[P047] Ultrasound Imaging: Towards Smaller Portable Systems Using Signal and Image Processing Tools

Based on the above values, TR and TE parameters were modified resulting in an optimized T1wSE sequence TR/TE = 1200 ms/10 ms and an optimized T2wTSE sequence TR/TE = 9500 ms/280 ms as estimated on a clinical MAGNETOM Sonata 1.5T system.Clinical MRI inter-equipment variability for T1 and T2 measurements remained <5% during a total sampling period of 2 months.TR and TE parameter variation in optimized T1w and T2w sequences remained less than 7% amongst the selected MRI systems included in this study.Conclusions.CNR optimization of T1w and T2w sequences for neonatal brain imaging at multiple 1.5T clinical MRI systems was accomplished with the aid of an in house developed tissuemimicking phantom.
