An apparatus for displaying a moving region of interest located within a body, comprising: means configured to generate a motion compensation function based on the motion of the ROI; a positioning system comprising a first invasive location sensor (24 1) configured to be associated with the moving region of interest and being configured to determine a series of ROI position and orientation readings from the first invasive localization sensor (24 1), said means configured to generate said motion compensation function being responsive to said series of ROI position and orientation readings from the first invasive location sensor (24 1), said positioning system further comprises a second location sensor associated with an invasive medical device and being further configured to determine a device position and orientation (P&O) reading from the second localization sensor (24 2); means configured to correct the determined device position and orientation (P&O) reading of the medical device using the motion compensation function to thereby compensate for the motion of the ROI between a first time at which an image of the ROI was acquired and a second time, different from the first time, at which the device P&O was determined; and means configured to superimpose a representation of the medical device on the image acquired at the first time in accordance with the corrected device position and orientation. means configured to generate a motion compensation function based on the motion of the ROI; a positioning system comprising a first invasive location sensor (24 1) configured to be associated with the moving region of interest and being configured to determine a series of ROI position and orientation readings from the first invasive localization sensor (24 1), said means configured to generate said motion compensation function being responsive to said series of ROI position and orientation readings from the first invasive location sensor (24 1), said positioning system further comprises a second location sensor associated with an invasive medical device and being further configured to determine a device position and orientation (P&O) reading from the second localization sensor (24 2); means configured to correct the determined device position and orientation (P&O) reading of the medical device using the motion compensation function to thereby compensate for the motion of the ROI between a first time at which an image of the ROI was acquired and a second time, different from the first time, at which the device P&O was determined; and means configured to superimpose a representation of the medical device on the image acquired at the first time in accordance with the corrected device position and orientation. means configured to correct the determined device position and orientation (P&O) reading of the medical device using the motion compensation function to thereby compensate for the motion of the ROI between a first time at which an image of the ROI was acquired and a second time, different from the first time, at which the device P&O was determined; and means configured to superimpose a representation of the medical device on the image acquired at the first time in accordance with the corrected device position and orientation.
