Samsung touts commitment to lowering dose across digital X-ray portfolio

Samsung’s GC85A with S-Vue
Samsung announced last Tuesday that it’s committed to lowering radiation dose exposure across its entire digital X-ray portfolio.

One of the ways the company has demonstrated that is with the introduction of its GC85A fully-digital X-ray system.

That system delivers the same image quality as the predicate device, but with half the radiation exposure. It’s able to do that because of its image post-processing engine S-Vue 3.02, which received FDA clearance last November.

New Fully Configured 80-slice CT in 2 weeks with Software Upgrades for Life

For those who need to move fast and expand clinical capabilities -- and would love new equipment -- the uCT 550 Advance offers a new fully configured 80-slice CT in up to 2 weeks with routine maintenance and parts and Software Upgrades for Life™ included.

“The new technology features a low dose post-processing chain which is a multi-resolution-based de-noising method for preserving the structural and anatomy information,” Philip Sullivan, president and CEO of NeuroLogica, a subsidiary of Samsung, told HCB News. “The resulting performance will allow our customers to lower their protocols to achieve the same level of diagnosable images.”

Patients who undergo a chest X-ray with GC85A are subject to eight microsieverts of radiation, which is equivalent to the average dose exposure during a three-hour flight.

Dr. Hetal Patel, chief of radiology at ARMC-Cone Health in North Carolina, recently participated in Samung’s Low Dose Study, in which he evaluated ten X-rays and found that the overall image quality was “excellent.”

“The reduced-dose X-ray was either of comparable quality or better quality, and I would advocate for all chest X-rays to be done using this methodology,” he said in a statement.

In March, Samsung received Low Dose clearance from the South Korea Ministry of Food & Drug Safety and CE mark for applying dose reduction technology in its other X-ray models.

The company is also focused on lowering CT dose. It has technology and programs in place for XR-29 compliance, automatic exposure control, beam efficiency and low noise data acquisition.

Samsung also uses special image reconstruction kernels and the adaptive noise reduction to provide low-dose lung screening, ensures its mobile CTs are internally lead shielded, and deploys advance post-processing solutions to reduce the need for repeat scanning.
