ABSTRACT:
An image fusion method for medical applications, comprising:a. acquiring a first image with a planned radiation region;b. acquiring a second image with actual radiation region;c. determining if user defined landmarks have been placed on the first and second images, if user defined landmarks are present go to step (d), if not go to step (e);d. pre-transforming the first image or second image or both images;e. performing a first delineation step on the actual radiation region;f. determining if the delineation is correct, if yes go to step (g), if not go to step (h);g. fusing the first and second image and exit process; andh. selecting multiple contour points around the actual radiation region in the second image;i. performing a second delineation step on the actual radiation region and go to step (f).
