Nonlinear amplitude compression in magnetic resonance imaging: quantization noise reduction and data memory saving
1990
IEEE Aerospace and Electronic Systems Magazine
Preserved Fulltext
Dynamic range improvement in magnetic resonance imaging by nonlinear amplitude compression is proposed and the quantization noise reduction by a factor of 10 to 20 is confirmed by a numerical simulation. The implementation of the amplitude compression requires no additional hardware in a usual MRI system if the low spatial frequency lines of the MR signal are selectively prescanned through an attenuator. This method will be particularly effective in 3D imaging of large objects, MR angiography and imaging of solids.
