CAD solutions provider iCAD Inc., based in Nashua, N.H., today announced that the United States Patent and Trademark Office has granted the company a U.S. patent, which addresses the company’s application of technology that integrates information from multiple mammography images, including prior exams.

“We are continuously working to enhance our CAD offerings, including the development of technologies that will further improve CAD performance for radiologists,” said Ken Ferry, president and chief executive officer of iCAD.  “It is a strategic priority to expand our portfolio of patents that protect our intellectual property and the innovation that powers iCAD products in the detection of cancer, and we are delighted to be granted this new patent.”

This is the first patent issued to iCAD in 2008. Last year, the company was awarded four patents, including one related to CAD for virtual colonoscopy.

The company, which offers solutions for both digital and film-based mammography systems, has a total of 24 granted patents and 21 patents pending worldwide.

It is in the process of developing CAD solutions for use with virtual colonoscopy to improve the detection of colonic polyps.
