Dynamic CT imaging of bone cement injection through aluminium foam

The process of vertebroplasty is experimentally simulated by injecting a commercially available bone cement (rheology previously characterised) into a piece of aluminium foam (diameter 40 mm) with pore structure similar to that of cancellous bone inside a vertebra. The cement infiltration pattern is captured using a dynamic CT imaging setup. The bone cement is injected with a flow rate of 0.4 mL/s. The dynamic CT imaging setup captures CT images at a frequency of 2.5 Hz and resolution of 0.2 x 0.2 x 0.625 mm. The results are given in two forms: 1. The .am files are CT images with numbers in chronological order starting at time t=0, then 0.4 s, 0.8 s, and so on. The files are in .am format that can be opened using the software Amira. 2. The injection force required to maintain the flow rate is given in the form of .csv file named 'Injection_Force'.
