Abstract : We present a method to merge two distinct CT scans acquired from dif- ferent patients such that the second scan can supplement the first when it is missing necessary supporting anatomy. The aim is to provide vascular intervention simula- tions with full body anatomy. Often, patient CT scans are confined to a localised region so that the patient is not exposed to more radiation than necessary and to increase scanner throughput. Unfortunately, this localised scanning region may be limiting for some applications where surrounding anatomy may be required and where approximate supporting anatomy is acceptable. The resulting merged scan can enhance body navigation simulations with X-ray rendering by providing a com- plete anatomical reference which may be useful in training and rehearsal. An ex- ample of the use of our CT scan merging technique in the field of interventional radiology is described.
