Theragenics® to Provide Sales and Marketing for C4 Imaging’s New Orion™ HDR MRI Markers


BUFORD, Ga.--(BUSINESS WIRE)-- Theragenics Corporation®, a medical device company serving the cancer treatment market, will provide sales and marketing for C4 Imaging’s novel, Orion Positive-Signal HDR MRI Lumen Marker. The marker is used prior to high dose rate (HDR) brachytherapy to accurately locate the position of the applicators that guide the placement of radioactive sources for the treatment of multiple cancers, including gynecological cancers. Using the superior imaging properties of MRI, the applicators can be positioned more precisely allowing for more accurate delivery of radiation to the tumor site while avoiding healthy surrounding organs and tissue. C4 Imaging recently received FDA 510(k) clearance for Orion.

Frank Tarallo, President and CEO of Theragenics commented, “C4 Imaging’s innovative HDR MRI marker should benefit patients by allowing more precise delivery of HDR brachytherapy, maximizing the therapeutic benefits of this treatment while minimizing potential side effects. We will utilize our expertise in brachytherapy and our established sales organization to effectively introduce and support the Orion.” Mr. Tarallo continued, “Theragenics has supported brachytherapy and the radiation oncology community for over 35 years. Leveraging our expertise and assets in our brachytherapy business, including our sales organization and our manufacturing capabilities in medical devices and nuclear medicine, is an important part of our strategy. We look forward to making this exciting new technology available to healthcare providers and patients.”

Andrew Bright, President and CEO of C4 Imaging commented, “Orion™, C4 Imaging’s Positive Signal HDR MRI Marker, which is based on the encapsulation of C4, our unique MRI agent, allows accurate positive-signal MRI treatment planning to be offered to cancer patients suitable for HDR treatment. C4 Imaging is delighted to partner with Theragenics, a longtime leader in serving the brachytherapy marketplace. We believe they will be a vital partner in making this new technology available to radiation oncologists and to patients.”
