Abstract
With the accelerated development of medical imaging equipment and techniques, image fusion technology has been effectively applied for diagnosis, biopsy and radiofrequency ablation, especially for liver tumor. Tumor treatment relying on a single medical imaging modality might face challenges, due to the deep positioning of the lesions, operation history and the specific background conditions of the liver disease. Image fusion technology has been employed to address these challenges. Using the image fusion technology, one could obtain real-time anatomical imaging superimposed by functional images showing the same plane to facilitate the diagnosis and treatments of liver tumors. This paper presents a review of the key principles of image fusion technology, its application in tumor treatments, particularly in liver tumors, and concludes with a discussion of the limitations and prospects of the image fusion technology.

In the modern clinical practices, physicians have a higher demand on the accuracy and efficiency of a visually-aided medical diagnostic system
Summary
Medical imaging equipment has developed rapidly in the last decade, with widespread usage in clinical diagnosis and treatment. The functional imaging mode mainly provides functional metabolic information One such method is single photon emission computed tomography (SPECT). SPECT imaging instruments provide three-dimensional (tomographic) images of the distribution of radioactive tracer molecules introduced into the body which is generated from multiple 2D images of the body at different angles [3] Another widely used method in this mode is positron emission tomography (PET). An optimal combination of these methods can allow a simultaneous expression of information from various aspects of the human body within a single image Such an image can accurately reflect internal structure and function, in turn providing physiological and pathological information.
