  • 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.
    Type: Grant

  • Device-less gating of physiological movement for improved image detection
    Patent number: 7574249
    Abstract: A method of imaging an object using a medical imaging system is provided. The imaging method acquires a stream of sinogram data. Changes in the stream of sinogram data corresponding to movement of the object are detected. The method selects portions of the stream of sinogram data. An image of the object based on the selected portions of the sinogram data is generated.

  • Methods and apparatus for 4DCT imaging systems
    Patent number: 7443946
    Abstract: A method includes receiving cine scan data, receiving a plurality of target phases of a periodic waveform, and generating a plurality of images, each image centered at one of the received target phases. A phase shall represent a percentage of a period of a repeating cycle.
