th row advantages compared with traditional screen-film
systems, the main one being associated with a significant reduction in
radial loads on the patient and staff. And the introduction of digital techniques in
fluorographic screening system allows to get the finished image in
seconds, which contributes to a significant reduction in diagnostic
period and have a positive impact on the level of prevention and treatment of diseases.
MTSRU "Siberia-N" is a system of scanning type, in which the image is formed
registration of a thin fan-shaped X-ray
with one-coordinate detector by moving it along the studied
object.
Respiratory movements of the patients, as well as other movements occurring at the time
take the picture, do not cause "blurring" the image. This is due to
extremely short exposure time of one line - 2,5 ms. At the end of
shooting in the computer memory stored digital image, representing a matrix of
1024h2048 numbers.
Set comes with two workstations (AWS)
in the local network with the ability to connect to a computer network
medical facility. MTSRU software package asns on Windows 95/98/ME/NT/2000
on-line and helps the technician in selecting optimal RTL / C
for conducting survey on the entered data about the patient and the field survey. ARM
rentgenolboranta designed for both control the scanning process and
health checks MTSRU. The database of patient data entered
standard parameters that are necessary for X-ray.
The resulting digitized images can significantly simplify the process of archiving
fluorogram on compact disc with a long shelf life and
easy to organize a compact and easily accessible archives of X-ray. Archive with
instant access to any information beneficial from an economic point of view,
safe to fire on, does not require special facilities.
to restrict unauthorized access to the archive data is entered key
protection. Software shell ARM doctor is simple and easy to operate, equipped with
various image processing functions in order to optimize it - an increase
size image on the display screen, the inversion of the image, change brightness and contrast
as a whole image, and in randomly selected rectangular
area. High dynamic range (latitude - 480) allows
study as low-contrast and high-contrast objects on a single image
simultaneously, which largely expands its diagnostic significance.
Especially important to obtain quantitative characteristics of the image - this definition
distances, angles, size of organs or pathologic entities. When
further diagnosis is possible to measure the relative density at each point
snapshot or average relative density in arbitrary image fragment.
Displaying multiple images at the same time allows a doctor to do
full comparison of survey results. It can be direct and lateral projection
or images taken at different times and stored in the archive.
Immediately after the analysis of image formation is carried out medical
description and the issuance of the final diagnosis in hard copy and, if necessary
, photograph, printed on an inkjet printer. For a substantial
accelerate image processing doctor uses a ready-made templates (forms)
descriptions and conclusions that can be edited. On the analysis and formulation of conclusions
one image takes an average of 10 minutes.
Among other advantages is the possibility of mathematical processing
digital images using advanced algorithms. This allows
improve image quality by converting to a form most suitable for
visual analysis, which allows a doctor at an earlier stage to identify
illness and put a definitive diagnosis. Now such techniques are used
processing, such as emphasizing the contours or additional extension of the range
densities simultaneously observed on the screen.
software is constantly evolving and being updated on previously purchased
installations. In case of necessity is possible to develop additional programs
processing the information received, together with specialists

on a single architecture and to create a common ideology to unite them in a
a single information system of medical institutions.
most promising direction for further development of digital radiography
is to create a single network of computer links between hospitals.
Modern means of communication and data transfer will advise patients
and their physicians, being on them at a distance, even on another continent
, and the consultant is not transferred to the subjective report of the examiner
doctor, and the primary diagnostic information.
transfer of standardized data on the patient's condition allows a remote consultant
equalize the chances of patients to receive expert assistance when
we are talking about the very important issue - the correct diagnosis. In many cases
direct communication is not required, and tele-
held in deferred mode, when all the necessary medical documentation, including
studies and measurements, the consultant sent through the communication channels
in advance, the consultant looks at it in convenient time, prepares
opinion and sends it back.
Introduction MTSRU "Siberia-N" in the practice of public health should be the basis
reforming the existing system of mass prophylactic examinations
population for early diagnosis of tuberculosis. This is facilitated by a
relatively low price for fluorographic installation.
