Seed analysts need to identify seeds, and seed catalogs are used as a reference to accomplish this task. Conventional seed catalogs supply two-dimensional photographs and hand-drawn diagrams. In this study, a new, three-dimensional representation of seeds is developed to supplement these traditional photographs and drawings. QuickTime VR is a promising method for viewing three-dimensional objects on a computer screen. It permits manipulation of an object by rotating and viewing it from any pre-specified angle at an interactive speed, allowing the viewer the sense of examining a hand-held object. In this study, QuickTime VR object movies of seeds were created as interactive "movies" of seeds that can be rotated and scaled to give the viewer the sensation of examining actual seeds. This approach allows the examination of virtual seeds from any angle, permitting more accurate identification of seeds by seed analysts.

Endodontic treatments are routinely done with the help of radiographs. However, radiographs represent only a two-dimensional image of an object. Failure to identify aberrant anatomy can lead to endodontic failure. This case report presents the use of three-dimensional imaging with cone beam computed tomography (CBCT) as an adjunct to digital radiography in identification and management of mandibular second molar with three mesial canals.

Dr Ward points to two major problems that we discussed in our paper. At the time this study was begun in our neonatal intensive care unit, only M-mode echocardiography was available. We agree our methods were relatively gross estimations of ductal patency, and we are presently studying the effect of phototherapy using two-dimensional and Doppler echocardiography. The second flaw of nonblinding was an extremely difficult one to solve in our unit. Those physicians involved in the study spent considerable time in the unit and, even if shields were removed during the scheduled daily examination, it would be difficult to truly blind observers because shields would have been replaced.
