Document Summary

Now more complex different monitors with their own contrast & spatial resolution. Monitors serve to provide the user w/ a visual display. Image formation store in matrix array which is composed of spatially encoded numerical values. Users can access info stored in computer"s memory system and make meaningful/useful inferences based on that info. Primary monitor monitor radiologist looks off of. Mammo monitor even more expensive and specialized. Need to be calibrated in way to allow for full and perceptible display or digitized info. Assist in this effort and test monitor"s ability to meet performance req. , various test tools have been developed. If monitor isn"t optimized everything else is waste images can not look good w/ poor monitor. Smpte - society of motion picture and television engineers: came up with tool, newer design developed by aapm, smpte task group 18. Lot of squares that allow us to see spatial resolution patterns.
