Modular open-source imaging phantom

Motivation: Overcome the high cost, lack of customisation and low global uptake of standard MRI imaging phantoms. Goal(s): Design an affordable open-source MRI imaging phantom, imaging protocols and analysis tools demonstrated, showcasing their efficacy through the evaluation of slice profile and spatial resolution assessment. Approach: A complex, multilayered phantom is designed with careful material selection aimed at low cost (US$500 worth of materials) and accessible construction principles. Slice profile and resolution measurements were performed using a double-wedge and a coarse resolution grid, respectively. Results: This study has successfully produced an affordable open-source imaging phantom with detailed MRI assessment protocols. Impact: This project's affordable, open-source MRI phantom and specialised assessment protocol benefit researchers by reducing costs and encouraging collaboration. The findings on slice profiles and resolution parameters enhance MRI research, improving imaging outcomes and accessibility.
