C4 Imaging LLC

C4 Imaging develops innovative medical devices that enable clinicians to personalize patient care through accurate image-guided procedures. The company’s core proprietary technology, C4, is a unique magnetic resonance imaging (MRI) agent that has been encapsulated within a variety of implantable, biocompatible shells. C4 Imaging’s first two products are focused on enhancing radiation treatment with brachytherapy. The Sirius MRI Marker is used to facilitate seed localization during the treatment of prostate cancer with low dose rate (LDR) radioactive seeds. Sirius allows physicians to accurately locate seeds within the complicated anatomy of the prostate and the surrounding critical structures, utilizing a single post-implant MRI procedure.
