To help me understand the science behind some of these issues, I spoke with Doug Yoon, DDS, the founder of XDR Radiography. Dr. Yoon has more than 20 years of technical experience in the aerospace industry and more than 10 years of experience in digital radiography in both industry and as a faculty researcher in oral radiology at the UCLA School of Dentistry. There, he helped develop the first automated digital caries recognition system.
Dr. Yoon explained that there are two different types of resolution and that they measure quite different things. Spatial resolution and contrast resolution are often confused.
