Breast cancer is the most common form of cancer. The diagnostic methods of breast cancer include mammography, ultrasound, and MRI. Nuclear imaging techniques generally have a secondary role in regional assessment and therapy follow-up. Optical imaging has shown to be very promising technique and is expected to play a very vital role in diagnosing the breast cancer.
This article will give you an insight on the various techniques used for optical imaging. Optical characterization of the breast has been attempted since 1929 in the form of a diaphanography or shadowgraphs of the breast tissues. This method successfully detected large, highly vascular malignant tumors but failed to achieve sufficient specificity and sensitivity. With the numerous scientific and technological advances in tissue optics since early 90’s, optical mammography is considered as a feasible technique with levels of…
