Study on 2 Channel Application of Microscopy Coil Using Self-made Phantom

Motivation: Microscopy coil has high spatial resolution and SNR, but it has a limited effective Signal Intensity(SI) range. Goal(s): This study suggests a method to improve SI & effective SI range by various combinations of Microscopy Coil. Approach: We made a MRI Marker Phantom and analyzed SI using Microscopy Coil with 1channel (23mm, 47mm), 2channel (23+47mm, 23+23mm, 47+47mm). We measured effective SI range and SI. Results: In the results, SI of 2channel was higher than that of 1channel in all 12 ROI. Furthermore, change of changing of sense factor showed no significant change. Effective SI range was 47+47mm, 23+47mm, 47mm, 23+23mm, 23mm coil respectively. Impact: Various combinations of Microscopy 2channel Coil had advantage of increasing Signal Intensity(SI) and effective SI range compared to 1channel. Also use of sense factor in 2channel can reduce scan duration without SI change for patients who have difficulty in cooperating.
