摘要:
A system for bone imaging is disclosed. A processing unit is provided for processing an echo MRI dataset. The processing unit is configured to apply a phase ramp to the radial sampling lines of the complex data according to the radial sampling scheme to obtain a bone-enhanced image dataset, wherein a single phase ramp is applied to a radial sampling line of the sampling scheme, which radial sampling line extends on both sides of an origin defined by the echo time, and wherein the phase ramp is based on an equation. A combining unit is provided for combining the MRI dataset with the bone-enhanced image dataset to obtain a background suppressed image dataset.
