Microwave Radiometry |
Microwave Radiometry is based on
measuring the intensity of natural electromagnetic radiation from a patient's
tissue at microwave frequencies. This intensity is proportional to the
temperature of tissue. The change in temperature (thermal abnormality), that is
a basis of earlier detection of breast cancer, may be caused by increased
cancer cell metabolism.It should be noted that thermal changes proceed to the
anatomical changes that can be detected by traditional methods such as
ultrasound, mammography and palpation. Thus microwave radiometry is a very
promising method for the breast cancer detection at an earlier stage.
Basis of Microwave Radiometry
Microwave Radiometry is based on
measuring the intensity of natural electromagnetic radiation from a patient's
tissue at microwave frequencies.This intensity is proportional to the
temperature of tissue. So we can say that microwave radiometry allows one to
measure the internal temperature and display it on the monitor.
Difference between Microwave Radiometry
and Infrared Thermography
The main difference between well known
infrared thermography and microwave radiometry is that the former allows to
read and display the skin temperature, when the latter indicates the internal
temperature.
Advantages
of Microwave Radiometry
1. Non-hazardous
Microwave Radiometry is non-hazardous both to the patients and to the personnel taking the thermograms, as during the examination the intensity of natural electromagnetic radiation from the patient's tissue is measured.
2. Non-invasive
Temperature is measured non-invasively.
3. Earlier detection of
diseases
Thermal changes proceed to the anatomical changes that can be detected by traditional methods such as ultrasound, mammography and palpation. Thus microwave radiometry is a very promising method for the breast cancer detection at an earlier stage.
4. Detection of fast growing
tumors
The specific heat generation in the tumor is proportional to the grow rate of the tumor. So fast growing tumors are "hotter" and they are more contrast in thermograms. Thus microwave radiometry is an unique method that allows to detect first of all fast growing tumors. Using microwave radiometry (RTM-Diagnosis) in conjunction with other tradition methods allows to select patients with fast growing tumors.
5. Ability to detect
patients with increased proliferate activity of cells
The important feature of the microwave radiometry is that it can distinguish proliferative mastopathy and fibroadenoma from non-proliferative mastopathy and fibroadenoma. So the method allows to select patients who risk to have breast cancer.
6. Ability to monitor
treatment
Microwave Radiometry is non-hazardous both to the
patients and to the personnel taking the thermograms, so it can be effectively
used for the monitoring of the treatment.
