Motivation: Optimum antenna allocation within the MRI bore is essential for reliable wireless link establishment. Goal(s): Our goal was to identify a sweet spot for in-bore antenna integration. Approach: We utilized time domain pulse distortion metric to evaluate various link fidelities. Results: Study results suggest that the antenna allocation at the middle of the birdcage circumference may produce the minimum pulse distortion and interference. Impact: A time domain pulse distortion metric may provide useful design information to system engineers for reliable in-bore wireless link establishment over a desired bandwidth.
