Cinematic Rendering
In medical diagnostics, cinematic rendering is an image processing technique applied to create three-dimensional, photorealistic images of cross-sectional data, such as computed-tomography, or magnetic resonance imaging (MRI)/ Cinematic rendering is an alternative to the volume rendering, the name was inspired by the modern computer animation techniques that allow studios, like Pixar, to create realistically looking objects. The steps used to produce the cinematic rendering are similar to the ones for the volume rendering: * the magnitude (gray) value of each voxel (3-dimensional pixel) produced during the scan is mapped into the color and opacity pair based on what structures need to be highlighted or hidden; * ray casting used for volume rendering, where each pixel in the 2D image is formed by a single ray of light, is replaced by path tracing with a global illumination model that integrates over all the illuminance arriving to every single point on the surface of an object. ...

Volume Rendering And Cinematic Rendering Of A Whole-body CT Scan
Volume is a Measure (mathematics), measure of Region (mathematics), regions in three-dimensional space. It is often quantified numerically using SI derived units (such as the cubic metre and litre) or by various imperial units, imperial or United States customary units, US customary units (such as the gallon, quart, cubic inch). The definition of length and height (cubed) is interrelated with volume. The volume of a container is generally understood to be the capacity of the container; i.e., the amount of fluid (gas or liquid) that the container could hold, rather than the amount of space the container itself displaces. By metonymy, the term "volume" sometimes is used to refer to the corresponding region (e.g., bounding volume). In ancient times, volume was measured using similar-shaped natural containers. Later on, standardized containers were used. Some simple Three dimensional, three-dimensional shapes can have their volume easily calculated using arithmetic formulas. Volume ...

Photorealistic
Photorealism is a genre of art that encompasses painting, drawing and other graphic media, in which an artist studies a photograph and then attempts to reproduce the image as realistically as possible in another medium. Although the term can be used broadly to describe artworks in many different media, it is also used to refer to a specific art movement of American painters that began in the late 1960s and early 1970s. History Origins As a full-fledged art movement, Photorealism evolved from Pop ArtLindey (1980), pp. 27–33.Meisel and Chase (2002), pp. 14–15.

Computer Graphics Algorithms
A computer is a machine that can be programmed to automatically carry out sequences of arithmetic or logical operations (''computation''). Modern digital electronic computers can perform generic sets of operations known as ''programs'', which enable computers to perform a wide range of tasks. The term computer system may refer to a nominally complete computer that includes the hardware, operating system, software, and peripheral equipment needed and used for full operation; or to a group of computers that are linked and function together, such as a computer network or computer cluster. A broad range of industrial and consumer products use computers as control systems, including simple special-purpose devices like microwave ovens and remote controls, and factory devices like industrial robots. Computers are at the core of general-purpose devices such as personal computers and mobile devices such as smartphones. Computers power the Internet, which links billions of computer ...

Medical Imaging
Medical imaging is the technique and process of imaging the interior of a body for clinical analysis and medical intervention, as well as visual representation of the function of some organs or tissues (physiology). Medical imaging seeks to reveal internal structures hidden by the skin and bones, as well as to diagnose and treat disease. Medical imaging also establishes a database of normal anatomy and physiology to make it possible to identify abnormalities. Although imaging of removed organ (anatomy), organs and Tissue (biology), tissues can be performed for medical reasons, such procedures are usually considered part of pathology instead of medical imaging. Measurement and recording techniques that are not primarily designed to produce images, such as electroencephalography (EEG), magnetoencephalography (MEG), electrocardiography (ECG), and others, represent other technologies that produce data susceptible to representation as a parameter graph versus time or maps that contain ...

3D Computer Graphics
3D computer graphics, sometimes called Computer-generated imagery, CGI, 3D-CGI or three-dimensional Computer-generated imagery, computer graphics, are graphics that use a three-dimensional representation of geometric data (often Cartesian coordinate system#Cartesian coordinates in three dimensions, Cartesian) that is stored in the computer for the purposes of performing calculations and rendering digital images, usually 2D images but sometimes 3D images. The resulting images may be stored for viewing later (possibly as an Computer animation, animation) or displayed in Real-time computer graphics, real time. 3D computer graphics, contrary to what the name suggests, are most often displayed on two-dimensional displays. Unlike 3D film and similar techniques, the result is two-dimensional, without visual depth perception, depth. More often, 3D graphics are being displayed on 3D displays, like in virtual reality systems. 3D graphics stand in contrast to 2D computer graphics which t ...

3D Rendering
3D rendering is the 3D computer graphics process of converting 3D models into 2D images on a computer. 3D renders may include photorealistic effects or non-photorealistic styles. Rendering methods Rendering is the final process of creating the actual 2D image or animation from the prepared scene. This can be compared to taking a photo or filming the scene after the setup is finished in real life. Several different, and often specialized, rendering methods have been developed. These range from the distinctly non-realistic wireframe rendering through polygon-based rendering, to more advanced techniques such as: scanline rendering, ray tracing, or radiosity. Rendering may take from fractions of a second to days for a single image/frame. In general, different methods are better suited for either photorealistic rendering, or real-time rendering. Real-time Rendering for interactive media, such as games and simulations, is calculated and displayed in real time, at rates ...

American Journal Of Roentgenology
The American Journal of Roentgenology (''AJR'') is a monthly peer-reviewed journal that covers topics in radiology. It is published by the American Roentgen Ray Society (ARRS) and is based in Leesburg, VA. The current editor-in-chief (August 2020) is Andrew B. Rosenkrantz. History The publication has undergone several changes throughout its history. The initial publication in 1906 was entitled the ''American Quarterly of Roentgenology'', and was officially associated with the ARRS in 1909. In 1913, journal was renamed the ''American Journal of Roentgenology'', and publication frequency was increased to a monthly basis under editor Preston M. Hickey. Hickey would remain editor-in-chief for approximately 10 years, and became a pioneering voice for evolution of radiologic education and reporting. With the advent of radiation therapy and nuclear medicine under the auspices of radiology, there was a period from 1920 to 1970s during which the ARRS began publishing articles on topic ...
