[Digital X-ray apparatus "Sibir'". Measurement of the value of a signal].

For objective measurement of digital detectors, the authors show it necessary to be limited to the quantum efficiency of recording for assessing the accuracy of measuring the value of a signal and to the frequency-contrast characteristics for estimating spatial accuracy. Since a computer is an integral part of the digital detector, this cannot be a basic obstacle to the application of the proposed procedure.

[Industrial production of the LDRD "Siberia-N" digital radiographic devices].

It is envisaged, as a key task, in the Federal Program on Tuberculosis Monitoring, that preventive measures and early TB detection is a priority. Fluorography, which is important for the recognition of pulmonary tuberculosis at its early stages, has been used in the diagnostics of pulmonary pathologies. However, according to the statistics provided by the Russian Ministry of Healthcare, around 80% of available medical equipment is now worn and obsolete. Owing to a fruitful research activity related with designing a digital low-dose X-Ray unit (Siberia-N) carried out by the Budker Institute of Nuclear Physics, Siberian Branch of the Russian Academy of Sciences (Novosibirsk), a certain progress can be stated in perfecting the fluorography equipment in Russia. The above unit incorporates all advanced achievements in the field of digital X-Ray diagnostics.

[Information technologies for scanning X-ray radiography].

Digital technologies have been widely used in X-rays diagnostics, including computer tomography, magnetic-resonance tomography, digital radiography etc. Digital technologies for image analysis essentially change all arrangements and procedures of preventive examinations made at patient-care facilities. As for digital fluorography, the basic principles of fluorography diagnostic room are standard but for one arrangement-the unit is controlled via a computer-assisted working place (CAWP) by the radiologist assistant; the room of radiologist is also equipped with CAWP. Admittedly, a key issue in general fluorographic examinations is registration of patients and preparation of them for the procedure. Contemplated in the paper are new potentialities of digital fluorography of big number of patients by low-dose fluorography (LDF, equipment manufacturer/Orel, Russia) which enhance the rate and quality of diagnostics.

[A digital radiographic device for medical diagnosis].

The paper outlines a digital radiographic device which records radiation by scanning with a one-dimensional multiwire proportional chamber connected on-line to a computer. The device drastically reduces a dosage load on patients, improves the diagnostic potentialities of projectional radiography, yields quantitative diagnostic information, creates special diagnostic programmes, has fast-access and fire-safe archives. The device may be used for general-purpose radiographic examinations and it has advantages when used instead of conventional fluorographs.
