摘要： Embodiments of systems and methods are disclosed for evaluating a superabrasive material by a three-dimensional model generated using a computed tomography scanner. The model is analyzed to identify a superabrasive matrix within the model and at least one performance characteristic of the superabrasive material is determined according to at least one property of the superabrasive matrix. Methods are also disclosed for characterizing crystal-to-crystal bonding regions and non-superabrasive material within an interstitial matrix of the superabrasive matrix.
