The conventional hepatic function tests have many deficiencies, such as large blood sampling, non-continuous and etc., so a new non-invasive test method is studied. The dye of indocyanine green (ICG) is intravenously injected. Afterward two spectrum signals of the hemoglobin and the ICG are picked with the signal acquire system. In lab-view software platform an algorithm is introduced to calculate...
