We investigated accelerating two paradigms of in vivo diaphragm imaging using a 0.5T upright scanner. These two paradigms, high resolution and low resolution, were optimised to deliver minimal artefacts and maximal information about the diaphragm surface. These scans delivered sufficient image quality for the tissue boundary of the diaphragm to be located. This will allow for future work to study the diaphragm in the upright position of participants with COPD who are only able to hold their breath for ~5 sec.
