Franklin & Seidelmann Subspecialty Radiology, a Cleveland startup focused on remote analysis of X-ray and other medical images, raised $25 million from Oak Investment Partners, a Westport, Conn., venture-capital firm.

Founded in 2001, Franklin & Seidelmann provides outsourced reading of X-rays, MRI scans and other medical images -- services known generally as "teleradiology" -- for a variety of medical specialties via a network of 30 subspecialty radiologists. The company said the proceeds will allow it to accelerate its spending on "technology infrastructure."
