Ultrashort Echo-Time (UTE) imaging techniques can visualize short T₂* components (i.e., bone). Dual-echo UTE imaging was performed with hyperbolic tangent based R₂* model to separate the bone and soft tissue. This work demonstrated that cortical bone and bone marrow of skull are well separated with soft tissue using dual-echo UTE images. The proposed method can potentially be used for MR-only transcranial HIFU planning and PET attenuation correction.
