In 2021 Hershey's unveiled the Whozeewhatzit bar [5] featuring the chocolate, cocoa crisps, crisped rice, and peanut butter ingredients of the Thingamajig bar from 2009. Hershey's held a naming contest for the new bar, with a $5,000 prize for the most creative name, along with a year's supply of the confection.
^ ASN.1 has X.681 (Information Object System), X.682 (Constraints), and X.683 (Parameterization) that allow for the precise specification of open types where the types of values can be identified by integers, by OIDs, etc. OIDs are a standard format for globally unique identifiers, as well as a standard notation ("absolute reference") for ...
Additionally, the Ottawa ankle rules indicate whether a foot X-ray series is required. It states that it is indicated if: There is any pain in the midfoot zone; and, Any one of the following: Bone tenderness at the base of the fifth metatarsal (for foot injuries), OR; Bone tenderness at the navicular bone (for foot injuries), OR
X-ray diffraction topography is one variant of X-ray imaging, making use of diffraction contrast rather than absorption contrast which is usually used in radiography and computed tomography (CT). Topography is exploited to a lesser extent with neutrons , and is the same concept as dark field imaging in an electron microscope .
Artificial X-ray sources Radiopharmaceuticals in radiopharmacology. Radioactive tracer; Brachytherapy; X-ray tube, a vacuum tube that produces X-rays when current flows through it; X-ray laser; X-ray generator, any of various devices using X-ray tubes, lasers, or radioisotopes; Synchrotron, which produces X-rays as synchrotron radiation ...
Electron beam computed tomography (EBCT) is a fifth generation computed tomography (CT) scanner in which the X-ray tube is not mechanically spun in order to rotate the source of X-ray photons. This different design was explicitly developed to better image heart structures that never stop moving, performing a complete cycle of movement with each ...
Low-dose high-resolution (1.25 mm) chest CT. HRCT is performed using a conventional CT scanner. However, imaging parameters are chosen so as to maximize spatial resolution: [1] a narrow slice width is used (usually 1–2 mm), a high spatial resolution image reconstruction algorithm is used, field of view is minimized, so as to minimize the size of each pixel, and other scan factors (e.g. focal ...
For imaging surfaces, the penetration of X-rays may be undesirable, in which case a glancing angle geometry may be used such as GISAXS. [2] A typical x-ray CCD is used to record the diffraction pattern. If the sample is rotated about an axis perpendicular to the beam a 3-Dimensional image may be reconstructed. [12]
