Magnetic resonance imaging (MRI) is a medical imaging technique used in radiology to form pictures of the anatomy and the physiological processes inside the body. MRI scanners use strong magnetic fields, magnetic field gradients, and radio waves to generate images of the organs in the body. MRI does not involve X-rays or the use of ionizing radiation, which distinguishes it from computed tomography (CT) and positron emission tomography (PET) scans. MRI is a medical application of nuclear magnetic resonance (NMR) which can also be used for imaging in other NMR applications, such as NMR spectroscopy.
Optical character recognition or optical character reader (OCR) is the electronic or mechanical conversion of images of typed, handwritten or printed text into machine-encoded text, whether from a scanned document, a photo of a document, a scene photo or from subtitle text superimposed on an image.
A microarray is a multiplex lab-on-a-chip. Its purpose is to simultaneously detect the expression of thousands of biological interactions. It is a two-dimensional array on a solid substrate—usually a glass slide or silicon thin-film cell—that assays (tests) large amounts of biological material using high-throughput screening miniaturized, multiplexed and parallel processing and detection methods. The concept and methodology of microarrays was first introduced and illustrated in antibody microarrays by Tse Wen Chang in 1983 in a scientific publication and a series of patents. The "gene chip" industry started to grow significantly after the 1995 Science Magazine article by the Ron Davis and Pat Brown labs at Stanford University. With the establishment of companies, such as Affymetrix, Agilent, Applied Microarrays, Arrayjet, Illumina, and others, the technology of DNA microarrays has become the most sophisticated and the most widely used, while the use of protein, peptide and carbohydrate microarrays is expanding.
The Allen Mouse and Human Brain Atlases are projects within the Allen Institute for Brain Science which seek to combine genomics with neuroanatomy by creating gene expression maps for the mouse and human brain. They were initiated in September 2003 with a $100 million donation from Paul G. Allen and the first atlas went public in September 2006. As of May 2012, seven brain atlases have been published: Mouse Brain Atlas, Human Brain Atlas, Developing Mouse Brain Atlas, Developing Human Brain Atlas, Mouse Connectivity Atlas, Non-Human Primate Atlas, and Mouse Spinal Cord Atlas. There are also three related projects with data banks: Glioblastoma, Mouse Diversity, and Sleep. It is the hope of the Allen Institute that their findings will help advance various fields of science, especially those surrounding the understanding of neurobiological diseases. The atlases are free and available for public use online.
The Shroud of Turin, also known as the Holy Shroud, is a length of linen cloth that bears a faint image of the front and back of a man. It has been venerated for centuries, especially by members of the Catholic Church, as the actual burial shroud used to wrap the body of Jesus of Nazareth after his crucifixion, and upon which Jesus's bodily image is miraculously imprinted. The human image on the shroud can be discerned more clearly in a black and white photographic negative than in its natural sepia color, an effect discovered in 1898 by Secondo Pia, who produced the first photographs of the shroud. This negative image is associated with a popular Catholic devotion to the Holy Face of Jesus.
Paul Ernest Debevec is a researcher in computer graphics at the University of Southern California's Institute for Creative Technologies. He is best known for his work in finding, capturing and synthesizing the bidirectional scattering distribution function utilizing the light stages his research team constructed to find and capture the reflectance field over the human face, high-dynamic-range imaging and image-based modeling and rendering.
An electron multiplier is a vacuum-tube structure that multiplies incident charges. In a process called secondary emission, a single electron can, when bombarded on secondary-emissive material, induce emission of roughly 1 to 3 electrons. If an electric potential is applied between this metal plate and yet another, the emitted electrons will accelerate to the next metal plate and induce secondary emission of still more electrons. This can be repeated a number of times, resulting in a large shower of electrons all collected by a metal anode, all having been triggered by just one.
The Houston Aeros were a professional ice hockey team in the World Hockey Association (WHA) from 1972 to 1978.
A photographic mosaic or photomosaic is a picture that has been divided into tiled sections, usually equal sized, each of which is replaced with another photograph that matches the target photo. When viewed at low magnifications, the individual pixels appear as the primary image, while close examination reveals that the image is in fact made up of many hundreds or thousands of smaller images. Most of the time they are a computer-created type of montage.
Dental radiographs, commonly known as X-rays, are radiographs used to diagnose hidden dental structures, malignant or benign masses, bone loss, and cavities.
Radius Recycling, previously known as Schnitzer Steel Industries, Inc., is a steel manufacturing and scrap metal recycling company headquartered in Portland, Oregon. Founded in 1906, the publicly traded company is a component Russell 2000 Index with approximately 3,500 employees. In 2023, the company adopted its current name and a new NASDAQ symbol of RDUS.
A film – also called a movie, motion picture, moving picture, picture, photoplay or (slang) flick – is a work of visual art that simulates experiences and otherwise communicates ideas, stories, perceptions, feelings, beauty, or atmosphere through the use of moving images. These images are generally accompanied by sound and, more rarely, other sensory stimulations. The word "cinema", short for cinematography, is often used to refer to filmmaking and the film industry, and the art form that is the result of it.

A variety of computer graphic techniques have been used to display video game content throughout the history of video games. The predominance of individual techniques have evolved over time, primarily due to hardware advances and restrictions such as the processing power of central or graphics processing units.
Positron emission tomography–magnetic resonance imaging (PET–MRI) is a hybrid imaging technology that incorporates magnetic resonance imaging (MRI) soft tissue morphological imaging and positron emission tomography (PET) functional imaging.
Harold J. Schnitzer was an American businessman, civic leader, and philanthropist. Schnitzer is best remembered for having made over $80 million in charitable gifts over the course of his lifetime, including the establishment of the Harold Schnitzer Family Program in Judaic Studies at Portland State University in Portland, Oregon and at the University of Oregon.
The visual arts are art forms such as painting, drawing, printmaking, sculpture, ceramics, photography, video, filmmaking, comics, design, crafts, and architecture. Many artistic disciplines, such as performing arts, conceptual art, and textile arts, also involve aspects of the visual arts as well as arts of other types. Also included within the visual arts are the applied arts, such as industrial design, graphic design, fashion design, interior design, and decorative art.
Arlene Schnitzer was an American arts patron and philanthropist. She was the founder and director of the Fountain Gallery, established in Portland to showcase artists in the Pacific Northwest. She is the namesake of the Arlene Schnitzer Concert Hall, a performing arts center in Portland, Oregon.
An optical head-mounted display (OHMD) is a wearable device that has the capability of reflecting projected images as well as allowing the user to see through it. In some cases, this may qualify as augmented reality (AR) technology. OHMD technology has existed since 1997 in various forms, but despite a number of attempts from industry, has yet to have had major commercial success.
X-ray computed tomography operates by using an X-ray generator that rotates around the object; X-ray detectors are positioned on the opposite side of the circle from the X-ray source.
