FIELD : medicine.SUBSTANCE : invention relates to the field of measurement technology and can be used to measure the temperature in a magnetic resonance medium. Temperature measuring probe 130 for use in a magnetic resonance medium comprises elongated substrate 202, at least one electrically conductive high resistance path 200, 200a, 200b, 200a' , 200b' printed on at least one thermistor 204, which is located on the substrate and electrically connected to the path. Thermistor is made with the possibility of placement in thermal interaction with the patient in a magnetic resonance medium. In some embodiments, the printed path may be carbon, silicon based, or may be a doped semiconductor material.EFFECT : technical result is an increase in the accuracy and informativeness of the data obtained.15 cl, 5 dwg
