Continuous developments in digital imaging technology have contributed to the vital role held today by digital X-ray imaging in the cardiac catheterization laboratory. Foremost among these developments is the replacement of cine film with digital data equivalents as the procedure record. Other improvements include software innovations and processing algorithms, along with new types of hardware capable of delivering required functionality more rapidly. A significant recent development is that of the flat-panel X-ray detector as a replacement for the image intensifier, which has served the needs of the cardiac catheterization laboratory for nearly 5 decades. Clinical users must evaluate the respective technologies and determine whether one or the other meets the needs of their own laboratories. In this review, the two competing detector technologies are reviewed and a summary of general advantages and disadvantages of each is provided. A qualitative description is provided of parameters that can be used to assess quantitatively the performance of detectors and imaging systems. Using such objective measurements, together with standard techniques for evaluating imaging systems, angiographers and managers can better arrive at informed decisions for their own situation.
