Abstract
Summary
An electronic light source for in vivo transillumination and photography of microcirculatory events within solid organs is described. This high intensity light source was balanced for daylight color film and was placed directly below the organ in the direct optical path of the microscope. To minimize detrimental effects of normal organ function, the temperature of the light carrier and flash tube at its tip did not exceed normal body temperature. This optical system was combined with a constant light source for viewing and focusing.
