A process for the representation of the position of a medical instrument in an x-ray image and to a medical instrument and a medical system for carrying out the method

摘要

A process for the representation of the position of a with an x-ray marker (10) and a movement sensor (12) provided with a medical instrument (6) in an x-ray image (16) comprising the steps of:a) a the image (a_Rm) of the x-ray marker (10) of the result in a first position (l₁) medical instrument (6) located containing x-ray image (16) is generated,b) on the basis of the image (a_Rm) of the x-ray marker (10) in the x-ray image (16) are coordinates of the first layer (l₁) of the medical instrument (6) in the coordinate system (kos_Rb) of the x-ray image (16) and thus in the coordinate system (kos_Rg) the x-ray device (4) is determined,c) of the movement sensor (12), in the case of is in the first position (l₁) when the medical instrument (6), after receiving the x-ray image (16) initialized automatically,d) according to a movement of the medical instrument (6) of the first layer (l₁) in a second position (l₂) by means of the movement sensor (12) relative positional co-ordinates (δ_{L1, l2}) with respect to the first layer (l₁) in the coordinate system (kos_Rg) of the x-ray apparatus (4) is determined,e) on the basis of the coordinates of the first layer (l₁) of the medical instrument (6) in the coordinate system (kos_Rg) the x-ray device (4) and on the basis of the relative position coordinates (δ_{L1, l2}) , coordinates of the second layer (l₂) of the medical instrument (6) in the coordinate system (kos_Rg) the x-ray device (4) and thus in the coordinate system (kos_Rb) the x-ray image (16) is determined,f) the second layer (l₂) of the medical instrument (6), in the x-ray image (16) shown.
