C-Arm Comparison: ZIEHM VISION RFD vs Oscar 15 FD

Here’s comparison review of Ziehm Vision RFD which is regarded as one of Ziehm’s top model and Genoray’s Oscar 15 FD.  Both system features Flat Detector panel instead of II and comes with lots of advanced capabilities and close competitors.  Let’s see how they measure up on key specs!

 
Brand & ModelZIEHM VISION RFDGenoray Oscar 15 FD
X-ray Generation25kW Rotating Anode15kW Rotating Anode
X-ray Cooling Rate85,000 HU/min100,000 HU/min
kV Range40~ 120kV40-120kV
Pulse Rate1 ~ 25 pps1 ~ 30 pps

X-ray Category: Who Wins?
Too Close to Call.  Ziehm has higher kW rating but same kV limit and Oscar 15 offer 30pps pulse… this would be a tie!

DetectorFlat Detector 20 x 20cm or 30 x 30cm (11.81 inches)Flat Detector 26 x 26cm (10.24 inches)
Resolution (more pixels the better)1024 x 1024 pixels2,600 x 2,560 pixels
Pixel pitch (smaller the better)not listed100 u

Detector Category: Who Wins?
Depends.  Vision RFD has slightly bigger panel but Oscar 15 has better resolution, which typically means better image quality.

Hi. I think you are wrong comparing the x-ray cooling rate. 85.000 HU/min are the anode heat disipation rate, which is the data given by the manufacturer of the x-ray tube in laboratories conditions whitout attached dissipation systems, so clinically is not rellevant . You should compare the system heat disipation or dissipation rate in continuous clinical perfomance, which takes into account the cooling systems and are more clinically relevant. From this point of view, it seems that Ziehm has no competitors. Ziehm RFD systems could be aSi (194 um) or CMOS (100 um). So, resolution is 1,536 x 1,536… Read more »
