METHOD FOR PRODUCING X-RAY IMAGE Russian patent published in 2005 - IPC

FIELD: medical engineering.

SUBSTANCE: method involves forming X-ray radiation flow, letting pass it through filter transparent mainly for high power radiation spectrum portion of X-ray tube. The filter is mounted in front of volume under study. The X-ray radiation flow is directed to transducers for recording X-ray radiation quanta. Data are read from the transducers and image is built by applying computer software. An additional X-ray radiation flow is let pass through the filter transparent mainly for low power radiation spectrum portion of X-ray tube and mounted in front of volume under study. Another embodiment of the invention is characterized with scanning X-ray radiation flow being produced. High power radiation spectrum portion is directed to a transducers row for recording X-ray radiation quanta. X-ray radiation flow is additionally let pass through the filter transparent mainly for low power radiation spectrum portion of X-ray tube and mounted in front of volume under study. The X-ray radiation flow is directed to an additional transducers row for recording X-ray radiation quanta set in parallel to the available row.

EFFECT: high quality of diagnosis.
