The present invention provides method of generating a 3-D image of at least one cement bolus in relation to a bone comprising acquiring a plurality of fluoroscopic images of the bolus during or after a bone cement injection procedure. The method further comprises registering each fluoroscopic image with a CT scan image of the bone. Additionally, the method comprises outlining the bolus in each fluoroscopic image to generate a plurality of silhouettes of the bolus. The method also comprises projecting the silhouettes on to the CT scan image to generate a plurality of back-projections. Moreover, the method comprises identifying a plurality of bolus voxels to generate the 3-D image of the bolus, wherein each bolus voxel comprises an intersection of at least two back-projections. Furthermore, a method for intra-operative imaging of at least one bolus of bone cement during a bone cement injection procedure is disclosed.
