U.S. patent 7,463,761 includes claims for the general technique of acquiring two-dimensional digital slide images, and using this two-dimensional image as a map for subsequently acquiring three-dimensional images known as z-stacks. “The ability to create and view z-stacks while a glass slide is still in the scanner is critical for specimens that have multiple focal planes, such as frozen sections for example,” said Ole Eichhorn, Aperio’s chief technical officer.
The ’761 patent also includes claims for the high-performance remote viewing of three-dimensional digital slides across a network, including the Internet. “The ability to create and efficiently view three-dimensional whole slide images makes it possible for Aperio to extend the benefits of digital pathology to the field of cytology, including Pap smears,” said Dirk Soenksen, CEO of Aperio. “The recent expansion of our patent portfolio to encompass TDI-, fluorescence- and 3D-scanning, viewing, and analysis continues to reassure customers that Aperio has the broadest freedom to operate in all niches of digital pathology.”
