Scintillator
A substance that emits light when exposed to ionizing radiation. Cesium panels are slightly more expensive but significantly more reliable. Thanks to their higher sensitivity, they provide the best image quality at the lowest dose.
Pixel Pitch
Pixel pitch. The distance in mm from the center of a pixel to the center of an adjacent pixel of the same color. The smaller the pixel pitch, the sharper the displayed images. The optimal pitch in radiography is 100-150 microns.
A / D Convertion
Converting an analog signal to a digital signal. More bits mean more shades of gray can be represented on the screen. The human eye can distinguish over 720 shades of gray, which corresponds to approximately 9/10 bits.
MTF
Modulation Transfer Function. The ability of a device to transfer varying levels of detail from an object to an image. MTF is the best measure of true image sharpness, accounting for blur and contrast.
Spatial Resolution
Spatial resolution. The size of the smallest object that can be recognized by the detector. Resolution can be measured in line pairs per millimeter (Lp/mm). The higher the Lp/mm value, the more precise the image.
Spatial Resolution
A measure that compares the level of the useful signal to the level of background noise. A lower signal-to-noise ratio typically results in a grainy appearance of images. To achieve a higher SNR, the number of photons (mAs) must be increased or their energy (kV) must be decreased.
