Comparison of 3D-printed phantoms for testing cerebral oximeter performance (Conference Presentation)

Paper Abstract

We have optimized our prior phantom-based test method for cerebral oximetry performance using a new 3D-printed cerebrovascular module (CVM). In addition, we have and added a surrogate for a thin perfused scalp layer to evaluate perfusion- related confounding factors. The new CVM’s optical properties better represented biological tissue and also incorporated a water-mimicking dye. The modular phantom also included biologically relevant scalp/skull and cerebrospinal fluid (CSF) layers. Performance testing of two commercially available clinical oximeters with the modified CVM over a range of oxygen saturation levels illustrates the utility of our solid phantom-based approach for standardized cerebral oximeter performance assessment.
