Prior to performing a medical procedure, physicians are increasingly relying on access to 3-D printed models created using patient-specific medical data. Unfortunately, current 3-D data processing workflows can be extremely time consuming, and frequently, the resulting 3-D-printed models fail to accurately depict the anatomical details of interest. Motivated by these inherent limitations, an international team of researchers describes a rapid method for creating extremely detailed physical models directly from volumetric data stacks in an article published in 3-D Printing and Additive Manufacturing.
