This weeks topic on digital radiography is detector latitude. Detector latitude is the ability of a receptor to capture a range of x ray exposures. The term used to describe this is magnitude. Analog film has a large range of magnitudes from 0.5 to 4, however, only under bright illumination […]
This weeks topic on digital radiography is spatial resolution. Spatial resolution is the capacity for distinguishing fine detail in an image. The term used to identify this is line pairs per millimeter (lp/mm). The higher the spatial resolution, the greater the capacity for distinguishing fine detail. An average observer is […]
This weeks topic on digital radiography is contrast resolution. Contrast resolution is the ability to distinguish gray levels on an image. The term used to identify how many gray levels that can be identified is bits. When any number is in front of bits, such as 8 bits or 14 […]
