Malodoznaya digital X-ray machine (MTSRU) "Siberia-N", referring to the one-coordinate scanning system, was established at the Institute of Nuclear Physics. GI SB RAS Budker the detector based on multiwire proportional chamber, and is well known to practicing radiologists. In December 2001, in X-ray department of our hospital was established last modification MTSRU "Siberia-N" with a new detector - multichannel ionization chamber (MIC) developed by the INP them. GI Budker and produced by enterprises of the industry - integrated plant "(city of Woodland, Sverdlovsk reg.). Application of the MIC, greatly improving the performance MTSRU by increasing the frame size, increasing contrast sensitivity, increase the spatial resolution.
Over the last 4 months of operation of the equipment has been studied about 3 thousand patients. MTSRU "Siberia-N" well established in studies of the chest: excellent visualized lung parenchyma and lung picture elements, in all cases informative research or exceeded or was comparable to conventional radiography.
were obtained encouraging results in the study of the paranasal sinuses, where the well solve the main problem diagnosis - assessment of pneumatization of the sinuses and the status of their bony walls, and the vertical position of the patient can reliably detect fluid in the sinuses.
MTSRU use to diagnose diseases of the skeleton in our opinion has some limitations associated with a worse compared with film rendering technology of thin cortical bone plates and beams. INP conducted refitting in part increase the spatial resolution will enhance its ability to diagnose diseases of the locomotor apparatus.
are encouraging first results MTSRU for the diagnosis of acute surgical diseases - intestinal obstasction and detection of free gas in the abdominal cavity with perforation of a hollow organ, as well as to capture images of the esophagus and control passage of barium suspension through the intestines. Another interesting experience with MTSRU in contrast studies of the urinary system (antegrade and retrograde pyelography, contrast urography). However, it must be admitted that the investigation of urinary tract reliably determined only by the rather large concretions (more than 0,3 cm). In general, the inability to scan in the horizontal plane, somewhat limits the ability of contrast studies.
undeniable advantage of digital radiography should recognize the low radiation exposure to the patient. Thus, the effective dose to the patient during radiography of the chest in a straight line projection, as a asle, does not exceed 15 mSv. Low radiation exposure allows to conduct control X-ray examinations with greater frequency.
obvious is the economic efficiency of MTSRU "Siberia-N" in the multidisciplinary hospital clinics. Under the current average load 35 studies per day economic effect on an annualized basis of 150 thousand asbles.
high consumer factors MTSRU "Siberia-N", equipped with the MIC, can recommend it for widespread use in the outpatient and inpatient settings. In our opinion, should continue to work on further improvement of the installation in the direction of reducing the scan time, optimization of shooting modes, translation software in the format of DICOM, implementation blizkofokusnogo scanning, creation of universal tripod.
