To register the X-ray radiation, which passed through the chest, x-ray machine ProScan uses a silicon linear detector. To make a fluorography
, the detector is being moved along the chest horizontally together with a sector-shaped x-ray formed by the slit diaphragm. High quality images, lowest dose of investigation, convinient conditions for personal, easy requirements to x-ray room make this CXR (chest x-ray) machine better solution for mass screening compare to bucky based solutions. Specific features of fluorogrphy units
ProScan®-2000 and ProScan®-7000
Radiologist and assistant workstations.
- The silic linear detector does not need periodic maintenance. It provides spatial resolution in the patients plane of 2.2 Lp/mm for ProScan-2000 (3.2 Lp/mm for ProScan-7000). High efficiency of registration permits obtaining a direct short with 1% contrast resolution at only 100 mR in the patients plane for ProScan-2000 and at 250 mR for ProScan-7000.
- Chest X-ray machine protective cabin made of modern composite materials lowers personnel radiation exposure practically to the natural level.
- High frequency generator is connected to a 220 V ± 10% single-phase network with resistance up to 3 Ohm. To ensure proper operation, the majority of similar units need a 380 V ± 10% three-phase electric system with maximum resistance of 0.3 Ohm.
Both stations are equipped with the latest models of computers. Assistant workstation is equipped with a professional graphic monitor 20 inches, and that of the radiologist with the following monitors: ProScan-7000: professional medical monochrome monitor 20 inches WIDE IF 2002M* and a professional graphic 17 inches, ProScan-2000: professional medical monochrome monitor 24 inches.The ProScan software
enables the doctor to examine the images after fluorography on the big monitor, at the same time using the second one for work with the database. A professional graphical printer gives 256 gray shades and high spatial resolution on thermal paper. Herewith the image is equally informative on the monitor as well as on a hard copy. To print out periodical reports, the device is equipped with a laser office printer. DVD-RAM cartridges are used for archiving of the database and images. The competitive advantage of these media in comparison with usual DVD consists in a special box to provide protection to the disk surface from damages; besides, the disk can contain twice as much information. Thus, the holding capacity of such disk is 9.4 Gb (about 3000 images for ProScan-2000 or 1500 images for ProScan-7000). Today, it is one of the safest ways of information keeping, which is specially certified for storage of medical diagnostic images.ProScan® Software
meets the requirements of the DICOM 3.0. The program is being developed in close cooperation with radiologists that is why it contains not only generally accepted formalized protocols, but also the necessary forms of periodical reports. The program offers wide opportunities for processing obtained images through special filters to detect tuberculosis.
