In radiology, the thumbprint sign, or thumbprinting, is a radiologic sign found on a radiograph that suggests the diagnosis of either epiglottitis or intestinal ischemia.. In a lateral C-spine radiograph, the sign is caused by a thickened free edge of the epiglottis, which causes it to appear more radiopaque than normal, resembling the distal thumb.
X-ray: uses X-rays to produce images of structures within the body; video link: Contrast media for X-rays: to provide a high contrast image of the details of the viscera under study; e.g. salts of heavy metals, gas like air, radio-opaque dyes, organic iodides, etc. Echocardiography machine: sonography of the heart is done here to know its ...
EOS is a medical imaging system designed to provide frontal and lateral radiography images, while limiting the X-ray dose absorbed by the patient in a sitting or standing position. The system relies on the high sensitivity of a detector ( multi-wire chamber ) invented by Georges Charpak , which earned him the 1992 Nobel prize .
Allied Communication Procedures is the set of manuals and supplements published by the Combined Communications Electronics Board that prescribe the methods and standards to be used while conducting visual, audible, radiotelegraph, and radiotelephone communications within NATO member nations.
Some recent advances rely on using simultaneously integrated physical phenomena, e.g. X-rays for both CT and angiography, combined CT/MRI and combined CT/PET. Discrete tomography and Geometric tomography , on the other hand, are research areas [ citation needed ] that deal with the reconstruction of objects that are discrete (such as crystals ...
The Merck Manuals (outside the U.S. and Canada: The MSD Manuals; Chinese: 默沙东诊疗手册; pinyin: Mòshādōng Zhěnliáo Shǒucè) are medical references published by the American pharmaceutical company Merck & Co. (known as MSD outside the United States and Canada), that cover a wide range of medical topics, including disorders, tests, diagnoses, and drugs.
For X-ray microtomography, powerful open source software is available, such as the ASTRA toolbox. [ 8 ] [ 9 ] The ASTRA Toolbox is a MATLAB and python toolbox of high-performance GPU primitives for 2D and 3D tomography, from 2009 to 2014 developed by iMinds-Vision Lab , University of Antwerp and since 2014 jointly developed by iMinds-VisionLab ...
The set up does not drastically differ for taking X-rays of cultural objects. The radiography of cultural property is the use of radiography to understand intrinsic details about objects. Most commonly this involves X-rays of paintings to reveal underdrawing , pentimenti alterations in the course of painting or by later restorers, and sometimes ...
