Constitutive Values
Because modeling bioheat transfer is of the utmost importance in proper device or heating protocol design, constitutive values of various tissues of the body had to be measured early on in the history of bioheat transfer.
Of particular importance were the values of specific gravity, specific heat, thermal conductivity for the various tissues in the body e.g. skin, fat, muscle, bone, and blood. Today, such values can be easily found in various handbooks and study publications such as the CRC Handbook of Mechanical Engineering (2nd Ed.) or the Report of the task group on reference man (1975).
To illustrate the detailed knowledge that is required by the bioheat transfer community, The CRC Handbook of Mechanical Engineering includes a nearly 2 page table of value for thermal conductivity of various organs including but not limited to: kidney, aorta, arterial plaque, blood, liver, spleen, heart, muscle and tumor.
Because of the importance of blood perfusion on thermal equilibria in the body, blood perfusion values were also pursued early in the history of the field. The CRC Handbook of Mechanical Engineering's chapter on Bioheat Transfer includes a nearly 6 page table of blood perfusion values for a similar variety of tissues as the table for thermal conductivity. Greater discussion on the effect of blood perfusion on heat transfer is given in Section 2.

Famous quotes containing the words constitutive and/or values:
“Madness is the absolute break with the work of art; it forms the constitutive moment of abolition, which dissolves in time the truth of the work of art.”
—Michel Foucault (1926–1984)
“[University students] hated the hypocrisy of adult society, the rigidity of its political institutions, the impersonality of its bureaucracies. They sought to create a society that places human values before materialistic ones, that has a little less head and a little more heart, that is dominated by self-interest and loves its neighbor more. And they were persuaded that group protest of a militant nature would advance those goals.”
—Muriel Beadle (b. 1915)
