Figure 3From: MRI active guidewire with an embedded temperature probe and providing a distinct tip signal to enhance clinical safetySNR maps of guidewire (distal tip solder) for 0.61 cm, 0.71 cm, 0.81 cm coil diameter and 1 cm, 2.5 cm, 5 cm coil length configurations. Increasing coil diameter results in brighter tip signal. Increasing coil length changes the shaft signal profile and tip signal intensity.Back to article page
