C4 Imaging develops medical devices that enable clinicians to personalize patient treatment through accurate image-guided procedures. The Company’s core proprietary technology, C4, is a unique magnetic resonance imaging agent that has been encapsulated within an implantable, biocompatible shell. C4 Imaging's goal is to allow post-implant seed localization to be performed with MRI alone, eliminating the use of computed tomography in assessment of prostate brachytherapy.
