ABSTRACT:
Prior to an intervention, a 3D rotational scan is acquired (at block10) in respect of a body volume and reconstructed. In addition, three-dimensional image data in respect of the body volume is acquired (at block12) using another modality, such as computerised tomography (CT) or magnetic resonance (MR), reconstructed, and prepared for visualisation. During the actual intervention, live two-dimensional fluoroscopic images are acquired (at block14), using the imaging system employed to acquire the 3D rotational scan, and processed for visualisation. The 2D image data is registered (at block16) to the 3D rotational image data acquired and reconstructed in respect of the body volume of interest, and then a 3D-3D registration process is employed (at block18) to register the 3D image data acquired in respect of the same body volume using, for example, CT or MR imaging systems to the 3D rotational image data, and a display module (20) is used to align the 2D fluoroscopic image and the 3D MR/CT image as a fused or composite image and display the image.
