A New Correction Algorithm of the Eccentric Ultrasonovision Time Image in the Casing Hole
《Applied Mathematics》2014年第10期1427-1431,共5页Jihui Tu Bin Yang 
The ultrasonovision image caused by the tool eccentricity can often present two pieces of vertical black strips in the Casing Well. To solve this problem, this paper proposes a correction algorithm of time eccentricit...
