Radiography is an imaging technique using X-rays, gamma rays, or similar ionizing radiation and non-ionizing radiation to view the internal form of an object. Applications of radiography include medical and industrial radiography. Similar techniques are used in airport security,. To create an image in conventional radiography, a beam of X-rays is produced by an X-ray generator and it is projected towards the object. A certain amount of the X-rays or other radiation are absorbed by the object, dependent on the object's density and structural composition. The X-rays that pass through the object are captured behind the object by a detector. The generation of flat two-dimensional images by this technique is called projectional radiography. In computed tomography, an X-ray source and its associated detectors rotate around the subject, which itself moves through the conical X-ray beam produced. Any given point within the subject is crossed from many directions by many different beams at different times. Information regarding the attenuation of these beams is collated and subjected to computation to generate two-dimensional images on three planes which can be further processed to produce a three-dimensional image.
Fujifilm Holdings Corporation, trading as Fujifilm, or simply Fuji, is a Japanese multinational conglomerate headquartered in Tokyo, Japan, operating in the realms of photography, optics, office and medical electronics, biotechnology, and chemicals.
Mammography is the process of using low-energy X-rays to examine the human breast for diagnosis and screening. The goal of mammography is the early detection of breast cancer, typically through detection of characteristic masses or microcalcifications.
An X-ray machine is a device that uses X-rays for a variety of applications including medicine, X-ray fluorescence, electronic assembly inspection, and measurement of material thickness in manufacturing operations. In medical applications, X-ray machines are used by radiographers to acquire x-ray images of the internal structures of living organisms, and also in sterilization.
GE HealthCare Technologies, Inc., doing business as GE HealthCare, is an American multinational medical technology company headquartered in Chicago, Illinois. It was spun-off from General Electric on January 4, 2023, with GE retaining 13.5%. As of 2017, it is a manufacturer and distributor of diagnostic imaging agents and radiopharmaceuticals for imaging modalities used in medical imaging procedures. It offers dyes used in magnetic-resonance-imaging procedures; manufactures medical diagnostic equipment, including CT image machines; MRI, XRAY; Ultrasound; Cath Labs; Mammogram; Nuclear Medicine Cameras; and develops Health technology for medical imaging and information technologies, medical diagnostics, patient monitoring systems, disease research, drug discovery, and biopharmaceutical manufacturing. It was incorporated in 1994 and operates in more than 100 countries.
Digital radiography is a form of radiography that uses x-ray–sensitive plates to directly capture data during the patient examination, immediately transferring it to a computer system without the use of an intermediate cassette. Advantages include time efficiency through bypassing chemical processing and the ability to digitally transfer and enhance images. Also, less radiation can be used to produce an image of similar contrast to conventional radiography.
Dental radiographs, commonly known as X-rays, are radiographs used to diagnose hidden dental structures, malignant or benign masses, bone loss, and cavities.
Projectional radiography, also known as conventional radiography, is a form of radiography and medical imaging that produces two-dimensional images by X-ray radiation. The image acquisition is generally performed by radiographers, and the images are often examined by radiologists. Both the procedure and any resultant images are often simply called 'X-ray'. Plain radiography or roentgenography generally refers to projectional radiography. Plain radiography can also refer to radiography without a radiocontrast agent or radiography that generates single static images, as contrasted to fluoroscopy, which are technically also projectional.
SoftDent is a practice management software for dental offices. Originally developed by InfoSoft, based in White Marsh, MD. SoftDent was purchased by PracticeWorks which was then bought by Kodak. In May 2007, Kodak sold the dental PMS software business to Canadian company Onex, renamed Carestream, which currently markets and supports the SoftDent application. Carestream Dental split from Carestream Health in 2017 to be a stand-alone company. The application is not suited for very large offices or multi-location offices. The most recent version V18 was released in August 2019. CS SoftDent uses the C-tree database..
Tomosynthesis, also digital tomosynthesis (DTS), is a method for performing high-resolution limited-angle tomography at radiation dose levels comparable with projectional radiography. It has been studied for a variety of clinical applications, including vascular imaging, dental imaging, orthopedic imaging, mammographic imaging, musculoskeletal imaging, and chest imaging.
Photostimulated luminescence (PSL) is the release of stored energy within a phosphor by stimulation with visible light, to produce a luminescent signal. X-rays may induce such an energy storage. A plate based on this mechanism is called a photostimulable phosphor (PSP) plate and is one type of X-ray detector used in projectional radiography. Creating an image requires illuminating the plate twice: the first exposure, to the radiation of interest, "writes" the image, and a later, second illumination "reads" the image. The device to read such a plate is known as a phosphorimager.
Automatic Exposure Control (AEC) is an X-ray exposure termination device. A medical radiographic exposure is always initiated by a human operator but an AEC detector system may be used to terminate the exposure when a predetermined amount of radiation has been received. The intention of AEC is to provide consistent x-ray image exposure, whether to film, a digital detector or a CT scanner. AEC systems may also automatically set exposure factors such as the X-ray tube current and voltage in a CT.
Paul Suni is a Silicon Valley technologist, engineer, semiconductor device physicist and independent researcher. Since 1984, he has contributed to advancements in semiconductor electronics, photonics, digital imaging sensors and medical devices. In 2007, he dedicated himself to research concerning the scientific and philosophical foundations of technology and wellbeing.
The World Health Imaging, Telemedicine and Informatics Alliance (WHITIA) is a non-profit global health technology and social venture established in 2006 by affiliates of Northwestern University near Chicago, Illinois. WHITIA cultivates high-level strategic relationships with non-governmental organizations, imaging industry innovators and academic institutions in order to integrate and deliver meaningful, sustainable, diagnostic technology to underserved communities worldwide. WHITIA's vision is to facilitate the deployment of thousands of digital medical imaging systems worldwide, providing one billion people with access to diagnostic imaging. WHITIA was formerly known as the World Health Imaging Alliance (WHIA) until it formally expanded its scope in June 2009.
John Fitzallen Moore was an American physicist, the son of authors Virginia Moore and Louis Untermeyer. His last name was legally changed after his parents' divorce. His work in military electronics, communications, and spectroscopy culminated in medical electronics and x-ray products with the founding of the company Bio-Imaging Research.
Flat-panel detectors are a class of solid-state x-ray digital radiography devices similar in principle to the image sensors used in digital photography and video. They are used in both projectional radiography and as an alternative to x-ray image intensifiers (IIs) in fluoroscopy equipment.
A panoramic radiograph is a panoramic scanning dental X-ray of the upper and lower jaw. It shows a two-dimensional view of a half-circle from ear to ear. Panoramic radiography is a form of focal plane tomography; thus, images of multiple planes are taken to make up the composite panoramic image, where the maxilla and mandible are in the focal trough and the structures that are superficial and deep to the trough are blurred.
This is a list of infrared topics.
X-ray detectors are devices used to measure the flux, spatial distribution, spectrum, and/or other properties of X-rays.
