Project summaryThe purpose of the project is the development of a method of X-ray medical diagnostics and equipments ensuring a minimum radiation dose, and an automatized information reference directory system for the medical emergency in conditions of extreme situations such, as industrial and traffic accidents, natural calamities and so on.
In the course of the project fulfilling it is supposed to investigate processes in the X-ray emitting tubes, with the purpose of a raise of tubes reliability [1, 2, 3], to construct a X-ray apparatus with the improved operational features and enlarged (in 1,5... 2 times) service life.
Authors suppose to use materials applied in nuclear energy industry and space technology such as monocrystals of molibdenium and tungsten, monocrystal ceramics and its combinations with metals and graphite for the manufacturing of X-ray tubes and other details of X-ray emitting apparatus.
The experts of VNIIEF, having rich experience in development of X-ray equipment, will increase quality of apparatus and adapt them for field conditions.
It is suggested to accomplish X-ray imaging with the help of the closed - circuit TV set. Specially devised portable digital unit of the frame grabber type inputs digitized X-ray images into a computer (number of pixels 720ґ580; 8 bits) for consequent handling and storage.
Transmission and visualization of X-ray images will be realized by modern compact and easy transportable equipment. New software should be worked out to provide high quality visualization of X-ray images, to mark out abnormal regions, to emphasize contours, to measure geometrical parameters of images.
It is supposed, that the performances of such installation will be not worse those of X-ray film (threshold contrast ~1ё 2 %, space solution ~2 ё 7 mm-1, time of obtaining of a snapshot ~some seconds).
The low threshold of sensitivity (~0.2 mP) will allow considerably lowering a level irradiation of patients, to improve work of medical personnel.
The working out of a database for operative storaged images with their subsequent transfer into the clinical stationary database will be also envisaged. The database should provide the storage of the text information about the patient, diagnosis, doctor's conclusion after examination of the patient, and the necessary radiographs.
The digital X-ray TV unit should be provided with an automatized information reference system. Such system will ensure physicians and surgeons an information support in the sorting patients out, in diagnostics and choice of method of treatment in circumstances where the shortage of time takes place during the mass arrival of victims.
As a result a model of a digital X-ray diagnostic system for use in emergency by medical teams in field hospitals will be made.
Such equipment can find many applications in the industry, e.g. for tires quality checking, for nondestructive control of welded joints, etc.
Highly skilled specialists in X-ray equipment designing and digital imaging which before were involved in nuclear weapons programs will perform the work. Specialists in the medicine of catastrophes take active part in the work.
It is important for the successful promotion and accomplishing of the project to have foreign collaborators. The type of collaboration can range from occasional consultations to intensive joint research efforts. The role of foreign partners should be stated in the work plan (e.g. the frequency and purpose of exchange visits, types of information which will be provided in both directions, complementary research activities to be carried out by the partner, etc).
