1. A method of determining an emergence of an ulcer on a given portion on at least one foot of a patient, the method comprising: providing one or more processors; providing an open platform for receiving at least one foot, the open platform having a plurality of temperature sensors; generating, using the plurality of temperature sensors, a plurality of discrete temperature data values after receipt of the at last one foot; forming, by at least one of the one or more processors, at least one thermogram of a sole of each of the at least one foot of the patient from the discrete temperature data values, each thermogram comprising a spatially continuous data set of two-dimensional temperature values across the sole of one foot; determining, by at least one of the one or more processors, whether the at least one thermogram presents at least one of a plurality of prescribed patterns; said determining comprising comparing the at least one thermogram against a prior thermogram of the same foot; and producing, by at least one of the one or more processors, output information indicating an emergence of an ulcer on a given portion on the at least one foot, said producing being a function of whether the at least one thermogram is determined to present the at least one prescribed pattern, said producing also being a function of the comparison, the prior thermogram showing non-ulcerated tissue at the given portion.
