C-arm sector features new models, improvements in technology

In January, Whale Imaging received FDA clearance for its G-Arm B6 Duo. The improvements over the previous model, the GXi-2, which was introduced in 2015, include compatibility with the Jackson spine table and 45-degree axial tilt, or head-to-toe movement, says Philip Posa, vice president of sales for Whale Imaging. The major difference between the company’s G-arm and a conventional C-arm is that a C-arm moves in one direction. The company’s technology allows for both the AP and lateral images to be captured at once. This has the potential to reduce dose and procedure time and minimize the risk of infection, Posa says.

“In order to get an AP and lateral view, you have to move the C-arm,” Posa says. “You’re not moving a G-arm from AP to lateral and back and forth and disrupting [the] sterile field.” The system offers panoramic view and stitching of the spine, allowing surgeons to count vertebrae, Posa says. “A surgeon wants to make sure they’re working on the right spot,” Posa says. “They’re always counting. This allows for easy counting to make sure you’re in the right area. In a very scoliotic spine, it allows for better understanding of the procedure.” The company debuted the G-Arm B6 Duo at the American Society of Spine Radiology (ASSR) meeting in February.

At last year’s RSNA, Ziehm Imaging presented its Ziehm Solo FD and the Ziehm Vision RFD, both mobile C-arms with CMOS flat-panel detectors, what the company says are the first full-size C-arms equipped with the CMOS technology. The Ziehm Solo FD provides optimal soft tissue and bone contrast especially in orthopedic, trauma and pain management procedures, according to the company. The Ziehm Vision RFD, which comes with a 25-kilowatt generator for vascular procedures, has been commercially available with CMOS technology since last month.

To broaden the CMOS product portfolio, Ziehm introduced a new version of its Ziehm Vision FD, which now features the new detector technology. The company also debuted its Ziehm NaviPort 3D interface for image-guided navigation, which the company says improves reliability and precision during surgical procedures, and the Ziehm Vision RFD Hybrid Edition, which the company says is the first fully motorized mobile C-arm, which can be used as an alternative to fixed systems for cardiovascular procedures. “I am convinced that our latest flat-panel detector generation further strengthens Ziehm Imaging’s technological leadership by combining outstanding image quality and efficient workflow,” says Klaus Hörndler, chief executive officer of Ziehm Imaging. “Overall, our CMOS flat-panel detector is an excellent package, offering more possibilities and benefits for the clinician while keeping dose levels minimized.”
