ty, spiculation, solidity and margin. The database contains both larger (greater than three millimeters) and smaller nodules. "There is a lot of discussion in the clinical community about the significance of small nodules," Armato said. The radiologists marked the smaller nodules to indicate their presence but provided more extensive information about the larger nodules.

The Lung Image Database Consortium (LIDC) was initiated by the National Cancer Institute in 2001 with the participation of five academic centers and expanded in 2004 by the Foundation for the National Institutes of Health to create the Image Database Resource Initiative (IDRI). "There was a huge commitment on the part of the NCI," said Armato, pointing out the "extent of academic and intellectual effort" marshaled toward the completion of the project.

The web site through which the database may be accessed is http://ncia.nci.nih.gov

The presentation "The Lung Image Database Consortium (LIDC) and Image Database Resource Initiative (IDRI): A Completed Public Database of CT Scans for Lung Nodule Analysis" by S Armato et al. will be at 8:30 a.m. on Wednesday, July 21 in room 201B of the Philadelphia Convention Center.

5) TACTILE TUMOR-IMAGING DEVICE

Chang Hee Won and his colleagues at Temple University have made a novel tactile tumor-imaging device by exploiting the optical properties of waveguides -- which are planar, flexible and transparent probes.

Light traveling in a transparent waveguide will normally not leak out because of the principle of total internal reflection; if the refractive index of the guide is more than that of the surrounding material, a light ray approaching the wall of the guide will be reflected back into the guide. If, however, the guide becomes deformed becau
