Blood
is a specialized connective tissue in fluid form that flows through the entire
body of a person or animal. Blood flow is the continuous circulation of blood through the cardiovascular system to body tissues and organs. An adequate
amount of blood supply is necessary for the proper functioning of all body
organs. This is vital as the blood carries and supplies body tissues and organs
with its daily metabolic requirements while it also gets rid of any waste
arising from tissue metabolism. Various diseases impair supply of blood to the
organs. Hence the measurement of the blood flow can therefore provide essential
information for the diagnosis of diseases. Since changes in blood flow occurs
with the very initial stage of disease, therefore with a fast, reliable and
non-invasive blood flow measurement technique, the physicians would be provided
with new options for early disease diagnosis.
