Towards Autonomous MR imaging: World models

MR imaging is a powerful and diverse imaging technique employed to investigate and diagnose a range of diseases. MRI scans are acquired by employing specific parameters in a “sequence” to encode in data in arbitrary space known as “k-space”. Image is reconstructed by applying mathematical transforms (mainly Fourier) to the k-space data. To obtain images of particular contrast (T1w, T2w, T2* etc) optimal sequence settings must be employed. Briefly, image contrast arises from the magnetic property of hydrogen atoms, and image contrast can be varied using setting such as echo time…
