Method and apparatus for early diagnosis of Alzheimer's using non-invasive eye tomography by Teraherts
First Claim
1. A method for early diagnosis of Alzheimer, comprising:
- a) generate a Terahertz signal;
b) split the Terahertz signal to a scanning system and an optical arrangement;
c) feed a signal passing though the optical arrangement to a Terahertz detector;
d) illuminate the eye lens with a focused scanning Terahertz beam from the scanning system;
e) redirecting the reflection of the eye lens into the Terahertz detector;
f) inserting the output of the Terahertz detector to an amplifier;
g) inserting the output of the amplifier to a control and display system;
h) wherein the method measures the amyloid layer of the eye and provides an early diagnosis of Alzheimer'"'"'s disease.

Abstract
The primary objective of the present method and apparatus is to provide a transportable diagnosis system for a reliable method to examine the conditions of a human eye lens. The method provides precise and safe technique for the early diagnosis of Alzheimer'"'"'s Disease (AD) which is not involved brain surgery or biopsy. The detection of deposited amyloid plaque in the eyes of the patient has been discovered to be a possible diagnosis solution. The disclosed method uses Terahertz waves in both time and frequency domains instead of laser for scanning the eye of the AD patient to precisely image the amyloid layer non-evasively in real time and to map the deposited plaque with high resolution which can easily distinguish the abnormality of an AD patient with the comparison of the patient eye lens test to the available signature of a normal person and the signature of a person with common age-related cataracts.
