CONCLUSION
Digital imaging systems are often referred to as imaging chains in which the diagnostic utility of the system is limited by its weakest link. For this reason, it is important not to limit
an imaging system with low-quality monitors. However, a good-quality monitor will not compensate for poor-quality radiographs
or a low-quality digital radiography system.
Monitor purchasing decisions should depend on the requirements of the practice and the uses of the workstation. Ideally, all
clinics using digital radiography would be equipped with high-quality, high-resolution grayscale monitors. At a minimum, a
medical-grade monitor is recommended for the primary workstation, but a high-quality consumer-grade monitor can be considered
for other applications.20
