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 & Model | ZIEHM VISION RFD | Genoray Oscar 15 FD |
| X-ray Generation | 25kW Rotating Anode | 15kW Rotating Anode |
| X-ray Cooling Rate | 85,000 HU/min | 100,000 HU/min |
| kV Range | 40~ 120kV | 40-120kV |
| Pulse Rate | 1 ~ 25 pps | 1 ~ 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!
| Detector | Flat 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 pixels | 2,600 x 2,560 pixels |
| Pixel pitch (smaller the better) | not listed | 100 u |
Detector Category: Who Wins?
Depends. Vision RFD has slightly bigger panel but Oscar 15 has better resolution, which typically means better image quality.
| Free Space | 840mm / 33.10″ | 800mm / 31.49″ |
| Depth of Arc | 680mm / 26.77″ | 730mm / 29″ |
| Orbital Rotation | 90/75 (overcast) degrees | 90/60 (overcast) degrees |
| Panning Motion | +-12.5 degrees |
Physical Spec Category: Who Wins?
Vision RFD, it has bigger opening and more orbital rotation.
| Advanced Features | 3D, motorized option available | Network Capable (Windows), Remote Control Diagnostic, Virtual Collimator, Adjustable Low Dose Mode |
| Storage | 100,000 images | 4~5 Million images |
| Output | DVD, USB, Thermal Printer, DICOM | DVD, USB (JPG or BMP or DICOM), Thermals or HP printer, DICOM |
| Warranty & Support | 12 Months | 5 Year Full Parts Warranty + 1 Year Labor Warranty LIFETIME Phone & Remote Control Support! |
Which do you think is a winner? Which would you get? Tell me your thoughts below!
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 »
You’re correct that I’m using lab numbers provided by the manufacturer. In fact, in my opinion, cooling rate doesn’t really matter for most equipment that are modern as none of them have the heating issue older systems did… But I include that number because customers ask for them… if you ask me whether it’s 85K or 100K or etc, make no difference unless it’s done real life testing…
