摘要： A method for obtaining nuclear medical images of a patient in which one or more first images are obtained. The one or more first images can be used to identify one or more regions of interest for subsequent images that focus on the regions of interest. The process can occur iteratively until it is determined, either by a physician or a computer program that sufficient images have been obtained to identify lesions or other pathology within a reasonable level of confidence.
