This paper presents the design and implementation of a one-chip camera device for capsule endoscopes. A prototype image sensor chip which has 320 times 240 effective pixels was fabricated using 0.25 mum CMOS image sensor process. This experimental chip integrates functional circuits required for capsule endoscopes and digital image transmission function. The integrated functional blocks include an...
The two-dimensional (2D) gel electrophoresis technique is used by biologists to separate complex protein mixtures. The digitized format of the 2D gel stored in a database offers the biologist a wider range of analytical research opportunities to find the key affecting the human health. However, the 2D gel image access on the Internet can be slowed by the network's bandwidth problem. In this paper,...
We study in simulation the properties of a transmission CT system using two fan-beam sources both illuminating a single detector. Using traditional X-ray sources, such a system would be expensive, slow, and unwieldy. With the development of new X-ray sources based on nanofabrication methods, however, such a dual-source system becomes feasible. The principal advantage of the new geometry is that a...
