Open-Source Image-Based Tool to Experimentally Evaluate Blood Residence Time in Clinical Devices

This article introduces an open-source tool to experimentally compare blood residence time in biomedical devices using an image-based method. The experimental setup and the postprocessing workflow are comprehensively elucidated in a detailed report that conducts a thorough comparison of the residence times of a blood analog within three distinct blood oxygenator prototypes. To enable widespread accessibility and ease of use, the user-friendly MATLAB App developed for the analysis is available on the Mathworks repository: https://www.mathworks.com/matlabcentral/fileexchange/135156 .
