The Harvard Laboratory for Computer Graphics and Spatial Analysis (1965 to 1991) pioneered early cartographic and architectural computer applications that led to integrated geographic information systems (GIS). [1] Some of the Laboratory's influential programs included SYMAP, SYMVU, GRID, CALFORM, and POLYVRT.
Depending on how much these pigments absorb X-rays affects how clear or opaque they will appear in the radiograph, this is known as X-ray fluorescence. [ 4 ] [ 10 ] Lead white , for example, will absorb more rays and appear much more opaque on an X-radiograph than carbon black , which will allow most of the X-rays to pass through resulting in a ...
Chest photofluorography, or abreugraphy (better known as mass miniature radiography in the UK and miniature chest radiograph in the US), is a photofluorography technique for mass screening for tuberculosis using a miniature (50 to 100 mm) photograph of the screen of an X-ray fluoroscopy of the thorax, first developed in 1936.
For most simple Harvard citations the templates {}, {}, and {} are easier to use. The template name "Harvard citations" can be abbreviated as "harvs". Note that the use (or even non-use) of these templates is an element of citation "style", and adding or removing them in articles with an established style should be consistent with that style.
Spectral imaging is an umbrella term for energy-resolved X-ray imaging in medicine. [1] The technique makes use of the energy dependence of X-ray attenuation to either increase the contrast-to-noise ratio, or to provide quantitative image data and reduce image artefacts by so-called material decomposition.
After you write your article, be sure to add the project template, {{WPWS}}, to the talk page. If there is a template on the article page regarding work that needs to be done on the article - if you successfully complete the task of fixing the problem, be bold and remove the template.
Staging information which is obtained prior to surgery, for example by x-rays and endoscopic ultrasound, is called clinical staging; staging by surgery is known as pathological staging. Clinical staging is done by a combination of imaging and sampling (biopsies), or stated differently, non-invasive (radiological) and invasive (biopsy) methods.
