چکیده
text from WO2001072212A1) A method and apparatus for electronically performing a visual field test for a patient. A visual field test pattern is displayed to the patient on an electronic display device and the patient's responses to the visual field test pattern are recorded. A visual field representation is generated from the patient's responses. The visual field representation is then used as an input into a variety of diagnostic processes. In one embodiment of the invention, a series of visual test patterns of varying contrast are presented to a patient in order to construct a three-dimensional visual field representation wherein contrast sensitivity is plotted against a Z-axis.

متن کاملVisualisation and Analysis of Bibliographic Networks in the Biomedical Literature: A Case Study
In this article, we present a case study on the analysis of the biomedical patent literature. For a set of Unilever’s patents we show how to apply visual datamining by applying dimension reduction to document, term, and author data and interactive exploration of 3D scatterplots. We complement this approach by focusing on author and document networks, which we analyse with PSIEYE, a tool for the...
