MR imaging of short relaxation times spin systems has been a widely discussed topic with serious clinical applications and led to the emergence of fast imaging ultra-short echo-time sequences such as UTE and ZTE. Nevertheless, these sequences suffer from image blurring due to the related point-spread function and are highly prone to imaging artefacts arising from e.g. chemical shifts or magnetic susceptibilities. In this work, we present a fully functional concept of spherical quasi-random single-point imaging that is highly acceleratable due to intrinsic undersampling properties and capable of strong metal artefact suppression with high tissue contrast.
