The optometry in physical examinations is conducted manually at present and this method is neither precise nor efficient. After studying the standard logarithmic visual acuity charts which is popular in our country, we have designed an optometry system based on Client/Server Computing Mode. The system's architecture and its working principle are also presented in the article.
This paper explores brain CT slices segmentation technique and some related problems, including contours segmentation algorithms, edge detector, algorithm evaluation and experimental results. This article describes a method for contour-baed segmentation of anatomical structures in 3D medical data sets. With this method, the user manually traces one or more 2D contours of an anatomical structure of interest on parallel planes arbitrarily cutting the data set. The experimental results show the segmentation based on 3D brain volume and 2D CT slices. The main creative contributions in this paper are: (1) contours segmentation algorithm; (2) edge detector; (3) algorithm evaluation.
