| Research Abstract |
We created a novel device consisted of micro-flow sensor element and transmitting/receiving circuit to detect spinal cord ischemia. The sensor unit could detect Doppler shift generated by artificial blood flow within a vascular phantom mimicking Adamkiewicz artery. Further modifications are warranted to improve S/N ratio before we introduce the catheter into the clinical arena.
