Measurements for medical diagnostic purposes measure the temperature of parts of the body to diagnose illnesses and for monitoring dynamics of an illness during treatment. This increases accuracy and clarity and simplifies technical implementation. An image of the region of the body of a biological subject under investigation is input into a computer database, with the image being output to a monitor of the computer, wherein the measurement points for measuring the temperature in the region of the subject under investigation are displayed in the image of the subject on the monitor screen and, once the measurements have been taken and the results of the measurements have been processed in the computer, an image of the temperature field is generated by a computer.
