Liver Tumors 104We propose a new method for detecting tumors in CT images.Our method is based on adaptive contrast enhancement and the expectation maximization / maximization of the posterior marginal (EM/MPM) algorithm.User interaction is not required and both large and small tumors can be accurately found.Compared with our previously reported method [6], the newly proposed method is also suitable for images with poor contrasts.We describe the method in Sections 2-6 and present the experimental results in Section 7, followed by our conclusions.www.intechopen.
