Abstract
The primary objective of the present method and apparatus is to provide a portable and new diagnosis system for quickly and reliably examining tissue conditions. The method uses the most advance miniaturized micro-opto-electro-mechanical systems (MOEMS) system for generating a rapid variable optical delay line capable of generating wideband terahertz pulses. The method detects and analyzes cancerous tissues by comparing a plurality of spectrum resolved images of suspected tissue without applying harmful agents into the tissue to facilitate interaction with illumination sources. The method employs non-evasive, real time terahertz imaging systems and techniques to diagnose tissue for detecting the presence of cancer. A map showing, which tissue is healthy and which is cancerous can aid in the accurate removal of cancerous tissue.
