Abstract
Abstract An apparatus for monitoring the condition of body organs comprises detector means having a plurality of sensors, each of the sensors being effective to detect the condition of a body organ and to provide an output signal related to the detected condition, and means operatively connected to the sensors and effective to compare the output signal of each sensor with a predetermined nominal output signal corresponding to predetermined conditions of the body organs. Means are operatively connected to the comparator means and to the sensors to select those output signals bearing a predetermined relation to known output signals. The apparatus may be used in conjunction with an indicator material which is injected into the blood stream for passage through the specific body organs to be monitored. A radiant energy source is adapted to be positioned proximate the body organs so that the rays may be directed through the organs and through the indicator material, thereby to provide an output signal at the sensors proportional to the intensity of the rays passing through the body organs and the indicator material. In the preferred embodiment, the detector means comprises a plurality of spaced sensors which are arranged in a given array so that at least several of such sensors are positioned over the body organs to be monitored.
