XXI. századi csúcstechnológia a PTE Térségi Szűrő- és Diagnosztikai Központjában (TSZDK) II. rész

Absztrakt:

Az IME előző számában a Pécsi Térségi Szűrő és Diagnosztikai Központban telepített képalkotó műszerek közül a computer tomográfiás és angiográfiás berendezést mutattuk be. A cikk második részében a mammográfiás berendezést, a flat detektoros felvételi berendezéseket és az EOS berendezést ismertetjük.

Abstract:

As digital technique improves, the importance of direct radiography methods applying flat detectors are increasing. The authors are describe the newest installed digital radiography units in the Screening and Diagnostic Center of Pécs University. Mammomat Novation DR (with spatial resolution level reaching 70 μm), Axiom Luminos TF, Aristos FX by Siemens and EOS by Biospace are discussed. EOS is an ultra low dose full body X-ray scanner producing simultaneous frontal and lateral images of the whole body in upright position. Due to the well-collimated thin beams of X-ray, vertical distorsion is excluded and the image quality is not destroyed by scattered rays. EOS is based upon a patented particle detector technology for which Georges Charpak received the Nobel Prize in Physics, which enables acquisition of radiographic images with 8-10 times lower dose of irradiation than conventional X- ray machines. The digital images are sent and stored in the AccessNet PACS system through the high speed LAN connection. The authors try to show how the x-ray units developed in the last some years.
