Abstract:
Medical science relies on technology now more than ever. For both diagnosis and treatment
blessing of technology is exploited. Diagnosis of disease using technology comes in various
forms. Imaging is a particularly attractive diagnosis methodology. Among the existing diagnostic
imaging techniques ultrasound has gained much popularity over the years.
Apart from the regular ultrasound imaging techniques ultrasound has some special use.
Elastography is such an application of ultrasound. It is actually the imaging of the stiffness of
the tissue. Elastography is particularly efficient in diagnosing early cancer particularly breast
and prostate cancer. For example, breast cancer is diagnosed by invasive biopsy. But
elastography can reduce the rate of biopsy since a large fraction of the tumors of breast are
found to be benign. Unlike biopsy elastography provides instant result. It relieves the patient
from psychological stress to wait for the result. But elastography is much of a qualitative
technique. It can be unreliable at some cases. That’s why extensive research is being performed
to improve its quality.
In our thesis we have worked on two different aspects of the research. We have presented a
software tool that can be used for improving the computation time in elastography. Also, we
have proposed a concept of using smooth window functions to improve the image quality and
presented some experimental results.
