The Algorithm of Rapid Medical Image Registration by Using Mutual Information
This paper presents a rapid algorithm for medicalimage registration, the purpose is to solve problems, which arethe inferiority of low speed and huge calculation in medicalimages registration based on normal mutual information. Wepresent a two-step search strategy to speed-up registrationprocess according to the different regions between the targetimage and the source image. In a first step the coarse granularitysearch determines the limits of target range; between-classdistance is used in the initial step for discriminating similarity. Ina second step the fine-grained search computes similaritymeasure by using normalized mutual information to achieve finalimage registration. Experimental results show that the method,which keeps precision of registration, can solve the problem oflow speed, and achieve good effects.
