Bone imaging. (A) Picture of the imaged segment of a bovine tibia. (B) Comparison of PETRA and HYFI, with amplitude coefficient A, total scan time T_scan (min:s), relative total scan time for the same SNR, τ_scan (including both inner and outer k‐space), and the images acquired with Δt = 40 μs. They show virtually identical quality but the HYFI scan is considerably faster. (C) Maximum intensity projection of the HYFI image demonstrating high image quality over the whole field of view. The glue fixing the copper coil to the glass support and the tape holding the sample to the bed are also depicted. This figure illustrates that HYFI allows substantial increase in scan efficiency compared with PETRA for high‐resolution imaging of tissues with T ₂s of hundreds of microseconds, such as in bone in case large gaps are involved.
