Objective-
Automatic detection of micro aneurysm .
Essential step in diagnosis and grading of DR
First stage diagnosis for diabetic retinopathy
Methodology Statement
Specific absorption between melanin, OxyHb & DeoxyHb is used in MSI with their concentration levels.
Concentration maps are used to detect many tissue disorders
Wound infections, edema, lynph edema and early stage pressure ulcers.
How it Works !!!!
A traditional MSI system includes two major components CCD camera and filter device.
The filter steps in a certain wavelength while camera captures one image at a time at one wavelength.
This process repeats until all required multispectral images have been obtained.
Images are given to the calibration process one for each wavelength.
Images received will display tissue abnormality if any.
Advantages-
This Real-time MSI imager gives handheld, low-cost, real-time operation.
It is noninvasive, easy to operate which render it very suitable for home-based health care.
It is possible to instantly detect & discriminate
tissue abnormalities such as cancerous tissues.
