Study on Ultra-wideband Multiple Differential Recursive Imaging of stroke: A recursive brain imaging solution for stroke detection.

In stroke detection using ultra-wideband tomography, the structure of the skull and its reflection have always been a major factor affecting brain imaging accuracy. In this paper, we propose the Multiple Differential Recursive Imaging solution to eliminate the reflection by performing several forward problem analyses. The system is designed for operation at a single frequency of 1 GHz, and a 2-dimensional head model is developed for experimental analyzes. By experimental verification, the MDRI has a stable imaging capability on different bleeding sizes and numbers, and the images are properly reconstructed.
