ABSTRACT
<p><b>OBJECTIVE</b>To develop a new method of PET and CT cross-modality medical image fusion based on out-location frame.</p><p><b>METHODS</b>PET/CT cross-modality medical images were obtained based on the out-location frame and the external fiducial marker on the frame was used for rigid medical image registration. A variation model based on the wavelet transform was used for image fusion.</p><p><b>RESULTS</b>The CT images were displayed by grey scale and overlaid with the PET images displayed by chromatic scale to obtain the image after registration and fusion.</p><p><b>CONCLUSION</b>The method of external markers registration can be effective and accurate in achieving PET and CT image fusion.</p>
