This cross-arm unit is optimised for chest servey in standing and sitting patient’s position. Therefore its cross-arm does not rotates.
It provide spatial resolution from 2,5 to 3,2 Lp/mm. Device support is provided with cross-arms which cameras with CCD, X-ray tube and diaphragms with light localizer are fixed on. In all units the cross-arm can move in vertical direction to 1100mm. In ProGraph units the cross-arm have fixed focal distance 1000mm. The function of automatics helps the doctor choose required characteristics of survey. High frequency generator is connected to a 220 V ± 10% electric system with resistance to 1 Ohm.
The unit has special external storage element on hard disks for supplying of long-term storage of images. Capacity of storage allows place on hard disks image archives accumulated within 10 years of unit operation. Built inside storage software provides particular reliability of saved information and absolute archives reliability in case of one of hard disk death. In ProGraphв unit radiologist workbench is equipped with graphic monitor 24” (610 mm) for work with images, database and image description.. Assistant workbench in units is equipped with graphic monitor 20” (510mm) to fill in the database, operate X-ray unit and control image quality.
The unit is equipped with laser office printer for periodical report printing. Radiologist workbench in ProGraph is equipped with a medical printer SONY-UP-990AD (or similar), which prints on roll termopaper. Besides, it is possible to connect to the station any device of the medical institution, which has integrated possibilities of DICOM print.
ProGraph software meets the requirements of the DICOM 3.0 international protocol, which contains the latest changes of the standard of 2004 (with picture image compression JPEG2000) and possibilities of printing on DICOM-printers. That permits, when necessary, to integrate it into any modern medical informational system. The program is being developed in close cooperation with radiologists, so it contains not only generally accepted formalized protocols, but also the necessary forms of periodical reports. The program possesses wide opportunities of processing the received images through special filters.
