Contact Regulation Thermography

  • CRT 2000© is a computerized medical device used for screening human health conditions. After 30 years of research, European doctors in the 1970s established that heat generated in the internal organs of the human body reaches the skin by means of convection through the blood vessels, and is then transferred in the non-vascular uppermost skin layers of the skin surface known as visceral cutaneous reflex (VCR).


    A thermogram from the CRT2000™ provides status of an individual’s health at a point of time, and a profile of each of their organs and vital systems and how his/her body functions and copes under stress. Even at the earliest stages of the disease process, before symptoms show, there are minute, detectable changes in circulation patterns and thermal characteristics of the major organs not detectable by any other procedure or technology. By measuring the body’s reactions to cooling stimuli, the CRT 2000™ identifies the progressive pattern of a disease long before symptoms of a disease manifest.


    The 30 minute procedure tests the ability of the patient’s tissues to respond to the stress of a colder temperature. PDC ’s clinical research has been standardized to take 10 minutes for the body to stabilize and produce the reactions of the internal organs upon the skin. The skin temperature is measured on 119 precise points on the body. After adapting to room temperature, the first set of measurements is taken. The patient spends the next 10 minutes undressed in a 20-23°C room, creating a stress on the organs as they respond to the body’s need to maintain homeostasis. The measurements are repeated and the test is concluded.


    The CRT 2000™ measures the skin’s VCR temperature with the aid of contact sensor and converts the heat energy on the skin into electronic data signals that are displayed on a computer monitor. The heat data are analyzed by the company’s analytic server based in Canada through the Internet. A comprehensive report shows how the patient’s various organs and neurological control systems react and the doctor knows what they mean to understand the patient’s health situation.


    PDC ’s analysis system is based on the results of patient profile readings spanning more than twenty-five (25) years, the collective experience of PDC ’s medical board and contributing doctors, and various published works. This research shows that the pattern of progression of each disease is unique and has its own individual thermal characteristics and markers. The system compares patient measurements with these patterns.


    CRT 2000™ stands out distinctly as a totally non-invasive preventative health care device unlike other methods available at the moment e.g. X-Rays, Mammography, MRI. Ultra Sound, Pet Scan etc.    
    Eidam CRT 2000™ Thermographic System


    The CRT 2000™ Thermographic System is a non-invasive, radiation-free, reproducible thermographic tool that measures the temperature of pre-determined skin points and analyzes that data to provide a healthcare practitioner with information that may be indicative of irregular body functioning.

How it works

  • The 30 minute CRT examination is a non-invasive, painless procedure that involves gentle contact of a skin temperature sensor on the surface of a patient’s uninjured skin to take two readings consisting of 119 measurements each:


    1. First Reading
    Consists of 119 measurements on pre-determined skin temperature points as the patient progressively undresses.

    2. 10 Minute Wait
    The patient waits while disrobed, inducing an autonomic response to the cooling stimulus of room temperature.

    3. Second Reading
    The 119 temperature measurement points are repeated.

    4. Thermogram, Profile & Report
    The patient’s data is stored on the CRT computer and then sent, via a secured internet connection to Eidam’s server, where the data is compared with over 1.5 million existing thermographic data. Within seconds, a Thermogram, Reaction Profile and Patient Evaluation Report are created and sent back to the healthcare practitioner. This information may be indicative of irregular body functioning, which the health care practitioner may then decide to investigate

"I use the CRT daily as a tool to conduct in-depth diagnoses and therapy. Additionally, it allows me to receive a complete picture, not just a partial one, of the patient’s health. It helps me recognize the links between physical and psychological disorders. I do not know of any other diagnostic tool that can demonstrate the regulation capability of humans like the CRT can

Breast cancer care

"In 2004, a woman diagnosed with breast cancer, using the traditional diagnostic tools of mammogram and MRI, underwent reconstructive surgery to build up the affected breast that had been removed through the previous mastectomy. This procedure required the transplantation of tissue from the unaffected, right breast to the area to be reconstructed on the left side. However, the lab results indicated that the right breast was also affected by cancer, as the cancer had metastasized from the left breast to the right.

Follow-up diagnosis using mammogram and MRI did not confirm the lab results; the radiologist sent her a report giving her a clean bill of health! The woman then underwent a CRT scan. It indicated what the mammogram and MRI failed to show: cancer in the right breast.
