COORDINATE FRAME FOR CARRYING OUT X-RAY TOPOMETRIC EXAMINATION Russian patent published in 2002 - IPC

FIELD: medical engineering. SUBSTANCE: device has body manufactured from rigid radiopaque material having central square window and four triangular coordinate marks arranged on the window borders so that straight lines drawn through their apices build rectangular cross-hair, through raster is available in each of four sides of the device body. Raster members are arranged in perpendicular to the frame body base and in parallel to the corresponding coordinate axes. The raster is adjacent to scintillator unit optically conjugated with semiconductor detector connected to computer through analog-to-digital converter. Raster grooves walls are inclined on the window side towards X-ray radiation source. EFFECT: enhanced accuracy and reliability of visceral organ topometry. 5 dwg
