Machine Interfaces and enhance the abilities of surgeons during open surgeries. Moreover, there are numerous training simulators available to surgeons for practice and learning purposes.

Augmented Reality (AR) is a real time direct or indirect view of the physical real world that is enhanced or augmented with computer generated information. AR is both interactive and registered in 3D, combining real and virtual objects. AR enhances a user’s perception of the real world and the way they interact with it. The augmented Reality’s main purpose is simplifying the user’s life, by bringing virtual information to their immediate surroundings through an indirect view of the real-world environment. Although augmented reality is like Virtual reality (VR), AR is an enhanced view of the real world, where VR is a pure virtual environment.
To begin with, how has technology changed the field of radiology? Since the discovery of X-radiation there has been a need and desire for studying the human body and the diseases without actually any intervention. Over the past fifty years there has been a revolution in the field of radiology affecting medicine profoundly. “The ability to produce computers powerful enough to reconstruct accurate body images, yet small enough to fit comfortably in the radiology department, has been the major key to this progress”(Gerson 66). The core of radiology’s vast development consists of four diagnostic techniques: computed tomography (CT), digital subtraction angiography (DSA), ultrasonography, and magnetic resonance imaging (MRI). These methods of diagnostic imaging provide accurate information that was not seen before. Amid this information advancement, radiologists have broadened their role of diagnostician. Gerson writes, “With the advent of computer-enhanced imagery and new interventional techniques, these physicians are able to take an active part in performing therapeutic procedures”(66). A radiology breakthrough in 1972 was computed tomography discovered by Godfrey Hounsfield and Allan Cormack. Unlike standard radiography, computed tomography would spin the X-ray tube 360 degrees and inversely another 360 degrees while the patient ta...
Augmented reality is a medium that gives us the ability to experience the combination of reality and superimposed or virtual objects
The story of augmented reality goes back as far as the early 1900’s when L. Frank Baum wrote the “novel The Master Key. Printed in 1901, the book mentions a “character marker” set of electronic spectacles that when you view someone through them would show a letter on that person’s forehead regarding their character.” However, the first invention to use some type of augmented reality would not come along till 1968 and Ivan E. Sutherland and his head mounted three dimensional display. “The fundamental idea behind the three-dimensional display is to present the user with a perspective image which changes as he moves.” This would allow for an illusion of 3D on a 2D plane. This however, wasn’t true augmented reality; yes this augmented what you see on a screen and gave an illusion of 3 dimensions, but it does not overlay actual reality with com...
Since the beginning of time, human beings have been in search of ways to advance life as we know it. Every single day, somewhere in the world, technology is being transformed and an exciting new piece is birthed into society. Perhaps, one of the most influential advances is in our ever evolving medical profession. Thus, as technology continues to change the world as we know it, it is sweeping the medical field right along with it. Surgical procedures are being drastically improved with the use of robotic technology called da Vinci.
Images of human anatomy have been around for more than 500 years now. From the sketches created by Leonardo da Vinci, to the modern day Computed Tomography (CT) or Magnetic Resonance Imaging (MRI) scan, images have played a great role in medicine. Evolution in medical imaging brought together people from various disciplines such as Biology, Physics, Chemistry and Mathematics, a collaboration which has further contributed to healthcare as a whole. Modern day imaging improves medical workflows by facilitating a non-invasive insight into human body, accurate and timely diagnostics, and persistence of an analysis.
Augmented Reality (AR)/Virtual Reality (VR) . AR is generally used to refer to a live, real world environment, augmented with additional video and/or data. Since the success of Pokémon Go, an AR game where computer-generated characters appear on a mobile device screen as if they’re in the real world, exploded with over 100 million downloads, Hollywood has been exploring the technology's potential for storytelling. But AR could soon move beyond a phone, since headsets, glasses and even contact lenses with AR capabilities are in development. Many are exploring the potential to offer new types of immersive, interactive stories or games -- imagine taking elements of the Star Wars universe
“Augmented Reality is a technology, a field of research, a vision of future computing, an emerging commercial industry and a new medium for creative expression.” (Becker, 2010)
The science of Virtual Reality has stated its presence in the media and now it is turning the eyes to see the new generation of games and 3D application.
