Radialis

Radialis is a private medical device company developing and commercializing organ-targeted positron emission tomography imaging systems. Its lead product, the Radialis PET Imager, is an FDA-cleared, small-field-of-view PET camera designed to generate high-resolution images of specific organs while using low radiotracer doses. The company positions the system as a complement to conventional whole-body PET/CT, with particular emphasis on breast imaging, treatment planning for primary solid tumors, and future low-dose molecular imaging applications. Radialis' technology originated from research at Lakehead University and the Thunder Bay Regional Health Research Institute, and the company manufactures medical devices in Thunder Bay, Ontario. In addition to commercial deployment, Radialis has supported clinical research including breast cancer imaging studies such as the bCOMBAT work and positron emission mammography studies.
