Abstract
The invention relates to an MR device with means for localizing and/or visualizing a medical instrument (2) inserted into an object (1) to be examined. In order to construct such a device in a more economical and more reliable manner, according to the invention the medical instrument (2) is provided with a magnet device (3) which is controllable by means of a control unit (4, 5) in such a manner that information concerning the position of the magnet device (3) in MR data sets can be specifically changed. The invention also relates to a corresponding MR method.
Claims9
An MR device with means for localizing and/or visualizing a medical instrument (2) inserted into an object (1) to be examined, characterized in that the medical instrument (2) is provided with a magnet device (3) and that the magnet device (3) can be controlled by means of a control unit (4, 5) in such a manner that information concerning the position of the magnet device (3) in MR data sets can be changed in a specific manner.
An MR method for localizing and/or visualizing a medical instrument (2) inserted into an object (1) to be examined, characterized in that the medical instrument (2) is provided with a magnet device (3) whereby information concerning the position of the magnet device (3) in MR data sets to be acquired can be changed in a specific manner and that the magnet device (3) is controlled by means of a control unit (4, 5) in such a manner that for the localization and/or visualization of the medical instrument (2) there is acquired an MR data set which contains information concerning the position of the magnet device (3), and otherwise MR data sets without information, or with changed information, concerning the position of the magnet device (3) are acquired.
