    摘要: Methods and systems for imaging a patient are provided. The method includes scanning a patient and acquiring a plurality of frames of cine computed tomography (CT) images during one complete respiratory cycle. In one embodiment, a method is provided that includes selecting an organ of interest in the cine CT data and selecting a value for each pixel in the organ of interest that represents the maximum density measurement. An attenuation corrected positron emission tomography (PET) image is constructed based on the maximization of the pixel intensity of the organ of interest in the CT attenuation correction map. Incorrect attenuation correction values for PET images can be avoided by utilizing the CT attenuation correction map.

    摘要: A kit and teaching method for creating an artwork includes instructing the user to mark a surface with a line to divide the surface into sections, and to draw a pattern or patterns from provided samples within one of the sections. The user is then instructed to repeat this pattern in one or more other sections.
