  • Methods and systems for attentuation correction in medical imaging
    Patent number: 7729467
    Abstract: 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 a value for each pixel that represents the maximum density measurement for the pixel throughout the cine acquisition. In one embodiment, an attenuation correction image of a volume of interest is constructed by weighting a combination of the maximum pixel intensity value and an average pixel intensity value. Undesirable motion artifacts can be removed from positron emission tomography (PET) images by utilizing the CT attenuation correction image.
