Reverse Engineering of Some Cardiovascular Devices

An X-Ray microtompgraphic and a laser based method have been used for getting surface scan of some cardiovascular devices. Several stent and mechanical heart valve types have been scanned, highlighting the advantages and disadvantages of each method. The major advantage of X-Ray microtomography is the possibility of evaluating the mass distribution inside the sample, whilst the laser scanning is independent of the density of the sample.
