Up to 80% time savings for simulation engineers Accurate modeling of biomechanical behavior in one day In the biomedical field, simulating accurate models of complex biological structures has long posed a formidable challenge. Traditional mesh-based methods fall short when dealing with flawed or unconventional geometries such as CT scans, often requiring tedious surface reconstruction. This hinders the development of personalized medical treatments, leaving a gap in effective healthcare solutions.
To tackle this challenge, we leveraged the quasi-meshless finite cell method (FCM) for the simulation of a femoral bone CT scan, eliminating the time-consuming meshing process while still achieving precise simulations. Furthermore, the Keyak & Falkinstein approach was used to directly map CT scan data (Hounsfield Units) to material properties (Young’s Modulus). By being able to read the material properties of the bone encoded in the data from the scan, skip over the meshing stage, and directly simulate those data points, we make advanced medical simulations more accessible without the manual input of mesh experts or simulation engineers.
The final result was a groundbreaking method that enabled direct simulation of CT data, accurately representing material variations without the need for file conversion or approximation and significantly streamlining the process of developing personalized medical solutions. Notably, we achieved precise modeling of real-life biomechanical behaviors - such as those exerted during walking - on the modeled bone structure.
