✦ Synopsis

Unsharp masking-in many forms-is a frequent technique in image enhancement. Various versions of unsharp masking are described together with the related dynamic exposure control techniques. Detailed analyses of these techniques are appended. fV(x) dx= I fie(x) dxl.

Clearly, the first member can not exceed the last member. Hence the initial condition implies that P(x) is not real and positive everywhere.

The chemical-shift effect often degrades slice selectivity thereby degrading the contrast and spatial resolutions in a high-field NMR imaging. We propose a new pulse sequence which can compensate for this chemical-shift effect during slice selection. This technique provides correct slice definition
