Latitude X Ray Definition

Exposure latitude is the extent to which a light sensitive material can be overexposed or underexposed and still achieve an acceptable result.

Latitude x ray definition. Unless you make the recording data bucket significantly bigger better codec and more bits 10 bit 12 bit etc you can t put more data dynamic range or stops into that bucket without it overflowing or without squashing it. Geometric factors include the size of the area of origin of the radiation the source to detector film distance the specimen to detector film. So bigger dynamic range does not mean greater latitude in fact in many cases it means less latitude. How to use latitude in a sentence.

Latitude is an angle which ranges from 0 at the equator to 90 at the poles. Optical microlithography or photography. As mentioned previously radiographic definition is the abruptness of change from one density to another. Latitude is used together with longitude to specify the precise location of features on the surface of the earth.

Radiographic contrast is the density difference between neighboring regions on a plain radiograph. High radiographic contrast is observed in radiographs where density differences are notably distinguished black to white. On its own the term latitude should be taken to be the geodetic latitude as. Lines of constant latitude or parallels run east west as circles parallel to the equator.

La latitude est une coordonnée géographique représentée par une valeur angulaire expression de la position d un point sur terre ou sur une autre planète au nord ou au sud de l équateur qui est le plan de référence. This measure is used for digital and analogue processes e g. Geometric factors of the equipment and the radiographic setup and film and screen factors both have an effect on definition. Latitude definition is angular distance from some specified circle or plane of reference.

Narrow exposure latitude very easy ot over or underexpose film needs to be processed in a dark room automatic processors are costly to maintain x ray films are expensive image storage takes lots of space no post processing capabilities. Elle varie entre la valeur 0 à l équateur et 90 aux pôles n 1 la latitude est utilisée en combinaison avec la longitude. La latitude est une mesure angulaire. In geography latitude is a geographic coordinate that specifies the north south position of a point on the earth s surface.
