5.1. The device set consists of the following items:
· Internal temperature sensor with the antenna (ITS)
· Skin temperature sensor (STS)
· Data processing unit (DPU)
5.2. According to physics laws, any object above zero emits radiation at all frequencies and, in particular, at microwave frequencies.
This feature of heated body is used for measuring averaged internal tissue temperature and detecting thermal abnormalities of internal tissues (higher or lower temperature of internal tissues).
The noise power received by the antenna contacted an evenly heated absorbing object is:
P=K*T*B, where
K - Boltzmann’s constant
B - System bandwidth (Hz),
T – Temperature of the biologic object
Therefore the power noise received by antenna is proportional to the tissue temperature.
When the object temperature is 309°K, i.e. 36°C the noise power received by the antenna is 3x10-13 Watt. This value corresponds with the noise generated by the antenna. Special methods are applied for receiving and processing signals.
Bioobjects that usually examined consist of several layers (e.g. skin – fat – muscle). The radiation power passes through all parts of tissues with different loses and different temperatures, so the temperature measured by the antenna is not equal to the physical temperature of the examined organ, but depends on the temperature of other body parties and loses in these parties. Also the antenna does not match the measured object absolutely. That leads to errors that are eliminated by the methods described later.
The techniques of diagnosing diseases is explained in Doctor’s Manual.
The device is a modulated null-radiometer with a slipping circuit for compensating reflection between the biological object and the antenna.
The functional scheme is illustrated in Fig. 1. When the temperature is measured, the antenna contacts the patient’s skin at the projection of the examined organ. The antenna receives microwave radiation from the examined organ as noise at microwave frequencies and the signal is amplified in ITS (2).
 |
The signal amplified in ITS is transmitted to the DPU (data processing unit), where it is processed (3).
The voltage from the skin temperature sensor (STS) (4) is transmitted to the DPU too. The skin temperature sensor is non-contact infrared frequencies receiver.
The modes are switched by the buttons located on the front cover of the data processing unit. The internal and skin temperature values are displayed on the 3-digit temperature indicator as degrees Celsius with discreteness of 0.1.
Data processing unit produces serial digital signals for interfacing with PC.
On the front cover there are a temperature indicator, "ÐÀÄÈÎÄÀÒ×ÈÊ" (INTERNAL TEMPERATURE SENSOR) and "ÄÀÒ×ÈÊ ÒÅÌÏÅÐÀÒÓÐÛ ÊÎÆÈ" (SKIN TEMPERATURE SENSOR) button, and "ÑÅÒÜ" (POWER) power indicator. On the back cover of the DPU there are connectors for connecting with the internal temperature sensor (15-pin and coaxial connector), as well as a PC 9-pin connector, a coaxial connector for the internal and skin temperature sensors (analog signals that are on this connector has positive polarity with scale factor of 0.01 V/degree). Also the power switch and fuses are on the back cover.
6.1. The radiometer complies with the requirements of the national standards ÃÎÑÒ Ð 50276.0-92, class 1, type B.
6.2. The safety measures for RTM-01-RES is similar to the general safety measures for any electronics.

6.4. Devices connected to the RTM-01-RES must comply with the requirements of the national standards ÃÎÑÒ Ð 50276.0-92, class 1.
6.5. When PC is used, a processing unit, a monitor and a printer must be located at 1.5 m distance and more from the patient.
6.6. The radiometer and the PC must be connected to tripolar separated sockets.
7.1. The radiometer must be used indoors and all climatic requirements defined in Passport must be met.
7.2. The radiometer is transported in the pasteboard box. The device must be unpacked indoors at room temperature.
7.3. Open the box and take off the polyethylene cover from the units.
7.4. Check to make sure that all items indicated in paragraph 4 are delivered.
7.5. Connect the ITS with the data processing unit (coaxial and 15-pin connectors). Connect the STS with processing unit (9-pin connector). The connectors are on the back cover of the data processing unit.
7.6. Insert a two-pin plug of the radiometer into 220 V sockets. Press the "Ñåòü" (Power) button located on the back cover of the DPU. The power indicator located above the "Ñåòü" button and the “Íàãðåâ” indicator located on the ITS will be on.
7.7. The device must be heated for 30 minutes.
7.8. Choose the skin temperature mode (mode 2): press the “ÄÀÒ×ÈÊ ÒÅÌÏÅÐÀÒÓÐÛ ÊÎÆÈ” (Skin temperature sensor) button. The below temperature indicator will be on.
7.9. Connect the skin sensor surface with the skin of the palm near foundation of the thumb. Displayed temperature will be 30…35°C.
7.10. Switch to the internal temperature mode (“ÐÀÄÈÎÄÀÒ×ÈÊ”). The indicator that is above will be on.
7.11. Connect the antenna surface with the right or left neck side at the 5-cm high from the collarbone. Displayed temperature should be about 32…36°C. Checking device is complete.
7.12. When a PC is used, connect PC units in accordance with User’s Manual. Plug the cable from DPU into the serial socket of the PC (Com1 or Com2).
7.13. Turn on the radiometer and the PC. Install the RTM-Diagnosis software. Choose Settings/Device interface. Set COM 1 or COM 2 option according to 7.12 clause.
8.1. For measuring the internal temperature (mode 1) put the antenna on the body at the examined point. Substances for improving antenna contact with the skin are not required. The entire antenna surface must contact the skin.
8.2. Read the temperature on the temperature indicator. When the mode 1 is used the temperature displayed on the indicator may vary about the average temperature at ± 0.1...0.2 °Ñ; therefore values displayed on the indicator must be averaged.
8.3. The skin temperature is measured with the skin temperature sensor. Switch on the mode 2 (skin temperature sensor). The sensor must be perpendicular to the body surface and special facilities are used. The measurement time at one point is not more than 2 seconds. When the facilities for short distance are used the diameter of the investigated spot is 5 mm. For long distance it is 18 mm.
