I am opening a new practice and just researched some different options for digital x-rays. I chose to purchase the A2D2 system from one of their dealers, FOZ Networks. I looked at CR and DR systems, and DR was the obvious choice for me because of the difference in processing time. DR does not use cassettes (which need processing), so the patient throughput is much faster. They do not charge any fees for annual software maintenace or support, which could add up to thousands per year with other systems. Image quality is excellent and the software tools are geared towards podiatry.
