What is spatial resolution, and how do digital X-ray detectors compare?
Spatial resolution is the size of the smallest detail that can be seen with an imaging system, and is primarily limited by the size of the pixels in the digital X-ray detector. Envision’s Mini CMOS digital X-ray detectors have a pixel size of 39 microns (0.0015″), producing the highest spatial resolution currently available in the digital x-ray industry, without geometric magnification. With geometric magnification (using a micro-focus x-ray source) spatial resolution of a few microns can be achieved. EnvisionScan CMOS line array detectors have a pixel size of 80 microns (0.0031″), producing approximately 30% better spatial resolution than amorphous silicon or selenium panels, without geometric magnification. With geometric magnification (using a micro-focus x-ray source) spatial resolution of a few microns can be achieved. For comparison: the best linear diode arrays (LDA s) have a spatial resolution of 250 microns, the best CCD-based imagers have a spatial resolution of 160 microns,
