The Philips Allura FD20 and FD10 may be similar in appearance at a glance, but they are very different machines in a number of ways. The main difference between them is the work they are used for. The FD10 is primarily a cardiac system. It does have some options that may allow for light peripheral work, but cardiac studies are what it was designed for. The FD20 was designed, when equipped with the appropriate software, to handle a much broader spectrum of applications, including (but not limited to): angio, cardiac, neuro, and vascular.
To keep you better informed about where each of these systems shines, we've compiled a short list of the most relevant similarities and differences between the FD10 and the FD20 below.
