What is a primary advantage of digital fluoroscopy over conventional fluoroscopy?

A primary advantage of digital fluoroscopy over conventional fluoroscopy is the ability to perform image subtraction. This technique allows for the enhancement of visualizing blood vessels and other structures by removing overlapping structures from the image. In digital fluoroscopy, images can be manipulated and enhanced using algorithms that can selectively remove certain components of an image. This capability improves the clarity and diagnostic value of the images, particularly in applications such as angiography.

While dynamic range, image acquisition rate, and progressive mode are relevant features of digital imaging, they do not provide the specific benefit of selectively enhancing certain features while eliminating others like image subtraction does. Thus, the ability to perform image subtraction represents a significant advancement that improves diagnostic accuracy and visualization in various medical imaging procedures.
