Several methods have been developed for improving transillumination devices such that they may be effectively used for breast cancer examinations. Each of the methods involves a particluar technique for reducing scattered light. If light which passes straight through a breast can be distinguished from light which is scattered within the breast, better images can be produced. In addition, biochemical markers have been developed which associate with cancerous tissue and enhance the contrast by absorbing light of specific wavelengths. |
