ABSTRACT:
An apparatus and method for monitoring a temperature around a point of clinical interest. The apparatus has a sensing surface carrying a plurality of temperature detectors in a regular spatial outer disposition around a central detector. A signal processor computes the highest temperature difference between any two outer detectors and the central detector and compares the highest difference with a predetermined number of temperature domains or ranges. The signal processor activates an output device to provide an indication of the correlation between the highest determined temperature difference and the temperature domains. The output device comprises three different colored lights to provide an indication of normal, doubtful or abnormal correlation. In another embodiment, the output device is a graphical display having a pattern of the organ to be examined as a background and a luminous point on the display, which is either not lit, flashes with a low frequency, or is continuously lit. In another embodiment, the output device is an acoustical device with three different tonalities or sound patterns.
