Title: Image intensity correction method in MRI system
Inventor: GOERTLER GEORG DIPL PHYS
IPC: G01R33/565
Filed: 1996-12-20
Abstract: The method involves correcting a source image which comprises an uneven but only slightly changing sensitivity characteristic over its image area. Intensity changes between adjacent pixels are searched for in at least one direction. The intensity value of a pixel is changed to a value representing a maximum intensity change, when the intensity value changes more than a predetermined value. An auxiliary image is produced by this substitution, which subsequently undergoes a low-pass filtering. Sensitivity values corresponding to the pixels are produced from the intensity distribution of the filtered, auxiliary image. The intensity values of the source image are weighted with a reciprocal value corresponding to the sensitivity values.

Title: Nondestructive determination of metal hardness
IPC: G01N3/06
Filed: 1997-05-21
