Project summary

The purpose of the Project is development of roentgen-television introscope earmarked for clinical application and mass examination of patients. Operational characteristic of the introscope will meet requirements of spatial resolution at minimum dose of a patient’s irradiation. At the same time the irradiation dose will be significantly lower in comparison with traditional roentgen equipment.
Trend of development of modern medical roentgen-television equipment basically implies improvement of roentgen image through perfection of their electronic part. This leads to complication and increasing their cost, disregarding the other purpose that is not less important – decreasing of a beam loading per patient.
Preliminary theoretical and experimental investigations on optimization of parameters of the equipment being developed have led to creation of an experimental roentgen-television scanning introscope with the dose of irradiation that is 500-800 times less than when fluorography by means of traditional methods. Estimations and results of experimental investigations have been confirmed by means of experimental sample investigations of roentgen-television medical introscope. The experimental sample was clinically tested in Tbilisi Cancer Center in 1993-1994. According to the conclusions of expert-roentgenologists the obtained results were positive. The sample is being used in the above mentioned Cancer Center even now.
The results of the investigations were reported at Symposium of Georgia on Development of the Projects and Conversion organized by ISTC in Tbilisi (May 15-18, 2000).
The Introscope is approved even by specialists working on this problem (Mr. W.N.Mcdicken from Edinburgh University).
The developed Introscope has grained Georgian Patent (#1).
In the result of the Project there will be developed a medical roentgen-television initroscope approximating to roentgen equipment with electronic-optical converter by its spatial resolution capacity parameter (size), but it will be significantly low (in 500-800 times) by the parameter of dose irradiation of a patient. There also will be developed technical documentation necessary for an introscope production on the basis of microprocessor and computer element base taking into account modern design.
The leading participants of the proposed Project are the scientists and specialists in radiation physics, electronics, mechanical engineering, computer systems. They have great experience of scientific and experimental investigations in the field of radiation technique, nuclear engineering and special means of technological and inspection.
The Project participants have developed, produced and investigated several articles of military technique and special radiation means of ammunition control and special military structures, roentgen-television systems of control technique earmarked for technical diagnostics and technological control having been implemented in the USSR military enterprises.
The Project participants are the authors of various inventions and scientific works the major part of which are published in secret scientific-technical articles “Issues of Special Mechanical Engineering”, “Ammunitions”, “Military Technique”, etc. and the collection of scientific-technical seminars and conferences’ thesis and reports in the sphere of special mechanical engineering and military technique.
The proposed Project meets the requirements of ISTC as it will engage the scientists and specialists involved in arms production earlier and the results of the Project will be used for peaceful reasons, particularly, environment protection, in the ISTC case. On the basis of the developed documentation it will be possible to produce medical introscopes that also meets the ISTC commercial aims.


The International Science and Technology Center (ISTC) is an intergovernmental organization connecting scientists from Kazakhstan, Armenia, Tajikistan, Kyrgyzstan, and Georgia with their peers and research organizations in the EU, Japan, Republic of Korea, Norway and the United States.


ISTC facilitates international science projects and assists the global scientific and business community to source and engage with CIS and Georgian institutes that develop or possess an excellence of scientific know-how.
